Enable tooltips by default, and don't enable them when setting the
tooltip value, since that will negate any changes a program might
make when displaying the file chooser dialog, etc.

<H3>Description</H3>
<P>This is the FLTK text input widget. It displays a single line of text
and lets the user edit it. Normally it is drawn with an inset box and
a white background. The text may contain any characters (even 0), and
will correctly display anything, using ^X notation for unprintable
control characters and \nnn notation for unprintable characters with
the high bit set. It assumes the font can draw any characters in the
ISO-8859-1 character set.
<CENTER><TABLE border=1 WIDTH=90% summary="Fl_Input keyboard and mouse bindings.">
<P>This is the FLTK text display widget. It allows the user to
view multiple lines of text and supports highlighting and

sequence. The next one or two keys typed define the character to
insert (see table that follows.)
<p>For instance, to type "á" type [compose][a]['] or [compose]['][a].
<P>The character "nbsp" (non-breaking space) is typed by using
[compose][space].
<P>The single-character sequences may be followed by a space if
necessary to remove ambiguity. For instance, if you really want to
type "ª~" rather than "ã" you must type [compose][a][space][~].
<p>The same key may be used to "quote" control characters into the
text. If you need a <tt>^Q</tt> character you can get one by typing
[compose][Control+Q].
<p>X may have a key on the keyboard
defined as <tt>XK_Multi_key</tt>. If so this key may be used as well
as the right-hand control key. You can set this up with the program
<tt>xmodmap</tt>.
<p>If your keyboard is set to support a foreign language you should
also be able to type "dead key" prefix characters. On X you will
actually be able to see what dead key you typed, and if you then move
the cursor without completing the sequence the accent will remain
inserted.

<H4><A name=Fl_Input.Fl_Input>Fl_Input::Fl_Input(int x, int y, int w,
int h, const char *label = 0)</A></H4>
Creates a new <TT>Fl_Input</TT> widget using the given position, size,
and label string. The default boxtype is <TT>FL_DOWN_BOX</TT>.
<H4><A name=Fl_Input.~Fl_Input>virtual Fl_Input::~Fl_Input()</A></H4>
Destroys the widget and any value associated with it.
<H4><A name=Fl_Input.value>const char *Fl_Input::value() const
<BR> int Fl_Input::value(const char*)
<BR> int Fl_Input::value(const char*, int)</A></H4>
The first form returns the current value, which is a pointer to the
internal buffer and is valid only until the next event is handled.
<P>The second two forms change the text and set the mark and the point
to the end of it. The string is copied to the internal buffer. Passing <TT>
NULL</TT> is the same as &quot;&quot;. This returns non-zero if the new value is
different than the current one. You can use the second version to
directly set the length if you know it already or want to put nul's in
the text. </P>
<H4><A name=Fl_Input.static_value>int Fl_Input::static_value(const
char*)
<BR> int Fl_Input::static_value(const char*, int)</A></H4>
Change the text and set the mark and the point to the end of it. The
string is <I>not</I> copied. If the user edits the string it is copied
to the internal buffer then. This can save a great deal of time and
memory if your program is rapidly changing the values of text fields,
but this will only work if the passed string remains unchanged until
either the <TT>Fl_Input</TT> is destroyed or <TT>value()</TT> is called
again.
<H4><A name=Fl_Input.size>int Fl_Input::size() const</A></H4>
Returns the number of characters in <TT>value()</TT>. This may be
greater than <TT>strlen(value())</TT> if there are nul characters in
it.
<H4><A name=Fl_Input.index>char Fl_Input::index(int) const</A></H4>
Same as <TT>value()[n]</TT>, but may be faster in plausible
implementations. No bounds checking is done.
<H4><A name=Fl_Input.when>Fl_When Fl_Widget::when() const
<BR> void Fl_Widget::when(Fl_When)</A></H4>
Controls when callbacks are done. The following values are useful,
the default value is <TT>FL_WHEN_RELEASE</TT>:
<UL>
<LI><TT>0</TT>: The callback is not done, but <TT>changed()</TT> is
turned on. </LI>
<LI><TT>FL_WHEN_CHANGED</TT>: The callback is done each time the text
is changed by the user. </LI>
<LI><TT>FL_WHEN_RELEASE</TT>: The callback will be done when this
widget loses the focus, including when the window is unmapped. This
is a useful value for text fields in a panel where doing the callback
on every change is wasteful. However the callback will also happen if
the mouse is moved out of the window, which means it should not do
anything visible (like pop up an error message). You might do better
setting this to zero, and scanning all the items for <TT>changed()</TT>
when the OK button on a panel is pressed. </LI>
<LI><TT>FL_WHEN_ENTER_KEY</TT>: If the user types the Enter key, the
entire text is selected, and the callback is done if the text has
changed. Normally the Enter key will navigate to the next field (or
insert a newline for a <TT>Fl_Mulitline_Input</TT>), this changes the
behavior. </LI>
<LI><TT>FL_WHEN_ENTER_KEY|FL_WHEN_NOT_CHANGED</TT>: The Enter key will
do the callback even if the text has not changed. Useful for command
fields. </LI>
</UL>
<H4><A name=Fl_Input.textcolor>Fl_Color Fl_Input::textcolor() const
<BR> void Fl_Input::textcolor(Fl_Color)</A></H4>
Gets or sets the color of the text in the input field.
<H4><A name=Fl_Input.textfont>Fl_Font Fl_Input::textfont() const

<H3>Description</H3>
<P>This is the FLTK text input widget. It displays a single line of text
and lets the user edit it. Normally it is drawn with an inset box and
a white background. The text may contain any characters (even 0), and
will correctly display anything, using ^X notation for unprintable
control characters and \nnn notation for unprintable characters with
the high bit set. It assumes the font can draw any characters in the
ISO-8859-1 character set.

sequence. The next one or two keys typed define the character to
insert (see table that follows.)
<p>For instance, to type "á" type [compose][a]['] or [compose]['][a].
<P>The character "nbsp" (non-breaking space) is typed by using
[compose][space].
<P>The single-character sequences may be followed by a space if
necessary to remove ambiguity. For instance, if you really want to
type "ª~" rather than "ã" you must type [compose][a][space][~].
<p>The same key may be used to "quote" control characters into the
text. If you need a <tt>^Q</tt> character you can get one by typing
[compose][Control+Q].
<p>X may have a key on the keyboard
defined as <tt>XK_Multi_key</tt>. If so this key may be used as well
as the right-hand control key. You can set this up with the program
<tt>xmodmap</tt>.
<p>If your keyboard is set to support a foreign language you should
also be able to type "dead key" prefix characters. On X you will
actually be able to see what dead key you typed, and if you then move
the cursor without completing the sequence the accent will remain
inserted.

<H4><A name=Fl_Input.Fl_Input>Fl_Input::Fl_Input(int x, int y, int w,
int h, const char *label = 0)</A></H4>
Creates a new <TT>Fl_Input</TT> widget using the given position, size,
and label string. The default boxtype is <TT>FL_DOWN_BOX</TT>.
<H4><A name=Fl_Input.~Fl_Input>virtual Fl_Input::~Fl_Input()</A></H4>
Destroys the widget and any value associated with it.
<H4><A name=Fl_Input.value>const char *Fl_Input::value() const
<BR> int Fl_Input::value(const char*)
<BR> int Fl_Input::value(const char*, int)</A></H4>
The first form returns the current value, which is a pointer to the
internal buffer and is valid only until the next event is handled.
<P>The second two forms change the text and set the mark and the point
to the end of it. The string is copied to the internal buffer. Passing <TT>
NULL</TT> is the same as &quot;&quot;. This returns non-zero if the new value is
different than the current one. You can use the second version to
directly set the length if you know it already or want to put nul's in
the text. </P>
<H4><A name=Fl_Input.static_value>int Fl_Input::static_value(const
char*)
<BR> int Fl_Input::static_value(const char*, int)</A></H4>
Change the text and set the mark and the point to the end of it. The
string is <I>not</I> copied. If the user edits the string it is copied
to the internal buffer then. This can save a great deal of time and
memory if your program is rapidly changing the values of text fields,
but this will only work if the passed string remains unchanged until
either the <TT>Fl_Input</TT> is destroyed or <TT>value()</TT> is called
again.
<H4><A name=Fl_Input.size>int Fl_Input::size() const</A></H4>
Returns the number of characters in <TT>value()</TT>. This may be
greater than <TT>strlen(value())</TT> if there are nul characters in
it.
<H4><A name=Fl_Input.index>char Fl_Input::index(int) const</A></H4>
Same as <TT>value()[n]</TT>, but may be faster in plausible
implementations. No bounds checking is done.
<H4><A name=Fl_Input.when>Fl_When Fl_Widget::when() const
<BR> void Fl_Widget::when(Fl_When)</A></H4>
Controls when callbacks are done. The following values are useful,
the default value is <TT>FL_WHEN_RELEASE</TT>:
<UL>
<LI><TT>0</TT>: The callback is not done, but <TT>changed()</TT> is
turned on. </LI>
<LI><TT>FL_WHEN_CHANGED</TT>: The callback is done each time the text
is changed by the user. </LI>
<LI><TT>FL_WHEN_RELEASE</TT>: The callback will be done when this
widget loses the focus, including when the window is unmapped. This
is a useful value for text fields in a panel where doing the callback
on every change is wasteful. However the callback will also happen if
the mouse is moved out of the window, which means it should not do
anything visible (like pop up an error message). You might do better
setting this to zero, and scanning all the items for <TT>changed()</TT>
when the OK button on a panel is pressed. </LI>
<LI><TT>FL_WHEN_ENTER_KEY</TT>: If the user types the Enter key, the
entire text is selected, and the callback is done if the text has
changed. Normally the Enter key will navigate to the next field (or
insert a newline for a <TT>Fl_Mulitline_Input</TT>), this changes the
behavior. </LI>
<LI><TT>FL_WHEN_ENTER_KEY|FL_WHEN_NOT_CHANGED</TT>: The Enter key will
do the callback even if the text has not changed. Useful for command
fields. </LI>
</UL>
<H4><A name=Fl_Input.textcolor>Fl_Color Fl_Input::textcolor() const
<BR> void Fl_Input::textcolor(Fl_Color)</A></H4>
Gets or sets the color of the text in the input field.
<H4><A name=Fl_Input.textfont>Fl_Font Fl_Input::textfont() const
<BR> void Fl_Input::textfont(Fl_Font)</A></H4>

Gets or sets the size of the text in the input field.

<h2>Functions</h2>
@ -235,858 +235,5 @@ subexpressions literally. </LI>
<LI><tt>x</tt> all other characters must be matched exactly. </LI>
</UL>
<h2>Fl:: Methods</h2>
<h3><A name=add_fd>static void Fl::add_fd(int fd, void (*cb)(int, void
*), void* = 0)
<br>static void Fl::add_fd(int fd, int when, void (*cb)(int, void*),
void* = 0)</A>
<br><A name=remove_fd>static void Fl::remove_fd(int)</A></h3>
Add file descriptor <tt>fd</tt> to listen to. When the <tt>fd</tt>
becomes ready for reading <tt>Fl::wait()</tt> will call the callback
and then return. The callback is
passed the <tt>fd</tt> and the arbitrary <tt>void*</tt> argument.
<P>The second version takes a <tt>when</tt> bitfield, with the bits
<tt>FL_READ</tt>, <tt>FL_WRITE</tt>, and <tt>FL_EXCEPT</tt> defined,
to indicate when the callback should be done.
<P>There can only be one callback of each type for a file descriptor. <tt>
Fl::remove_fd()</tt> gets rid of <I>all</I> the callbacks for a given
file descriptor.
<P>Under UNIX <I>any</I> file descriptor can be monitored (files,
devices, pipes, sockets, etc.) Due to limitations in Microsoft Windows,
WIN32 applications can only monitor sockets.
<h3><A name=add_handler>static void Fl::add_handler(int (*f)(int))</A></h3>
Install a function to parse unrecognized events. If FLTK cannot
figure out what to do with an event, it calls each of these functions
(most recent first) until one of them returns non-zero. If none of
them returns non zero then the event is ignored. Events that cause
this to be called are:
<UL>
<LI><tt>FL_SHORTCUT</tt> events that are not recognized by any widget.
This lets you provide global shortcut keys. </LI>
<LI>System events that FLTK does not recognize. See <A href=osissues.html#fl_xevent>
<tt>fl_xevent</tt></A>. </LI>
<LI><I>Some</I> other events when the widget FLTK selected returns
zero from its <tt>handle()</tt> method. Exactly which ones may change
in future versions, however. </LI>
</UL>
<h3><A name=add_idle>static Fl::add_idle(void (*cb)(void*), void*)</A></h3>
Adds a callback function that is called every time by
<tt>Fl::wait()</tt> and also makes it act as though the timeout is
zero (this makes <tt>Fl::wait()</tt> return immediately, so if it is
in a loop it is called repeatedly, and thus the idle fucntion is
called repeatedly). The idle function can be used to get background
processing done.
<P>You can have multiple idle callbacks. To remove an idle callback use <A
href=#remove_idle><tt>Fl::remove_idle()</tt></A>.
<P><tt>Fl::wait()</tt> and <tt>Fl::check()</tt> call idle callbacks,
but <tt>Fl::ready()</tt> does not.
<P>The idle callback can call any FLTK functions, including
<tt>Fl::wait()</tt>, <tt>Fl::check()</tt>, and <tt>Fl::ready()</tt>.
Fltk will not recursively call the idle callback.
<h3><A name=add_timeout>static void Fl::add_timeout(float t, void (*cb)(void*),void*v=0)</A></h3>
Add a one-shot timeout callback. The function will be called by
<tt>Fl::wait()</tt> at <i>t</i> seconds after this function is called.
The optional <tt>void*</tt> argument is passed to the callback.
<h3><A name=repeat_timeout>static void Fl::repeat_timeout(float t, void (*cb)(void*),void*v=0)</A></h3>
Inside a timeout callback you can call this to add another timeout.
Rather than the time being measured from "now", it is measured from
when the system call elapsed that caused this timeout to be called. This
will result in far more accurate spacing of the timeout callbacks, it
also has slightly less system call overhead. (It will also use all
your machine time if your timeout code and fltk's overhead take more
than <i>t</i> seconds, as the real timeout will be reduced to zero).
<p>It is undefined what this does if called from outside a timeout
callback.
<P>This code will print &quot;TICK&quot; each second on stdout, with a
fair degree of accuracy:
<UL><PRE>void callback(void*) {
printf(&quot;TICK\n&quot;);
Fl::repeat_timeout(1.0,callback);
}
main() {
Fl::add_timeout(1.0,callback);
return Fl::run();
}</PRE></UL>
<h3><A name=add_timeout>static void Fl::add_check(void (*cb)(void*),void*v=0)</A></h3>
Fltk will call this callback just before it flushes the display and
waits for events. This is different than an idle callback because it
is only called once, then fltk calls the system and tells it not to
return until an event happens.
<p>This can be used by code that wants to monitor the
application's state, such as to keep a display up to date. The
advantage of using a check callback is that it is called only when no
events are pending. If events are coming in quickly, whole blocks of
them will be processed before this is called once. This can save
significant time and avoid the application falling behind the events.
<p>Sample code:
<ul><pre>bool state_changed; // anything that changes the display turns this on
void callback(void*) {
if (!state_changed) return;
state_changed = false;
do_expensive_calculation();
widget->redraw();
}
main() {
Fl::add_check(1.0,callback);
return Fl::run();
}</pre></ul>
<h3><A name=arg>static int Fl::arg(int argc, char **argv, int &amp;i)</A></h3>
Consume a single switch from <tt>argv</tt>, starting at word i.
Returns the number of words eaten (1 or 2, or 0 if it is not
recognized) and adds the same value to <tt>i</tt>. You can use this
function if you prefer to control the incrementing through the
arguments yourself.
<h3><A name=args>static int Fl::args(int argc, char **argv, int &amp;i, int
(*callback)(int, char**,int &amp;)=0)
<BR>void Fl::args(int argc, char **argv)</A></h3>
FLTK provides an <I>entirely optional</I> command-line switch parser.
You don't have to call it if you don't like them! Everything it can do
can be done with other calls to FLTK.
<P>To use the switch parser, call <tt>Fl::args(...)</tt> near the start
of your program. This does <I>not</I> open the display, instead
switches that need the display open are stashed into static variables.
Then you <I>must</I> display your first window by calling <A href=Fl_Window.html#Fl_Window.show>
window-&gt;show(argc,argv)</A>, which will do anything stored in the
static variables.
<P><tt>callback</tt> lets you define your own switches. It is called
with the same <tt>argc</tt> and <tt>argv</tt>, and with <tt>i</tt> the
index of each word. The callback should return zero if the switch is
unrecognized, and not change <tt>i</tt>. It should return non-zero if
the switch is recognized, and add at least 1 to <tt>i</tt> (it can add
more to consume words after the switch). This function is called
<i>before</i> any other tests, so <i>you can override any FLTK
switch</i> (this is why fltk can use very short switches instead of
the long ones all other toolkits force you to use).
<P>On return <tt>i</tt> is set to the index of the first non-switch.
This is either:
<UL>
<LI>The first word that does not start with '-'. </LI>
<LI>The word '-' (used by many programs to name stdin as a file) </LI>
<LI>The first unrecognized switch (return value is 0). </LI>
<LI><tt>argc</tt></LI>
</UL>
The return value is <tt>i</tt> unless an unrecognized switch is found,
in which case it is zero. If your program takes no arguments other
than switches you should produce an error if the return value is less
than <tt>argc</tt>.
<P>All switches except -bg2 may be abbreviated one letter and case is ignored:
<UL>
<LI><tt>-display host:n.n</tt> The X display to use (ignored under
WIN32). </LI>
<LI><tt>-geometry WxH+X+Y</tt> The window position and size will be
modified according the the standard X geometry string. </LI>
<LI><tt>-name string</tt> Fl_Window::xclass(string) will be done to
the window, possibly changing its icon. </LI>
<LI><tt>-title string</tt> Fl_Window::label(string) will be done to
the window, changing both its title and the icontitle. </LI>
<LI><tt>-iconic</tt> Fl_Window::iconize() will be done to the window. </LI>
<LI><tt>-bg color</tt> XParseColor is used to lookup the passed color
and then Fl::background() is done. Under WIN32 only color names of
the form &quot;#xxxxxx&quot; are understood. </LI>
<LI><tt>-bg2 color</tt> XParseColor is used to lookup the passed color
and then Fl::background2() is done. </LI>
<LI><tt>-fg color</tt> XParseColor is used to lookup the passed color
and then Fl::foreground() is done. </LI>
</UL>
The second form of <tt>Fl::args()</tt> is useful if your program does
not have command line switches of its own. It parses all the switches,
and if any are not recognized it calls <tt>Fl::abort(Fl::help)</tt>.
<h3><A name=background>static void Fl::background(uchar, uchar, uchar)</A>
</h3>
Changes <tt>fl_color(FL_GRAY)</tt> to the given color, and changes the
gray ramp from 32 to 56 to black to white. These are the colors used
as backgrounds by almost all widgets and used to draw the edges of all
the boxtypes.
<h3><A name=background2>static void Fl::background2(uchar, uchar, uchar)</A>
</h3>
Changes <tt>fl_color(FL_WHITE)</tt> and the same colors as <tt>
Fl::foreground()</tt>. This color is used as a background by <tt>
Fl_Input</tt> and other text widgets.
<h3><A name=belowmouse>static Fl_Widget *Fl::belowmouse() const
<br>static void Fl::belowmouse(Fl_Widget *)</A></h3>
Get or set the widget that is below the mouse. This is for
highlighting buttons. It is not used to send <tt>FL_PUSH</tt> or <tt>
FL_MOVE</tt> directly, for several obscure reasons, but those events
typically go to this widget. This is also the first widget tried for <tt>
FL_SHORTCUT</tt> events.
<P>If you change the belowmouse widget, the previous one and all
parents (that don't contain the new widget) are sent <tt>FL_LEAVE</tt>
events. Changing this does <I>not</I> send <tt>FL_ENTER</tt> to this
or any widget, because sending <tt>FL_ENTER</tt> is supposed to <I>test</I>
if the widget wants the mouse (by it returning non-zero from <tt>
handle()</tt>).
<h3><A name=box_dh>static int Fl::box_dh(Fl_Boxtype)</A></h3>
Returns the height offset for the given boxtype.
<h3><A name=box_dw>static int Fl::box_dw(Fl_Boxtype)</A></h3>
Returns the width offset for the given boxtype.
<h3><A name=box_dx>static int Fl::box_dx(Fl_Boxtype)</A></h3>
Returns the X offset for the given boxtype.
<h3><A name=box_dy>static int Fl::box_dy(Fl_Boxtype)</A></h3>
Returns the Y offset for the given boxtype.
<h3><A name=check>static int Fl::check()</A></h3>
Same as <tt>Fl::wait(0)</tt>. Calling this during a big calculation
will keep the screen up to date and the interface responsive:
<ul><pre>while (!calculation_done()) {
calculate();
Fl::check();
if (user_hit_abort_button()) break;
}</pre></ul>
The returns non-zero if any windows are displayed, and 0 if no
windows are displayed (this is likely to change in future versions of
fltk).
<h3><A name=damage>static int Fl::damage()</A></h3>
If true then <A href=#flush><tt>flush()</tt></A> will do something.
<h3><A name=display>static void Fl::display(const char *)</A></h3>
Sets the X display to use for all windows. Actually this just sets
the environment variable $DISPLAY to the passed string, so this only
works before you show() the first window or otherwise open the display,
and does nothing useful under WIN32.
<h3><A name=enable_symbols>static void Fl::enable_symbols()</A></h3>
Enables the symbol drawing code.
<h3><A name=event_button>static int Fl::event_button()</A></h3>
Returns which mouse button was pressed. This returns garbage if the
most recent event was not a <tt>FL_PUSH</tt> or <tt>FL_RELEASE</tt>
event.
<h3><A name=event_clicks>int Fl::event_clicks()
<br>void Fl::event_clicks(int)</A></h3>
The first form returns non-zero if the most recent <tt>FL_PUSH</tt> or
<tt>FL_KEYBOARD</tt> was a &quot;double click&quot;. Returns N-1 for
N clicks. A double click is counted if the same button is pressed
again while <tt>event_is_click()</tt> is true.
<P>The second form directly sets the number returned by <tt>
Fl::event_clicks()</tt>. This can be used to set it to zero so that
later code does not think an item was double-clicked.
<h3><A name=event_inside>int Fl::event_inside(const Fl_Widget *) const
<br>int Fl::event_inside(int x, int y, int w, int h)</A></h3>
Returns non-zero if the current <tt>event_x</tt> and <tt>event_y</tt>
put it inside the widget or inside an arbitrary bounding box. You
should always call this rather than doing your own comparison so you
are consistent about edge effects.
<h3><A name=event_is_click>int Fl::event_is_click()
<br>void Fl::event_is_click(0)</A></h3>
The first form returns non-zero if the mouse has not moved far enough
and not enough time has passed since the last <tt>FL_PUSH</tt> or <tt>
FL_KEYBOARD</tt> event for it to be considered a &quot;drag&quot; rather than a
&quot;click&quot;. You can test this on <tt>FL_DRAG</tt>, <tt>FL_RELEASE</tt>,
and <tt>FL_MOVE</tt> events. The second form clears the value returned
by <tt>Fl::event_is_click()</tt>. Useful to prevent the <I>next</I>
click from being counted as a double-click or to make a popup menu
pick an item with a single click. Don't pass non-zero to this.
<h3><A name=event_key>int Fl::event_key()
<br>int Fl::event_key(int)</A>
<br><A name=get_key>int Fl::get_key(int)</A></h3>
<tt>Fl::event_key()</tt> returns which key on the keyboard was last
pushed. It returns zero if the last event was not a key press or release.
<P><tt>Fl::event_key(int)</tt> returns true if the given key was held
down (or pressed) <I>during</I> the last event. This is constant until
the next event is read from the server.
<P><tt>Fl::get_key(int)</tt> returns true if the given key is held down <I>
now</I>. Under X this requires a round-trip to the server and is <I>
much</I> slower than <tt>Fl::event_key(int)</tt>.
<P>Keys are identified by the <I>unshifted</I> values. FLTK defines a
set of symbols that should work on most modern machines for every key
on the keyboard:
<UL>
<LI>All keys on the main keyboard producing a printable ASCII
character use the value of that ASCII character (as though shift,
ctrl, and caps lock were not on). The space bar is 32. </LI>
<LI>All keys on the numeric keypad producing a printable ASCII
character use the value of that ASCII character plus <tt>FL_KP</tt>.
The highest possible value is <tt>FL_KP_Last</tt> so you can
range-check to see if something is on the keypad. </LI>
<LI>All numbered function keys use the number on the function key plus <tt>
FL_F</tt>. The highest possible number is <tt>FL_F_Last</tt>, so you
can range-check a value. </LI>
<LI>Buttons on the mouse are considered keys, and use the button
number (where the left button is 1) plus <tt>FL_Button</tt>. </LI>
<LI>All other keys on the keypad have a symbol: <tt>FL_Escape,
FL_BackSpace, FL_Tab, FL_Enter, FL_Print, FL_Scroll_Lock, FL_Pause,
FL_Insert, FL_Home, FL_Page_Up, FL_Delete, FL_End, FL_Page_Down,
FL_Left, FL_Up, FL_Right, FL_Down, FL_Shift_L, FL_Shift_R,
FL_Control_L, FL_Control_R, FL_Caps_Lock, FL_Alt_L, FL_Alt_R,
FL_Meta_L, FL_Meta_R, FL_Menu, FL_Num_Lock, FL_KP_Enter</tt>. Be
careful not to confuse these with the very similar, but all-caps,
symbols used by <A href="#event_state"><tt>Fl::event_state()</tt>
</A>. </LI>
</UL>
On X <tt>Fl::get_key(FL_Button+n)</tt> does not work.
<P>On WIN32 <tt>Fl::get_key(FL_KP_Enter)</tt> and <tt>
Fl::event_key(FL_KP_Enter)</tt> do not work.
<h3><A name=event_length>char *Fl::event_length()</A></h3>
Returns the length of the text in <tt>Fl::event_text()</tt>. There
will always be a nul at this position in the text. However there may
be a nul before that if the keystroke translates to a nul character or
you paste a nul character.
<h3><A name=event_state>ulong Fl::event_state()
<br>unsigned int Fl::event_state(ulong)</A></h3>
This is a bitfield of what shift states were on and what mouse buttons
were held down during the most recent event. The second version
returns non-zero if any of the passed bits are turned on. The legal
bits are:
<UL>
<LI><tt>FL_SHIFT</tt></LI>
<LI><tt>FL_CAPS_LOCK</tt></LI>
<LI><tt>FL_CTRL</tt></LI>
<LI><tt>FL_ALT</tt></LI>
<LI><tt>FL_NUM_LOCK</tt></LI>
<LI><tt>FL_META</tt></LI>
<LI><tt>FL_SCROLL_LOCK</tt></LI>
<LI><tt>FL_BUTTON1</tt></LI>
<LI><tt>FL_BUTTON2</tt></LI>
<LI><tt>FL_BUTTON3</tt></LI>
</UL>
X servers do not agree on shift states, and FL_NUM_LOCK, FL_META, and
FL_SCROLL_LOCK may not work. The values were selected to match the
XFree86 server on Linux. In addition there is a bug in the way X works
so that the shift state is not correctly reported until the first event <I>
after</I> the shift key is pressed or released.
<h3><A name=event_text>char *Fl::event_text()</A></h3>
Returns the ASCII text (in the future this may be UTF-8) produced by
the last <tt>FL_KEYBOARD</tt> or <tt>FL_PASTE</tt> or possibly other
event. A zero-length string is returned for any keyboard function keys
that do not produce text. This pointer points at a static buffer and is
only valid until the next event is processed.
<P>Under X this is the result of calling <tt>XLookupString()</tt>.
<h3><A name=event_x>static int Fl::event_x()
<br><A name=event_y>static int Fl::event_y()</A></A></h3>
Returns the mouse position of the event relative to the <tt>Fl_Window</tt>
it was passed to.
<h3><A name=event_x_root>static int Fl::event_x_root()
<br><A name=event_y_root>static int Fl::event_y_root()</A></A></h3>
Returns the mouse position on the screen of the event. To find the
absolute position of an <tt>Fl_Window</tt> on the screen, use the
difference between <tt>event_x_root(),event_y_root()</tt> and <tt>
event_x(),event_y()</tt>.
<h3><A name=first_window>static Fl_Window *Fl::first_window()</A></h3>
Returns the first top-level window in the list of shown() windows. If
a modal() window is shown this is the top-most modal window, otherwise
it is the most recent window to get an event.
<h3><A name=next_window>static Fl_Window *Fl::next_window(Fl_Window *)</A></h3>
Returns the next top-level window in the list of shown() windows. You can
use this call to iterate through all the windows that are shown().
<h3>static void Fl::first_window(Fl_Window*)</h3>
Sets the window that is returned by first_window. The window is
removed from wherever it is in the list and inserted at the top. This
is not done if Fl::modal() is on or if the window is not shown().
Because the first window is used to set the "parent" of modal windows,
this is often useful.
<h3><A name=flush>static void Fl::flush()</A></h3>
Causes all the windows that need it to be redrawn and graphics forced
out through the pipes. This is what <tt>wait()</tt> does before
looking for events.
<h3><A name=focus>static Fl_Widget *Fl::focus() const
<br>static void Fl::focus(Fl_Widget *)</A></h3>
Get or set the widget that will receive <tt>FL_KEYBOARD</tt> events.
<P>If you change <tt>Fl::focus()</tt>, the previous widget and all
parents (that don't contain the new widget) are sent <tt>FL_UNFOCUS</tt>
events. Changing the focus does <I>not</I> send <tt>FL_FOCUS</tt> to
this or any widget, because sending <tt>FL_FOCUS</tt> is supposed to <I>
test</I> if the widget wants the focus (by it returning non-zero from <tt>
handle()</tt>).
<h3><A name=foreground>static void Fl::foreground(uchar, uchar, uchar)</A></h3>
Changes <tt>fl_color(FL_BLACK)</tt>. Also changes <tt>
FL_INACTIVE_COLOR</tt> and <tt>FL_SELECTION_COLOR</tt> to be a ramp
between this and <tt>FL_WHITE</tt>.
<h3><A name=free_color>static void Fl::free_color(Fl_Color, int overlay = 0)</A></h3>
Frees the specified color from the colormap, if applicable. If <tt>
overlay</tt> is non-zero then the color is freed from the overlay
colormap.
<h3><A name=get_color>static unsigned Fl::get_color(Fl_Color)
<br>static void Fl::get_color(Fl_Color, uchar &amp;r, uchar &amp;g, uchar &amp;b)</A></h3>
Returns the color index or RGB value for the given FLTK color index.
<h3><A name=get_font>static const char *Fl::get_font(int face)</A></h3>
Get the string for this face. This string is different for each
face. Under X this value is passed to XListFonts to get all the sizes
of this face.
<h3><A name=get_font_name>static const char *Fl::get_font_name(int
face, int *attributes = 0)</A></h3>
Get a human-readable string describing the family of this face. This
is useful if you are presenting a choice to the user. There is no
guarantee that each face has a different name. The return value points
to a static buffer that is overwritten each call.
<P>The integer pointed to by <tt>attributes</tt> (if the pointer is not
zero) is set to zero, <tt>FL_BOLD</tt> or <tt>FL_ITALIC</tt> or <tt>
FL_BOLD | FL_ITALIC</tt>. To locate a &quot;family&quot; of fonts, search
forward and back for a set with non-zero attributes, these faces along
with the face with a zero attribute before them constitute a family.
<h3><A name=get_font_sizes>int get_font_sizes(int face, int *&amp;sizep)</A></h3>
Return an array of sizes in <tt>sizep</tt>. The return value is the
length of this array. The sizes are sorted from smallest to largest
and indicate what sizes can be given to <tt>fl_font()</tt> that will
be matched exactly (<tt>fl_font()</tt> will pick the closest size for
other sizes). A zero in the first location of the array indicates a
scalable font, where any size works, although the array may list sizes
that work &quot;better&quot; than others. Warning: the returned array
points at a static buffer that is overwritten each call. Under X this
will open the display.
<h3><A name=get_mouse>static void Fl::get_mouse(int &amp;x, int &amp;y)</A></h3>
Return where the mouse is on the screen by doing a round-trip query to
the server. You should use <tt>Fl::event_x_root()</tt> and <tt>
Fl::event_y_root()</tt> if possible, but this is necessary if you are
not sure if a mouse event has been processed recently (such as to
position your first window). If the display is not open, this will
open it.
<h3><A name=get_system_colors>static void Fl::get_system_colors()</A></h3>
Read the user preference colors from the system and use them to call
<tt> Fl::foreground()</tt>, <tt>Fl::background()</tt>, and <tt>
Fl::background2()</tt>. This is done by
<tt>Fl_Window::show(argc,argv)</tt> before applying the -fg and -bg
switches.
<P>On X this reads some common values from the Xdefaults database.
KDE users can set these values by running the "krdb" program, and
newer versions of KDE set this automatically if you check the "apply
style to other X programs" switch in their control panel.
<h3><A name=gl_visual>static int Fl::gl_visual(int)</A></h3>
This does the same thing as <A
href=#visual><tt>Fl::visual(int)</tt></A> but also requires OpenGL
drawing to work. This <I>must</I> be done if you want to draw in
normal windows with OpenGL with <A href=opengl.html#gl_start>
<tt>gl_start()</tt></A> and <tt>gl_end()</tt>. It may be useful to
call this so your X windows use the same visual as an <A
href=Fl_Gl_Window.html#Fl_Gl_Window> <tt>Fl_Gl_Window</tt></A>, which
on some servers will reduce colormap flashing.
<P>See <A href=Fl_Gl_Window.html#Fl_Gl_Window.mode><tt>Fl_Gl_Window</tt></A>
for a list of additional values for the argument.
<h3><A name=grab>static void Fl::grab(Fl_Window*)
<br>static Fl_Window* Fl::grab()</A></h3>
This is used when pop-up menu systems are active. Send all events to
the passed window no matter where the pointer or focus is (including
in other programs). The window <I>does not have to be
<tt>shown()</tt></I> , this lets the <tt>handle()</tt> method of a
&quot;dummy&quot; window override all event handling and allows you to
map and unmap a complex set of windows (under both X and WIN32
<I>some</I> window must be mapped because the system interface needs a
window id).
<P>If <tt>grab()</tt> is on it will also affect show() of windows by
doing system-specific operations (on X it turns on
override-redirect). These are designed to make menus popup reliably
and faster on the system.
<P>To turn off grabbing do <tt>Fl::grab(0)</tt>.
<P><I>Be careful that your program does not enter an infinite loop
while <tt>grab()</tt> is on. On X this will lock up your screen!</I>
<h3><A name=h>static int Fl::h()</A></h3>
Returns the height of the screen in pixels.
<h3><A name=handle>static int Fl::handle(int, Fl_Window *)</A></h3>
Sends the event to a window for processing. Returns non-zero if any
widget uses the event.
<h3><A name=help>static const char *Fl::help</A></h3>
This is the usage string that is displayed if <tt>Fl::args()</tt>
detects an invalid argument on the command-line.
<h3><A name=modal>static Fl_Window *Fl::modal()</A></h3>
Returns the top-most <tt>modal()</tt> window currently shown.
This is the most recently <tt>
shown()</tt> window with <A href=Fl_Window.html#Fl_Window.modal><tt>
modal()</tt></A> true, or <tt>NULL</tt> if there are no <tt>modal()</tt>
windows <tt>shown()</tt>.
The <tt>modal()</tt> window has its <tt>handle()</tt> method called
for all events, and no other windows will have <tt>handle()</tt>
called (<A href=#grab><tt>grab()</tt></A> overrides this).
<h3><A name=own_colormap>static void Fl::own_colormap()</A></h3>
Makes FLTK use its own colormap. This may make FLTK display better
and will reduce conflicts with other programs that want lots of colors.
However the colors may flash as you move the cursor between windows.
<P>This does nothing if the current visual is not colormapped.
<h3><A name=paste>static void Fl::paste(Fl_Widget *receiver)</A></h3>
Set things up so the receiver widget will be called with an <A href="enumerations.html#events">
<tt>FL_PASTE</tt></A> event some time in the future. The reciever
should be prepared to be called <I>directly</I> by this, or for it to
happen <I>later</I>, or possibly <I>not at all</I>. This allows the
window system to take as long as necessary to retrieve the paste buffer
(or even to screw up completely) without complex and error-prone
synchronization code in FLTK.
<h3><A name=pushed>static Fl_Widget *Fl::pushed() const
<br>static void Fl::pushed(Fl_Widget *)</A></h3>
Get or set the widget that is being pushed. <tt>FL_DRAG</tt> or <tt>
FL_RELEASE</tt> (and any more <tt>FL_PUSH</tt>) events will be sent to
this widget.
<P>If you change the pushed widget, the previous one and all parents
(that don't contain the new widget) are sent <tt>FL_RELEASE</tt>
events. Changing this does <I>not</I> send <tt>FL_PUSH</tt> to this
or any widget, because sending <tt>FL_PUSH</tt> is supposed to <I>test</I>
if the widget wants the mouse (by it returning non-zero from <tt>
handle()</tt>).
<h3><A name=readqueue>static Fl_Widget *Fl::readqueue()</A></h3>
All <tt>Fl_Widgets</tt> that don't have a callback defined use a
default callback that puts a pointer to the widget in this queue, and
this method reads the oldest widget out of this queue.
<h3><A name=ready>static int Fl::ready()</A></h3>
This is similar to <tt>Fl::check()</tt> except this does <I>not</I>
call <tt>Fl::flush()</tt> or any callbacks, which is useful if your
program is in a state where such callbacks are illegal. This returns
true if <tt>Fl::check()</tt> would do anything (it will continue to
return true until you call <tt>Fl::check()</tt> or <tt>Fl::wait()</tt>).
<ul><pre>while (!calculation_done()) {
calculate();
if (Fl::ready()) {
do_expensive_cleanup();
Fl::check();
if (user_hit_abort_button()) break;
}
}</pre></ul>
<h3><A name=redraw>static void Fl::redraw()</A></h3>
Redraws all widgets.
<h3><A name=has_idle>static int Fl::has_idle(void (*cb)(void*), void* = 0)</A></h3>
Returns true if the specified idle callback is currently installed.
<h3><A name=remove_idle>static void Fl::remove_idle(void (*cb)(void*), void* = 0)</A></h3>
Removes the specified idle callback, if it is installed.
<h3><A name=has_timeout>static int Fl::has_timeout(void (*cb)(void*), void* = 0)</A></h3>
Returns true if the timeout exists and has not been called yet.
<h3><A name=remove_timeout>static void Fl::remove_timeout(void (*cb)(void*), void* = 0)</A></h3>
Removes a timeout callback. It is harmless to remove a timeout
callback that no longer exists.
<h3><A name=has_check>static int Fl::has_check(void (*cb)(void*), void* = 0)</A></h3>
Returns true if the check exists and has not been called yet.
<h3><A name=remove_check>static void Fl::remove_check(void (*cb)(void*), void* = 0)</A></h3>
Removes a check callback. It is harmless to remove a check
callback that no longer exists.
<h3><A name=run>static Fl::run()</A></h3>
As long as any windows are displayed this calls <tt>Fl::wait()</tt>
repeatedly. When all the windows are closed it returns zero
(supposedly it would return non-zero on any errors, but fltk calls
exit directly for these). A normal program will end <tt>main()</tt>
with <tt>return Fl::run();</tt>.
<h3><A name=selection>static void Fl::selection(Fl_Widget *owner, const
char *stuff, int len)
<br>static const char* Fl::selection()
<br>static int Fl::selection_length()</A></h3>
The first form changes the current selection. The block of text is
copied to an internal buffer by FLTK (be careful if doing this in
response to an <tt>FL_PASTE</tt> as this <I>may</I> be the same buffer
returned by <tt>event_text()</tt>). The <tt>selection_owner()</tt>
widget is set to the passed owner (possibly sending <tt>
FL_SELECTIONCLEAR</tt> to the previous owner). The second form looks
at the buffer containing the current selection. The contents of this
buffer are undefined if this program does not own the current
selection.
<h3><A name=selection_owner>static Fl_Widget *Fl::selection_owner() const
<br>static void Fl::selection_owner(Fl_Widget *)</A></h3>
The single-argument <tt>selection_owner(x)</tt> call can be used to
move the selection to another widget or to set the owner to
<tt>NULL</tt>, without changing the actual text of the
selection. <tt>FL_SELECTIONCLEAR</tt> is sent to the previous
selection owner, if any.
<P><I>Copying the buffer every time the selection is changed is
obviously wasteful, especially for large selections. An interface will
probably be added in a future version to allow the selection to be made
by a callback function. The current interface will be emulated on top
of this.</I>
<h3><A name=set_boxtype>static void Fl::set_boxtype(Fl_Boxtype,
Fl_Box_Draw_F *, uchar, uchar, uchar, uchar)
<br>static void Fl::set_boxtype(Fl_Boxtype, Fl_Boxtype from)</A></h3>
The first form sets the function to call to draw a specific boxtype.
<P>The second form copies the <tt>from</tt> boxtype.
<h3><A name=set_color>static void Fl::set_color(Fl_Color, uchar r,
uchar g, uchar b)</A></h3>
Sets an entry in the <tt>fl_color</tt> index table. You can set it to
any 8-bit RGB color. The color is not allocated until <tt>fl_color(i)</tt>
is used.
<h3><A name=set_font>static int Fl::set_font(int face, const char *)
<br>static int Fl::set_font(int face, int from)</A></h3>
The first form changes a face. The string pointer is simply stored,
the string is not copied, so the string must be in static memory.
<P>The second form copies one face to another.
<h3><A name=set_fonts>int Fl::set_fonts(const char * = 0)</A></h3>
FLTK will open the display, and add every font on the server to the
face table. It will attempt to put &quot;families&quot; of faces together, so
that the normal one is first, followed by bold, italic, and bold
italic.
<P>The optional argument is a string to describe the set of fonts to
add. Passing <tt>NULL</tt> will select only fonts that have the
ISO8859-1 character set (and are thus usable by normal text). Passing
&quot;-*&quot; will select all fonts with any encoding as long as they have
normal X font names with dashes in them. Passing &quot;*&quot; will list every
font that exists (on X this may produce some strange output). Other
values may be useful but are system dependent. With WIN32 <tt>NULL</tt>
selects fonts with ISO8859-1 encoding and non-<tt>NULL</tt> selects
all fonts.
<P>The return value is how many faces are in the table after this is
done.
<h3><A name=set_labeltype>static void Fl::set_labeltype(Fl_Labeltype,
Fl_Label_Draw_F *, Fl_Label_Measure_F *)
<br>static void Fl:set_labeltype(Fl_Labeltype, Fl_Labeltype from)</A></h3>
The first form sets the functions to call to draw and measure a
specific labeltype.
<P>The second form copies the <tt>from</tt> labeltype.
<h3><A name=test_shortcut>int Fl::test_shortcut(ulong) const</A></h3>
Test the current event, which must be an <tt>FL_KEYBOARD</tt> or <tt>
FL_SHORTCUT</tt>, against a shortcut value (described in <A href=Fl_Button.html#Fl_Button.shortcut>
<tt>Fl_Button</tt></A>). Returns non-zero if there is a match. Not to
be confused with <A href="subclassing.html#test_shortcut"><tt>
Fl_Widget::test_shortcut()</tt></A>.
<h3><A name=visual>static int Fl::visual(int)</A></h3>
Selects a visual so that your graphics are drawn correctly. This is
only allowed before you call show() on any windows. This does nothing
if the default visual satisfies the capabilities, or if no visual
satisfies the capabilities, or on systems that don't have such
brain-dead notions.
<P>Only the following combinations do anything useful:
<UL>
<LI><tt>Fl::visual(FL_RGB)</tt>
<BR>Full/true color (if there are several depths FLTK chooses the
largest). Do this if you use <A href="drawing.html#fl_draw_image"><tt>fl_draw_image</tt>
</A> for much better (non-dithered) output.
<BR>&nbsp; </LI>
<LI><tt>Fl::visual(FL_RGB8)</tt>
<BR>Full color with at least 24 bits of color. <tt>FL_RGB</tt> will
always pick this if available, but if not it will happily return a
less-than-24 bit deep visual. This call fails if 24 bits are not
available.
<BR>&nbsp; </LI>
<LI><tt>Fl::visual(FL_DOUBLE|FL_INDEX)</tt>
<BR>Hardware double buffering. Call this if you are going to use <A href=Fl_Double_Window.html#Fl_Double_Window>
<tt>Fl_Double_Window</tt></A>.
<BR>&nbsp; </LI>
<LI><tt>Fl::visual(FL_DOUBLE|FL_RGB)</tt></LI>
<LI><tt>Fl::visual(FL_DOUBLE|FL_RGB8)</tt>
<BR>Hardware double buffering and full color.
</UL>
This returns true if the system has the capabilities by default or
FLTK suceeded in turing them on. Your program will still work even if
this returns false (it just won't look as good).
<h3><A name=w>static int Fl::w()</A></h3>
Returns the width of the screen in pixels.
<h3><A name=wait>static int Fl::wait()</a></h3>
Waits until "something happens" and then returns. Call this
repeatedly to "run" your program. You can also check what happened
each time after this returns, which is quite useful for managing
program state.
<P>What this really does is call all idle callbacks, all elapsed
timeouts, call <tt>Fl::flush()</tt> to get the screen to update, and
then wait some time (zero if there are idle callbacks, the shortest of
all pending timeouts, or infinity), for any events from the user or
any <tt>Fl::add_fd()</tt> callbacks. It then handles the events and
calls the callbacks and then returns.
<P>The return value is non-zero if there are any visible windows (this
may change in future versions of fltk).
<h3>static double Fl::wait(double time)</h3>
Same as <tt>Fl::wait()</tt> except it waits a maximum of <i>time</i>
seconds. <i>It can return much sooner if something happens.</i>
<P>The return value is positive if an event or fd happens before the
time elapsed. It is zero if nothing happens (on Win32 this will only
return zero if <i>time</i> is zero). It is negative if an error
occurs (this will happen on Unix if a signal happens).
<h3><A name=warning>static void (*Fl::warning)(const char *, ...)</A>
<br><A name=error>static void (*Fl::error)(const char *, ...)</A>
<br><A name=fatal>static void (*Fl::fatal)(const char *, ...)</A></h3>
FLTK will call these to print messages when unexpected conditions
occur. By default they <tt>fprintf</tt> to <tt>stderr</tt>, and <tt>
Fl::error</tt> and <tt>Fl::fatal</tt> call <tt>exit(1)</tt>. You can
override the behavior by setting the function pointers to your own
routines.
<P><tt>Fl::warning</tt> means that there was a recoverable problem, the
display may be messed up but the user can probably keep working (all X
protocol errors call this). <tt>Fl::error</tt> means there is a
recoverable error, but the display is so messed up it is unlikely the
user can continue (very little calls this now). <tt>Fl::fatal</tt> must
not return, as FLTK is in an unusable state, however your version may
be able to use <tt>longjmp</tt> or an exception to continue, as long as
it does not call FLTK again.
