<H3>Description</H3>
|
|
|
|
<P>This is a virtual base class below <A
|
|
href="Fl_Input.html#Fl_Input"><TT>Fl_Input</TT></A>. It has all
|
|
the same interfaces, but lacks the <TT>handle()</TT> and
|
|
<TT>draw()</TT> method. You may want to subclass it if you are
|
|
one of those people who likes to change how the editing keys
|
|
work.
|
|
|
|
<P>This can act like any of the subclasses of Fl_Input, by
|
|
setting <TT>type()</TT> to one of the following values:</P>

<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>
|
|
|
|
<P>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>
|
|
|
|
<P>The destructor removes the widget and any value associated with it.
|
|
|
|
<H4><A name="Fl_Input_.wordboundary">int Fl_Input_::wordboundary(int i)
|
|
const</A></H4>
|
|
|
|
<P>Returns true if position <TT>i</TT> is at the start or end of a word.
|
|
|
|
<H4><A name="Fl_Input_.lineboundary">int Fl_Input_::lineboundary(int i)
|
|
const</A></H4>
|
|
|
|
<P>Returns true if position <TT>i</TT> is at the start or end of a line.
|
|
|
|
<H4><A name="Fl_Input_.drawtext">void Fl_Input_::drawtext(int,int,int,int)</A></H4>
|
|
|
|
<P>Draw the text in the passed bounding box. If <TT>damage()
|
|
& FL_DAMAGE_ALL</TT> is true, this assumes the area has
|
|
already been erased to <TT>color()</TT>. Otherwise it does
|
|
minimal update and erases the area itself.
|
|
|
|
<H4><A name="Fl_Input_.handletext">int Fl_Input_::handletext(int
|
|
e,int,int,int,int)</A></H4>
|
|
|
|
<P>Default handler for all event types. Your <TT>handle()</TT>
|
|
method should call this for all events that it does not handle
|
|
completely. You must pass it the same bounding box as you do
|
|
when calling <TT>drawtext()</TT> from your <tt>draw()</tt>
|
|
method. Handles <TT>FL_PUSH</TT>, <TT>FL_DRAG</TT>,
|
|
<TT>FL_RELEASE</TT> to select text, handles <TT>FL_FOCUS</TT>
|
|
and <TT>FL_UNFOCUS</TT> to show and hide the cursor.
|
|
|
|
<H4><A name="Fl_Input_.up_down_position">int
|
|
Fl_Input_::up_down_position(int i, int keepmark=0)</A></H4>
|
|
|
|
<P>Do the correct thing for arrow keys. Sets the position (and
|
|
mark if <I>keepmark</I> is zero) to somewhere in the same line
|
|
as <I>i</I>, such that pressing the arrows repeatedly will cause
|
|
the point to move up and down.
|
|
|
|
<H4><A name="Fl_Input_.maybe_do_callback">void
|
|
Fl_Input_::maybe_do_callback()</A></H4>
|
|
|
|
<P>Does the callback if <TT>changed()</TT> is true or if
|
|
<TT>when() & FL_WHEN_NOT_CHANGED</TT> is non-zero. You
|
|
should call this at any point you think you should generate a
|
|
callback.
|
|
|
|
<H4><A name="Fl_Input_.maximum_size">void Fl_Input_::maximum_size(int m)<BR>
|
|
int Fl_Input_::maximum_size() const</A></H4>
|
|
|
|
<P>Sets or returns the maximum length of the input field.
|
|
|
|
<H4><A name="Fl_Input_.position">int Fl_Input_::position() const
|
|
<BR>int Fl_Input_::position(int new_position, int new_mark)
|
|
<BR>int Fl_Input_::position(int new_position_and_new_mark)</A></H4>
|
|
|
|
<P>The input widget maintains two pointers into the string. The
|
|
"position" is where the cursor is. The
|
|
"mark" is the other end of the selected text. If they
|
|
are equal then there is no selection. Changing this does not
|
|
affect the clipboard (use <TT>copy()</TT> to do that).
|
|
|
|
<P>Changing these values causes a <TT>redraw()</TT>. The new
|
|
values are bounds checked. The return value is non-zero if the
|
|
new position is different than the old one. <TT>position(n)</TT>
|
|
is the same as <TT>position(n,n)</TT>. <TT>mark(n)</TT> is the
|
|
same as <TT>position(position(),n)</TT>.</P>
|
|
|
|
<H4><A name="Fl_Input_.mark">int Fl_Input_::mark() const
|
|
<BR> int Fl_Input_::mark(int new_mark)</A></H4>
|
|
|
|
<P>Gets or sets the current selection mark. <TT>mark(n)</TT> is
|
|
the same as <TT>position(position(),n)</TT>.
|
|
|
|
<H4><A name="Fl_Input_.replace">int Fl_Input_::replace(int a, int b,
|
|
const char *insert, int length=0)</A></H4>
|
|
|
|
<P>This call does all editing of the text. It deletes the region
|
|
between <TT>a</TT> and <TT>b</TT> (either one may be less or
|
|
equal to the other), and then inserts the string <TT>insert</TT>
|
|
at that point and leaves the <TT>mark()</TT> and
|
|
<TT>position()</TT> after the insertion. Does the callback if
|
|
<TT>when() & FL_WHEN_CHANGED</TT> and there is a change.
|
|
|
|
<P>Set <TT>start</TT> and <TT>end</TT> equal to not delete
|
|
anything. Set <TT>insert</TT> to <TT>NULL</TT> to not insert
|
|
anything.</P>
|
|
|
|
<P><TT>length</TT> must be zero or <TT>strlen(insert)</TT>, this
|
|
saves a tiny bit of time if you happen to already know the
|
|
length of the insertion, or can be used to insert a portion of a
|
|
string or a string containing nul's.</P>
|
|
|
|
<P><TT>a</TT> and <TT>b</TT> are clamped to the
|
|
0..<TT>size()</TT> range, so it is safe to pass any values.</P>
|
|
|
|
<P><TT>cut()</TT> and <TT>insert()</TT> are just inline
|
|
functions that call <TT>replace()</TT>.</P>
|
|
|
|
<H4><A name="Fl_Input_.cut">int Fl_Input_::cut()
|
|
<BR> int Fl_Input_::cut(int n)
|
|
<BR> int Fl_Input_::cut(int a, int b);</A></H4>
|
|
|
|
<P><TT>Fl_Input_::cut()</TT> deletes the current selection.
|
|
<TT>cut(n)</TT> deletes <TT>n</TT> characters after the
|
|
<TT>position()</TT>. <TT>cut(-n)</TT> deletes <TT>n</TT>
|
|
characters before the <TT>position()</TT>. <TT>cut(a,b)</TT>
|
|
deletes the characters between offsets <TT>a</TT> and
|
|
<TT>b</TT>. <TT>A</TT>, <TT>b</TT>, and <TT>n</TT> are all
|
|
clamped to the size of the string. The mark and point are left
|
|
where the deleted text was.
|
|
|
|
<P>If you want the data to go into the clipboard, do
|
|
<TT>Fl_Input_::copy()</TT> before calling
|
|
<TT>Fl_Input_::cut()</TT>, or do <TT>Fl_Input_::copy_cuts()</TT>
|
|
afterwards.</P>
|
|
|
|
<H4><A name="Fl_Input_.insert">int Fl_Input_::insert(const char *t,int
|
|
l=0)</A></H4>
|
|
|
|
<P>Insert the string <TT>t</TT> at the current position, and
|
|
leave the mark and position after it. If <TT>l</TT> is not zero
|
|
then it is assumed to be <TT>strlen(t)</TT>.
|
|
|
|
<H4><A name="Fl_Input_.copy">int Fl_Input_::copy(int clipboard)</A></H4>
|
|
|
|
<P>Put the current selection between <TT>mark()</TT> and
|
|
<TT>position()</TT> into the specified clipboard. Does not
|
|
replace the old clipboard contents if <TT>position()</TT> and
|
|
<TT>mark()</TT> are equal. Clipboard 0 maps to the current text
|
|
selection and clipboard 1 maps to the cut/paste clipboard.
|
|
|
|
<H4><A name="Fl_Input_.undo">int Fl_Input_::undo()</A></H4>
|
|
|
|
<P>Does undo of several previous calls to <TT>replace()</TT>.
|
|
Returns non-zero if any change was made.
|
|
|
|
<H4><A name="Fl_Input_.copy_cuts">int Fl_Input_::copy_cuts()</A></H4>
|
|
|
|
<P>Copy all the previous contiguous cuts from the undo
|
|
information to the clipboard. This is used to make ^K work.
|
|
|
|
<H4><A name="Fl_Input_.input_type">int Fl_Input_::input_type() const
|
|
<BR>void Fl_Input_::input_type(int)</A></H4>
|
|
|
|
<P>Gets or sets the input field type.
|
|
|
|
<H4><A name="Fl_Input_.readonly">int Fl_Input_::readonly() const
|
|
<BR>void Fl_Input_::readonly(int)</A></H4>
|
|
|
|
<P>Gets or sets the read-only state of the input field.
|
|
|
|
<H4><A name="Fl_Input_.wrap">int Fl_Input_::wrap() const
|
|
<BR>void Fl_Input_::wrap(int)</A></H4>
|
|
|
|
<P>Gets or sets the word wrapping state of the input field. Word
|
|
wrap is only functional with multi-line input fields.
