show tooltips for box widgets. Add docos for Fl_Widget::tooltip() methods. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@2060 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

CHANGES IN FLTK 1.1.0b13
|
||||
|
||||
- Tooltips now appear for inactive and output widgets.
|
||||
- Tooltips no longer steal keyboard events other than
|
||||
ESCape.
|
||||
- Tooltips are no longer delayed when moving between
|
||||
adjacent widgets.
|
||||
- fl_beep(FL_BEEP_DEFAULT) now uses the PC speaker under
|
||||
Windows (0xFFFFFFFF) rather than an event sound.
|
||||
- The configure script didn't include the -mwindows or

The <TT>box()</TT> identifies a routine that draws the background of

FL_NO_BOX</TT> or <TT>FL_UP_BOX</TT>.

<P>Gets or sets the box type for the widget, which identifies a

routine that draws the background of the widget. See <A

This color is passed to the box routine. Color is an index into an

internal table of rgb colors. For most widgets this defaults to <TT>
|

FL_GRAY</TT>. See the <A href=enumerations.html#Enumerations>

|

|

<P>Gets or sets the background color of the widget. The color is
|
||||
passed to the box routine. The color is either an index into an
|
||||
internal table of RGB colors or an RGB color value generated
|
||||
using <TT>fl_rgb_color()</TT>. The default for most widgets is
|
||||
<TT>FL_GRAY</TT>. See the <A

href=enumerations.html#Enumerations>enumeration list</A> for
|
||||
predefined colors. Use <A

|
||||
redefine colors.
|
||||
|

<P>The two color form sets both the background and selection
|

colors. See the description of the <A

|

For Forms compatibility a second color is defined. This is usually
|
||||
used to color the widget when it is selected, although some widgets use
|
||||
this color for other purposes. You can set both colors at once with <TT>
|

color(a,b)</TT>.

<P>Gets or sets the selection color, which is defined for Forms
|

compatibility and is usually used to color the widget when it is

selected, although some widgets use this color for other

purposes. You can set both colors at once with

<H4><A name=Fl_Widget.label>const char* Fl_Widget::label() const

The label is printed somewhere on the widget or next to it. The

string is <I>not</I> copied, the passed pointer is stored unchanged in
|
||||
the widget.
|
||||
|

<P>Get or set the current label pointer. The label is shown
|

somewhere on or next to the widget. The passed pointer is stored
|

unchanged in the widget (the string is <I>not</I> copied), so if
|

you need to set the label to a formatted value, make sure the
|

buffer is <TT>static</TT>, global, or allocated.

|
||||
A <A href="common.html#labeltypes"><TT>labeltype</TT></A> identifies a routine that
|
||||
draws the label of the widget. This can be used for special effects
|
||||
such as emboss, or to use the <TT>label()</TT> pointer as another form
|
||||
of data such as a bitmap. The value <TT>FL_NORMAL_LABEL</TT> prints
|
||||
the label as text.
|
||||
|
||||
<P>Gets or sets the <A
|
||||
href="common.html#labeltypes"><TT>labeltype</TT></A> which
|
||||
identifies the function that draws the label of the widget. This
|
||||
is generally used for special effects such as embossing or for
|
||||
using the <TT>label()</TT> pointer as another form of data such
|
||||
as an icon. The value <TT>FL_NORMAL_LABEL</TT> prints the label
|
||||
as plain text.

|

How the label is printed next to or inside the widget. The default
|

value is <TT>FL_ALIGN_CENTER</TT>, which centers the label. The value
|
||||
can be any of these constants or'd together:
|
||||
|

<P>Gets or sets the label alignment, which controls how the

label is displayed next to or inside the widget. The default

inside the widget. The value can be any of these constants
