.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
\fBTk_GeometryRequest\fR is called by widget code to indicate its
|
||
|
|
preference for the dimensions of a particular window. The arguments
|
||
|
|
to \fBTk_GeometryRequest\fR are made available to the geometry
|
||
|
|
manager for the window, which then decides on the actual geometry
|
||
|
|
for the window. Although geometry managers generally try to satisfy
|
||
|
|
requests made to \fBTk_GeometryRequest\fR, there is no guarantee that
|
||
|
|
this will always be possible. Widget code should not assume that
|
||
|
|
a geometry request will be satisfied until it receives a
|
||
|
|
\fBConfigureNotify\fR event indicating that the geometry change has
|
||
|
|
occurred. Widget code should never call procedures like
|
||
|
|
\fBTk_ResizeWindow\fR directly. Instead, it should invoke
|
||
|
|
\fBTk_GeometryRequest\fR and leave the final geometry decisions to
|
||
|
|
the geometry manager.
|
||
|
|
.PP
|
||
|
|
If \fItkwin\fR is a top-level window, then the geometry information
|
||
|
|
will be passed to the window manager using the standard ICCCM protocol.
|
||
|
|
.PP
|
||
|
|
\fBTk_SetInternalBorder\fR is called by widget code to indicate that
|
||
|
|
the widget has an internal border. This means that the widget draws
|
||
|
|
a decorative border inside the window instead of using the standard
|
||
|
|
X borders, which are external to the window's area. For example,
|
||
|
|
internal borders are used to draw 3-D effects. \fIWidth\fR
|
||
|
|
specifies the width of the border in pixels. Geometry managers will
|
||
|
|
use this information to avoid placing any children of \fItkwin\fR
|
||
|
|
overlapping the outermost \fIwidth\fR pixels of \fItkwin\fR's area.
|
||
|
|
.PP
|
||
|
|
The information specified in calls to \fBTk_GeometryRequest\fR and
|
||
|
|
\fBTk_SetInternalBorder\fR can be retrieved using the macros
|
||
|
|
\fBTk_ReqWidth\fR, \fBTk_ReqHeight\fR, and \fBTk_InternalBorderWidth\fR.
|
||
|
|
See the \fBTk_WindowId\fR manual entry for details.
