- .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.
