 DESCRIPTION

Tk_GeometryRequest is called by widget code to indicate its
preference for the dimensions of a particular window. The arguments
to Tk_GeometryRequest 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 Tk_GeometryRequest, 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
ConfigureNotify event indicating that the geometry change has
occurred. Widget code should never call procedures like
Tk_ResizeWindow directly. Instead, it should invoke
Tk_GeometryRequest and leave the final geometry decisions to
the geometry manager.

If tkwin is a top-level window, then the geometry information
will be passed to the window manager using the standard ICCCM protocol.

Tk_SetInternalBorder 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. Width
specifies the width of the border in pixels. Geometry managers will
use this information to avoid placing any children of tkwin
overlapping the outermost width pixels of tkwin's area.

The information specified in calls to Tk_GeometryRequest and
Tk_SetInternalBorder can be retrieved using the macros
Tk_ReqWidth, Tk_ReqHeight, and Tk_InternalBorderWidth.
See the Tk_WindowId manual entry for details.
