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.
Tk_SetInternalBorderEx works like
Tk_SetInternalBorder but lets you specify different widths
for different sides of the window.
Tk_SetMinimumRequestSize is called by widget code to
indicate that a geometry manager should request at least this size
for the widget. This allows a widget to have some control over its
size when a propagating geometry manager is used inside it.
The information specified in calls to Tk_GeometryRequest,
Tk_SetMinimumRequestSize, Tk_SetInternalBorder and
Tk_SetInternalBorderEx can be retrieved using the macros
Tk_ReqWidth, Tk_ReqHeight, Tk_MinReqWidth, Tk_MinReqHeight, Tk_MinReqWidth, Tk_InternalBorderLeft, Tk_InternalBorderRight, Tk_InternalBorderTop and
Tk_InternalBorderBottom.

manual entry for details.
