______________________________________________________________________________

NAME
       Tk_GeometryRequest,  Tk_SetInternalBorder - specify desired geometry or
       internal	border for a window

SYNOPSIS
       #include	<tk.h>

       Tk_GeometryRequest(tkwin, reqWidth, reqHeight)

       Tk_SetInternalBorder(tkwin, width)

ARGUMENTS
       Tk_Window    tkwin	 (in)	   Window for which geometry is	 being
					   requested.

       int	    reqWidth	 (in)	   Desired  width  for tkwin, in pixel
					   units.

       int	    reqHeight	 (in)	   Desired height for tkwin, in	 pixel
					   units.

       int	    width	 (in)	   Space  to leave for internal	border
					   for tkwin, in pixel units.

DESCRIPTION
       Tk_GeometryRequest is called by widget code to indicate its  preference
       for  the	dimensions of a	particular window.  The	arguments to Tk_Geome-
       tryRequest are made available to	the geometry manager for  the  window,
       which then decides on the actual	geometry for the window.  Although ge-
       ometry managers generally try to	satisfy	 requests  made	 to  Tk_Geome-
       tryRequest,  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 wid-
       get has an internal border.  This means that the	widget draws a decora-
       tive  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	 plac-
       ing any children	of tkwin overlapping the outermost width pixels	of tk-
       win's area.

       The information specified in calls to  Tk_GeometryRequest  and  Tk_Set-
       InternalBorder  can  be	retrieved using	the macros Tk_ReqWidth,	Tk_Re-
       qHeight,	and Tk_InternalBorderWidth.  See the Tk_WindowId manual	 entry
       for details.
