    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_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  Con-
         figureNotify  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  informa-
         tion 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 outer-
         most 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.
