 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 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.
