NAME

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

SYNOPSIS

       #include <tk.h>

       Tk_GeometryRequest(tkwin, reqWidth, reqHeight)

       Tk_SetMinimumRequestSize(tkwin, minWidth, minHeight)

       Tk_SetInternalBorder(tkwin, width)

       Tk_SetInternalBorderEx(tkwin, left, right, top, bottom)

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 minWidth (in)		   Desired minimum requested width for tkwin, in pixel units.

       int minHeight (in)		   Desired minimum requested height for tkwin, in pixel units.

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

       int left (in)			   Space to leave for left side of internal border for tkwin, in pixel units.

       int right (in)			   Space to leave for right side of internal border for tkwin, in pixel units.

       int top (in)			   Space to leave for top side of internal border for tkwin, in pixel units.

       int bottom (in)			   Space to leave for bottom side of 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 deco-
       rative 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_Internal-
       BorderRight, Tk_InternalBorderTop and Tk_InternalBorderBottom.  See the Tk_WindowId manual entry for details.
