                                                      immediately, as for Xlib

DESCRIPTION

       These procedures are analogous to the X library procedures with similar
       names, such as XConfigureWindow.  Each  one  of  the  above  procedures
       calls  the  corresponding  X procedure and also saves the configuration
       information in Tk's local structure for the window.   This  allows  the
       information  to  be  retrieved quickly by the application (using macros
       such as Tk_X and Tk_Height) without having to contact the X server.  In
       addition, if no X window has actually been created for tkwin yet, these
       procedures do not issue X operations or  cause  event  handlers  to  be
       invoked;   they  save  the  information in Tk's local structure for the
       window;  when the window is created later, the saved  information  will
       be used to configure the window.

       See the X library documentation for details on what these procedures do
       and how they use their arguments.

       In the procedures Tk_ConfigureWindow,  Tk_MoveWindow,  Tk_ResizeWindow,
       Tk_MoveResizeWindow, and Tk_SetWindowBorderWidth, if tkwin is an inter-
       nal window then event  handlers  interested  in  configure  events  are
       invoked  immediately, before the procedure returns.  If tkwin is a top-
       level window then the event handlers will be invoked later, after X has
       seen the request and returned an event for it.

       Applications  using Tk should never call procedures like XConfigureWin-
       dow directly;  they should always use the corresponding Tk  procedures.

       The size and location of a window should only be modified by the appro-
       priate geometry manager for that window and never by  a  window  itself
       (but see Tk_MoveToplevelWindow for moving a top-level window).

       You  may  not  use Tk_ConfigureWindow to change the stacking order of a
       window (valueMask may not contain the CWSibling or  CWStackMode  bits).
       To change the stacking order, use the procedure Tk_RestackWindow.

       The  procedure Tk_SetWindowColormap will automatically add tkwin to the
       TK_COLORMAP_WINDOWS property of its nearest top-level ancestor  if  the
       new  colormap  is different from that of tkwin's parent and tkwin isn't
       already in the TK_COLORMAP_WINDOWS property.


BUGS

       Tk_SetWindowBackgroundPixmap   and   Tk_SetWindowBorderPixmap    differ
       slightly  from  their Xlib counterparts in that the pixmap argument may
       not necessarily be deleted immediately after calling one of these  pro-
       cedures.   This is because tkwin's window may not exist yet at the time
       of the call, in which case pixmap is merely saved and used  later  when
       tkwin's window is actually created.  If you wish to delete pixmap, then
       call Tk_MakeWindowExist first to be sure that tkwin's window exists and
       pixmap has been passed to the X server.

       A   similar   problem   occurs   for  the  cursor  argument  passed  to
       Tk_DefineCursor.  The solution is the same as for pixmaps  above:  call
       Tk_MakeWindowExist before freeing the cursor.
