       Tk_ChangeWindowAttributes(tkwin, valueMask, attsPtr)

       Tk_SetWindowBackground(tkwin, pixel)

       Tk_SetWindowBorder(tkwin, pixel)

       Tk_SetWindowBorderPixmap(tkwin, pixmap)

       Tk_SetWindowColormap(tkwin, colormap)

       Tk_DefineCursor(tkwin, cursor)

       Tk_UndefineCursor(tkwin)

ARGUMENTS

Tk_Window tkwin (in) Token for window.

unsigned int valueMask (in) OR-ed mask of values like CWX or CWBorderPixel, indicating
which fields of *valuePtr or *attsPtr to use.

XWindowChanges *valuePtr (in) Points to a structure containing new values for the
configuration parameters selected by valueMask. Fields
not selected by valueMask are ignored.

int x (in) New x-coordinate for tkwin's top left pixel (including
border, if any) within tkwin's parent.

int y (in) New y-coordinate for tkwin's top left pixel (including
border, if any) within tkwin's parent.

int width (in) New width for tkwin (interior, not including border).

int height (in) New height for tkwin (interior, not including border).

int borderWidth (in) New width for tkwin's border.

XSetWindowAttributes *attsPtr (in) Points to a structure containing new values for the
attributes given by the valueMask argument. Attributes
not selected by valueMask are ignored.

unsigned long pixel (in) New background or border color for window.

Pixmap pixmap (in) New pixmap to use for background or border of tkwin.
WARNING: cannot necessarily be deleted immediately, as for
Xlib calls. See note below.

Colormap colormap (in) New colormap to use for tkwin.

Tk_Cursor cursor (in) New cursor to use for tkwin. If None is specified, then
tkwin will not have its own cursor; it will use the
cursor of its parent.

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 internal 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 XConfigureWindow directly; they should always
use the corresponding Tk procedures.

The size and location of a window should only be modified by the appropriate 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 is
not 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
       procedures.   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.
