       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.
