B<Tk_DefineCursor>(I<tkwin, cursor>)
B<Tk_UndefineCursor>(I<tkwin>)
=head1 ARGUMENTS
=over 4
=item Tk_Window tkwin (in)
Token for window.
=item "unsigned int" valueMask (in)
OR-ed mask of values like B<CWX> or B<CWBorderPixel>,
indicating which fields of I<*valuePtr> or I<*attsPtr> to use.
=item XWindowChanges *valuePtr (in)
Points to a structure containing new values for the configuration
parameters selected by I<valueMask>. Fields not selected
by I<valueMask> are ignored.
=item int x (in)
New x-coordinate for I<tkwin>'s top left pixel (including
border, if any) within tkwin's parent.
=item int y (in)
New y-coordinate for I<tkwin>'s top left pixel (including
border, if any) within tkwin's parent.
=item "int" width (in)
New width for I<tkwin> (interior, not including border).
=item "int" height (in)
New height for I<tkwin> (interior, not including border).
=item "int" borderWidth (in)
New width for I<tkwin>'s border.
=item XSetWindowAttributes *attsPtr (in)
Points to a structure containing new values for the attributes
given by the I<valueMask> argument. Attributes not selected
by I<valueMask> are ignored.
=item "unsigned long" pixel (in)
New background or border color for window.
=item Pixmap pixmap (in)
New pixmap to use for background or border of I<tkwin>. WARNING:
cannot necessarily be deleted immediately, as for Xlib calls. See
note below.
=item Colormap colormap (in)
New colormap to use for I<tkwin>.
=item Tk_Cursor cursor (in)
New cursor to use for I<tkwin>. If B<None> is specified, then
I<tkwin> will not have its own cursor; it will use the cursor
of its parent.

=head1 DESCRIPTION
These procedures are analogous to the X library procedures
with similar names, such as B<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 B<Tk_X> and B<Tk_Height>) without having to contact
the X server. In addition, if no X window has actually been
created for I<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 B<Tk_ConfigureWindow>, B<Tk_MoveWindow>,
B<Tk_ResizeWindow>, B<Tk_MoveResizeWindow>, and
B<Tk_SetWindowBorderWidth>,
if I<tkwin> is an internal window then event handlers interested
in configure events are invoked immediately, before the procedure
returns. If I<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
B<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 L<Tk::MoveToplev> for moving a top-level
window).
You may not use B<Tk_ConfigureWindow> to change the
stacking order of a window (I<valueMask> may not contain the
B<CWSibling> or B<CWStackMode> bits).
To change the stacking order, use the procedure B<Tk_RestackWindow>.
The procedure B<Tk_SetWindowColormap> will automatically add
I<tkwin> to the B<TK_COLORMAP_WINDOWS> property of its
nearest top-level ancestor if the new colormap is different from
that of I<tkwin>'s parent and I<tkwin> isn't already in
the B<TK_COLORMAP_WINDOWS> property.
=head1 BUGS
B<Tk_SetWindowBackgroundPixmap> and B<Tk_SetWindowBorderPixmap>
differ slightly from their Xlib counterparts in that the I<pixmap>
argument may not necessarily be deleted immediately after calling
one of these procedures. This is because I<tkwin>'s window
may not exist yet at the time of the call, in which case I<pixmap>
is merely saved and used later when I<tkwin>'s window is actually
created. If you wish to delete I<pixmap>, then call
B<Tk_MakeWindowExist> first to be sure that I<tkwin>'s window exists
and I<pixmap> has been passed to the X server.
A similar problem occurs for the I<cursor> argument passed to
B<Tk_DefineCursor>. The solution is the same as for pixmaps above:
call B<Tk_MakeWindowExist> before freeing the cursor.
