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 CWBor-
derPixel,
indicating
which fields
of *valuePtr
or *attsPtr
to use.
XWindowChanges *valuePtr (in) Points to a
structure
containing
new values
for the con-
figuration
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 (inte-
rior, 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 back-
ground or
border color
for window.
Pixmap pixmap (in) New pixmap to
use for back-
ground or
border of
tkwin. WARN-
ING: 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 cur-
sor; it will
use the cur-
sor 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 informa-
tion in Tk's local structure for the window; when the win-
dow 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 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 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.
