XtSetWMColormapWindows() XtSetWMColormapWindows()
Name
XtSetWMColormapWindows - set WM_COLORMAP_WINDOWS property to inform window manager of custom colormaps.
Synopsis
void XtSetWMColormapWindows(widget, list, count)
Widget widget;
Widget* list;
Cardinal count;
Inputs
widget Specifies the widget on whose window the WM_COLORMAP_WINDOWS property will be stored. Must be of class Core or any subclass
thereof.
list Specifies a list of widgets whose windows are to be listed in the WM_COLORMAP_WINDOWS property.
count Specifies the number of widgets in list.
Availability
Release 4 and later.
Description
XtSetWMColormapWindows() returns immediately if widget is not realized or if count is 0. Otherwise, XtSetWMColormapWindows() constructs an
ordered list of windows by examining each widget in the list in turn and:
o Ignoring the widget if it is not realized or
o Adding the widget's window to the window list if the widget is realized and if its colormap resource differs from the colormap resources
of all widgets whose windows are already on the window list.
Finally, XtSetWMColormapWindows() stores the resulting window list in the WM_COLORMAP_WINDOWS property on the specified widget's window.
This tells the window manager which windows have a custom colormap, so that the window manager can install these colormaps at the appropri-
ate time.
See section 4.1.8 of the Inter-Client Communications Conventions Manual for details on the meaning of the WM_COLORMAP_WINDOWS property.
Usage
Only applications that make sophisticated use of color and use multiple colormaps will ever need to call this function.

Description
The function replaces the WM_COLORMAP_WINDOWS property on the specified window with the list of windows specified by the colormap_windows
argument. It the property does not already exist, sets the WM_COLORMAP_WINDOWS property on the specified window to the list of windows
specified by the colormap_windows argument. The property is stored with a type of WINDOW and a format of 32. If it cannot intern the
WM_COLORMAP_WINDOWS atom, returns a zero status. Otherwise, it returns a non-zero status.
can generate and errors.
The function returns the list of window identifiers stored in the WM_COLORMAP_WINDOWS property on the specified window. These identifiers
indicate the colormaps that the window manager may need to install for this window. If the property exists, is of type WINDOW, is of for-
mat 32, and the atom WM_COLORMAP_WINDOWS can be interned, sets the windows_return argument to a list of window identifiers, sets the
count_return argument to the number of elements in list, and returns a non-zero status. Otherwise, it sets neither of the return arguments
and returns a zero status. To release the list of window identifiers, use
can generate a error.
Properties
WM_COLORMAP_WINDOWS
List of window IDs that may need a different colormap than that of their top-level window.
Diagnostics
The server failed to allocate the requested resource or server memory.
