XtSetWMColormapWindows - Set the value of the WM_COLORMAP_WINDOWS prop- erty
#include <X11/Intrinsic.h> void XtSetWMColormapWindows(Widget widget, Widget* list, Cardinal count);
widget Specifies the widget on whose window the WM_COLORMAP_WINDOWS property will be stored. Must be of class Core or any sub- class thereof. list Specifies a list of widgets whose windows are are potentially to be listed in the WM_COLORMAP_WINDOWS property. count Specifies the number of widgets in list.
XtSetWMColormapWindows returns immediately if widget is not realized or if count is zero. Otherwise, XtSetWMColormapWindows constructs an ordered list of windows by examining each widget in list in turn and ignoring the widget if it is not realized, or adding the widget's win- dow to the window list if the widget is realized and its colormap resource is different 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.
