XGetWMColormapWindows(3)


NAME

   XSetWMColormapWindows, XGetWMColormapWindows - set or read a window's
   WM_COLORMAP_WINDOWS property

SYNTAX

   Status XSetWMColormapWindows(Display *display, Window w, Window
          *colormap_windows, int count);

   Status XGetWMColormapWindows(Display *display, Window w, Window
          **colormap_windows_return, int *count_return);

ARGUMENTS

   display   Specifies the connection to the X server.

   colormap_windows
             Specifies the list of windows.

   colormap_windows_return
             Returns the list of windows.

   count     Specifies the number of windows in the list.

   count_return
             Returns the number of windows in the list.

   w         Specifies the window.

DESCRIPTION

   The XSetWMColormapWindows 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,
   XSetWMColormapWindows 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, XSetWMColormapWindows returns a zero status.  Otherwise, it
   returns a nonzero status.

   XSetWMColormapWindows can generate BadAlloc and BadWindow errors.

   The XGetWMColormapWindows 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 format 32, and the atom WM_COLORMAP_WINDOWS
   can be interned, XGetWMColormapWindows sets the windows_return argument
   to a list of window identifiers, sets the count_return argument to the
   number of elements in the list, and returns a nonzero status.
   Otherwise, it sets neither of the return arguments and returns a zero
   status.  To release the list of window identifiers, use XFree.

   XGetWMColormapWindows can generate a BadWindow error.

PROPERTIES

   WM_COLORMAP_WINDOWS
             The list of window IDs that may need a different colormap
             from that of their top-level window.

DIAGNOSTICS

   BadAlloc  The server failed to allocate the requested resource or
             server memory.

   BadWindow A value for a Window argument does not name a defined Window.
