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.
