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.
