XSetWMColormapWindows(3X11) XSetWMColormapWindows(3X11) NAME XSetWMColormapWindows, XGetWMColormapWindows - set or read a window's WM_COLORMAP_WINDOWS property SYNOPSIS Status XSetWMColormapWindows(display, w, colormap_windows, count) Display *display; Window w; Window *colormap_windows; int count; Status XGetWMColormapWindows(display, w, colormap_windows_return, count_return) Display *display; Window w; Window **colormap_windows_return; int *count_return; ARGUMENTS Specifies the connection to the X server. Specifies the list of win- dows. Returns the list of windows. Specifies the number of windows in the list. Returns the number of windows in the list. 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_win- dows argument. The property is stored with a type of WINDOW and a for- mat of 32. If it cannot intern the WM_COLORMAP_WINDOWS atom, XSetWM- ColormapWindows 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 identi- fiers stored in the WM_COLORMAP_WINDOWS property on the specified win- dow. 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 in- terned, XGetWMColormapWindows sets the windows_return argument to a list of window identifiers, sets the count_return argument to the num- ber 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 The 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. A value for a Window argument does not name a defined Window.
