XInstallColormap 3X11 __xorgversion__ XLIB FUNCTIONS XInstallColormap XUninstallColormap XListInstalledColormaps control colormaps int XInstallColormap ( Display *display , Colormap colormap ); int XUninstallColormap ( Display *display , Colormap colormap ); Colormap *XListInstalledColormaps ( Display *display , Window w , int *num_return ); colormap Specifies the colormap. display Specifies the connection to the X server. num_return Returns the number of currently installed colormaps. w Specifies the window that determines the screen. The  XInstallColormap  function installs the specified colormap for its associated screen. All windows associated with this colormap immediately display with true colors. You associated the windows with this colormap when you created them by calling  XCreateWindow ,  XCreateSimpleWindow ,  XChangeWindowAttributes , or  XSetWindowColormap . If the specified colormap is not already an installed colormap, the X server generates a  ColormapNotify  event on each window that has that colormap. In addition, for every other colormap that is installed as a result of a call to  XInstallColormap , the X server generates a  ColormapNotify  event on each window that has that colormap.  XInstallColormap  can generate a  BadColor  error. The  XUninstallColormap  function removes the specified colormap from the required list for its screen. As a result, the specified colormap might be uninstalled, and the X server might implicitly install or uninstall additional colormaps. Which colormaps get installed or uninstalled is server dependent except that the required list must remain installed. If the specified colormap becomes uninstalled, the X server generates a  ColormapNotify  event on each window that has that colormap. In addition, for every other colormap that is installed or uninstalled as a result of a call to  XUninstallColormap , the X server generates a  ColormapNotify  event on each window that has that colormap.  XUninstallColormap  can generate a  BadColor  error. The  XListInstalledColormaps  function returns a list of the currently installed colormaps for the screen of the specified window. The order of the colormaps in the list is not significant and is no explicit indication of the required list. When the allocated list is no longer needed, free it by using  XFree .  XListInstalledColormaps  can generate a  BadWindow  error.  BadColor  A value for a Colormap argument does not name a defined Colormap.  BadWindow  A value for a Window argument does not name a defined Window.
