XInstallColormap(3)			  XLIB FUNCTIONS		      XInstallColormap(3)

NAME
       XInstallColormap, XUninstallColormap, XListInstalledColormaps - control colormaps

SYNTAX
       int XInstallColormap(Display *display, Colormap colormap);

       int XUninstallColormap(Display *display, Colormap colormap);

       Colormap *XListInstalledColormaps(Display *display, Window w, int *num_return);

ARGUMENTS
       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.

DESCRIPTION
       The XInstallColormap function installs the specified colormap for its associated screen.
       All windows associated with this colormap immediately display with true colors.	You asso-
       ciated 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 gener-
       ates 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 gen-
       erates 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.

DIAGNOSTICS
       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.
