XInstallColormap(3X11)  COMMAND REFERENCE  XInstallColormap(3X11)



NAME
     XInstallColormap, XUninstallColormap,
     XListInstalledColormaps - control colormaps

SYNOPSIS
     XInstallColormap(display, colormap)
           Display *display;
           Colormap colormap;

     XUninstallColormap(display, colormap)
           Display *display;
           Colormap colormap;

     Colormap *XListInstalledColormaps(display, w, num_return)
           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 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.

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.
