DESCRIPTION

28       The XInstallColormap function installs the specified colormap for its
29       associated screen.  All windows associated with this colormap immedi‐
30       ately display with true colors.  You associated the windows with this
31       colormap when you created them by calling XCreateWindow, XCreateSim‐
32       pleWindow, XChangeWindowAttributes, or XSetWindowColormap.
33
34       If the specified colormap is not already an installed colormap, the X
35       server generates a ColormapNotify event on each window that has that
36       colormap.  In addition, for every other colormap that is installed as a
37       result of a call to XInstallColormap, the X server generates a Col‐
38       ormapNotify event on each window that has that colormap.
39
40       XInstallColormap can generate a BadColor error.
41
42       The XUninstallColormap function removes the specified colormap from the
43       required list for its screen.  As a result, the specified colormap
44       might be uninstalled, and the X server might implicitly install or
45       uninstall additional colormaps.  Which colormaps get installed or unin‐
46       stalled is server dependent except that the required list must remain
47       installed.
48
49       If the specified colormap becomes uninstalled, the X server generates a
50       ColormapNotify event on each window that has that colormap.  In addi‐
51       tion, for every other colormap that is installed or uninstalled as a
52       result of a call to XUninstallColormap, the X server generates a Col‐
53       ormapNotify event on each window that has that colormap.
54
55       XUninstallColormap can generate a BadColor error.
56
57       The XListInstalledColormaps function returns a list of the currently
58       installed colormaps for the screen of the specified window.  The order
59       of the colormaps in the list is not significant and is no explicit
60       indication of the required list.  When the allocated list is no longer
61       needed, free it by using XFree.
62
63       XListInstalledColormaps can generate a BadWindow error.
64

67                 ormap.
