.SH DESCRIPTION
|
|
The
|
|
.B 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
|
|
.BR XCreateWindow ,
|
|
.BR XCreateSimpleWindow ,
|
|
.BR XChangeWindowAttributes ,
|
|
or
|
|
.BR XSetWindowColormap .
|
|
.LP
|
|
If the specified colormap is not already an installed colormap,
|
|
the X server generates a
|
|
.B 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
|
|
.BR XInstallColormap ,
|
|
the X server generates a
|
|
.B ColormapNotify
|
|
event on each window that has that colormap.
|
|
.LP
|
|
.B XInstallColormap
|
|
can generate a
|
|
.B BadColor
|
|
error.
|
|
.LP
|
|
The
|
|
.B 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.
|
|
.LP
|
|
If the specified colormap becomes uninstalled,
|
|
the X server generates a
|
|
.B 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
|
|
.BR XUninstallColormap ,
|
|
the X server generates a
|
|
.B ColormapNotify
|
|
event on each window that has that colormap.
|
|
.LP
|
|
.B XUninstallColormap
|
|
can generate a
|
|
.B BadColor
|
|
error.
|
|
.LP
|
|
The
|
|
.B 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
|
|
.BR XFree .
|
|
.LP
|
|
.B XListInstalledColormaps
|
|
can generate a
|
|
.B BadWindow
|
|
error.
|
|
