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.
