3.2.9 Colormap Attribute

The colormap attribute specifies which colormap best reflects the true colors of the InputOutput window. The colormap must have the same visual type as the window, or a BadMatch error results. X servers capable of supporting multiple hardware colormaps can use this information, and window managers can use it for calls to XInstallColormap(). You can set the colormap attribute to a colormap or to CopyFromParent (default).

If you set the colormap to CopyFromParent, the parent window's colormap is copied and used by its child. However, the child window must have the same visual type as the parent, or a BadMatch error results. The parent window must not have a colormap of None, or a BadMatch error results. The colormap is copied by sharing the colormap object between the child and parent, not by making a complete copy of the colormap contents. Subsequent changes to the parent window's colormap attribute do not affect the child window.
