921 | NAME | |
922 | XCreateInsensitivePixmap - create a grayed-out copy of a pixmap | |
923 | ||
924 | SYNOPSIS | |
925 | Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap ) | |
926 | ||
927 | DESCRIPTION | |
928 | This function creates a grayed-out copy of the argument pixmap, suitable | |
929 | for use as a XmLabel's XmNlabelInsensitivePixmap resource. | |
930 | ||
931 | RETURN VALUES | |
932 | The return value is the new Pixmap id or zero on error. Errors include | |
933 | a NULL display argument or an invalid Pixmap argument. | |
934 | ||
935 | ERRORS | |
936 | If one of the XLib functions fail, it will produce a X error. The | |
937 | default X error handler prints a diagnostic and calls exit(). | |
938 | ||
