| 958 | NAME |
| 959 | XCreateInsensitivePixmap - create a grayed-out copy of a pixmap |
| 960 | |
| 961 | SYNOPSIS |
| 962 | Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap ) |
| 963 | |
| 964 | DESCRIPTION |
| 965 | This function creates a grayed-out copy of the argument pixmap, suitable |
| 966 | for use as a XmLabel's XmNlabelInsensitivePixmap resource. |
| 967 | |
| 968 | RETURN VALUES |
| 969 | The return value is the new Pixmap id or zero on error. Errors include |
| 970 | a NULL display argument or an invalid Pixmap argument. |
| 971 | |
| 972 | ERRORS |
| 973 | If one of the XLib functions fail, it will produce a X error. The |
| 974 | default X error handler prints a diagnostic and calls exit(). |
| 975 | |
