-SYNOPSIS
+ NAME
+ XCreateInsensitivePixmap - create a grayed-out copy of a pixmap
+
+ SYNOPSIS
Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
-
-DESCRIPTION
- This function creates a grayed-out copy of the argument pixmap, suitable
- for use as a XmLabel's XmNlabelInsensitivePixmap resource.
-
-RETURN VALUES
- The return value is the new Pixmap id or zero on error. Errors include
- a NULL display argument or an invalid Pixmap argument.
-
-ERRORS
- If one of the XLib functions fail, it will produce a X error. The
- default X error handler prints a diagnostic and calls exit().
-
-SEE ALSO
- XCopyArea(3), XCreateBitmapFromData(3), XCreateGC(3), XCreatePixmap(3),
- XFillRectangle(3), exit(2)
