test13.c

安装DDD之前

/* Purpose: test grab handling with multiple toplevel shells.
            Do not use this for geometry testing.  (unless you really want to 8))

            To duplicate problem:
            1. Start application
            2. Click New Form button
            3. Click the arrow button on every combobox.
            4. Close the window with the comboboxes and I do not mean minimize.
            5. Click the New Form button
            6. Click the arrow button on every combobox.  You should now
               see Grab errors.
