Snippet99 requires modification as Command+Q is not implemented.
Currently, the snippet demonstrates a message box pop-up when attempting
to close the dialog window, but pressing Command+Q closes the window
without triggering this behavior. The snippet has been updated to
implement Command+Q functionality and to add an SWT dispose listener to
the display object.
