 * a footer that contains any action widgets.

The basic MessageDialog class specifies two actions: ‘accept’, the primary action (e.g., ‘ok’) and ‘reject,’ the safe action (e.g., ‘cancel’). Both will close the window, passing along the selected action.



When the window is opened with the window manager’s openWindow, a new action set can also be passed to the window. The following example illustrates a message dialog with a single action labeled ‘Dismiss.’ The action itself is ‘accept’, defined by the class.

For long messages, use the verbose option to left-align and adjust the message styling:
