Creating Graphical User Interfaces

List Boxes

Triggering Callback Execution

MATLAB evaluates the list box's callback after the mouse button is released or after certain key press events.

• The arrow keys change the Value property and trigger callback execution.
• Enter and Space do not change the Value property but trigger callback execution.

If the user double-clicks, the callback executes after each click. MATLAB sets Selection Type to normal on the first click and to open on the second click. The callback can query the Selection Type property to determine if it was a single- or double-click.
