19.4.2 Specifying menu callbacks

The callbacks that are necessary for the menu system are much simpler than for the layouts; the example interface only contains two menu commands, and they only require one callback each.

  1. Click the Menus tab to switch to the menus view.
  2. Choose the "Graph" menu item, display its Attributes dialog and change the CALLBACK attribute to 'display-graph-selection . Click OK .
  3. Choose the "List Panel" menu item, display its Attributes dialog and change the CALLBACK attribute to 'display-list-selection . Click OK .
