15.4 Specifying callbacks in the interface definition
15.4.2 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. Choose View > Menus 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.
