Window.ContextualMenuAction
From Xojo Documentation
Supported for all project types and targets.
Fires when a contextual menuitem HitItem was selected but the Action event and the MenuHandler for the menuitem did not handle the menu selection.
Notes
This event gives you a chance to handle the menu selection by inspecting the menuitem’s Text or Tag properties to see which item was selected. Use this in conjunction with ConstructContextualMenu if you have not specified the Action event or the Menu Handler for the items on the contextual menu.
Example
The following code in a ConstructContextualMenu event builds a simple contextual menu. The parameter Base as MenuItem is passed in as a parameter.
base.Add(New MenuItem("Export"))
Return True // display the contextual menu
The following Select statement in the ContextualMenuAction event handler inspects the selected menu item, which is passed in as the HitItem as MenuItem parameter.
Case "Import"
MessageBox("You chose Import")
Case "Export"
MessageBox("You chose export")
End Select
Return True
