问题
I want to identify from where the ContextItemDoubleClick event is triggering in enterprise architect . (For eg) if i double click on a project browser in EA i need to identify it was triggered from project browser , because now ContextItemDoubleClick is triggering whenever user doubleclicks inside EA . Is it possible to identify that it triggers from project browser or open diagram or diagram object ?
回答1:
No, you can't. At least not from EA:
This event occurs when a user has double-clicked (or pressed the Enter key) on the item in context, either in a diagram, in the Project Browser or in a custom compartment. Add-Ins to handle events can subscribe to this broadcast function.
You won't likely analyze the current screen contents and make a guess where the mouse cursor is positioned, will you?
Ask yourself (or tell us) why you want to do that to find some alternative solution for your underlying issue.
