Hi all friends,

I'm working with Sirius to develop my own diagram.
I want to get element on diagram, which User is hovering mouse over.
Do you have any idea to get element from mouseover event?

I would try this: Create a dummy tool with a dummy predicate expression
that calls a java service. In your service method, set a breakpoint.
Start a debug session, disable the breakpoint. Hover over some element
and then activate the breakpoint which should hit as soon as you move
the mouse. Then look at the stacktrace and you should get some clues.

Well rofl, that's impossible to do.. But anyway, the breakpoint should
hit as soon as the mouse enters the diagram..

I follow your hint, however I cannot hovering mouse during enable breakpoint.

As my investigation, hovering mouse to element is processed by SiriusPopupBarEditPolicy (PopupBarEditPolicy). And I'm stuck in modify popupbar editpolicy, replace the default SiriusPopupBarEditPolicy by my own editpolicy.

I think there is extension to add popupbar editpolicy.

I seem to remember that the predicate expression breakpoint will hit as
soon as you enter the diagram with your dummy tool?

I have no clue about that.
