Hi all,

I build my own graphical editor and I defined a specific view and a command.
I added the command as a button in the view and I am able to enable this button only if one element in the view is selected.
For doing that I registered the view as a selection provider:


What I'd like to do now is register also the diagram as a selection provider, in such a way that I can enable the button only if one specific editPart (wihch correspond to a specific element in the model) is selected in the diagram.

How can I register the editor as a selection provider? Rolling Eyes

Hi Luca,

the diagram is already registered as selection provider; in every place of your code you can retrieve the active selection with the following code:

IStructuredSelection sel = (IStructuredSelection)PlatformUI.getWorkbench().getActiveWorkbenchWindow().getSelectionService().getSelection();

HTH, bye
