Mouse listener on tab item of a workbench part [message #660247]

Hi All.
How do I add a mouse listener to the tab item of a workbench part? I need to be notified about any mouse click on the tab not just when the workbench part is activated.

As far as I can see the tab item is created deep inside the StackPrensentation so how do I get hold of it so that I can attach a mouse listener to it?

Thanks in advance,
Anders

I don't think its accessible via API. What is your usecase?

Hi Prakash.
The use case is that when I click on the tab of the editor then I need to put focus to a specific component.

Best regards,
Anders

Can't you override editorPart.setFocus() to do that?

Unfortunately no, because WorkbenchPart#setFocus is only called when the editor becomes the active editor. Not when it already is the active editor.

As Prakash mentioned, there's just now way to interact with the tab in
the editor or view stack, unless you create them yourself.

When your part is activated, setFocus() will be called. Except for
when the editor is already the active part, you'll get the call.

Re-clicking on the active part to change focus is not a common pattern
within an editor/view.

Hi Paul.
But what about the scenario where focus goes to another part of the workbench and then the tab of the editor is clicked? For instance, in the Eclipse IDE I click in the "Package Explorer" view. The focus frame is moved to this view. Then I click on the tab of the active editor and the focus frame is now moved to the editor. How is this implemented.

Thanks in advance,
Anders
