Notification for part maximization/minimization [message #488836]

Dear all,

I've been trying to be notified by the platform when a view is minimized
or maximized. I have failed to do this and searching through the group
suggests that it is impossible.

Is this really the case, i.e. there is no way to get this information?
So far I've tried all kinds of listeners and also replacing the global
MAXIMIZE action which did not work.

If there is any way to do this, please let me know. :)

There's no way to do this ATM. You might be able to guess from part visible/hidden events, but I don't think so.

On an activate or a hidden event, you can ask the IWorkbenchPage for the state of the active part. If it is maximized then its state should return IWorkbenchPage.STATE_MAXIMIZED

Alternatively you an open an enhancement request to have the perspective events include a MAXIMIZE event. https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=UI

Okay. Yes, I also think this is in general not the way to go.

I was also thinking about asking for a RESIZE event to be fired in the
case of maximizing or restoring a part, because after all that is what
(additionally) happens to the part contents. What do you think?
