Hi out there,

I'm migrating an eclipse 3.x app to Mars (3.5.1) using comp layer. Almost everything is fine exept the toolbar icons in the toolbar. I'm using different toolbar icon sets in different perspectives (as usual for the perspective paradigm). When switching the perspective, icons are disappearing and occuring, so this is ok as intended. But the auto layout is not working. Gaps are occuring at the place where icons disappear. See screenshot. It seems that "packing" the toolbar ist not triggererd. Or perhaps I am missing a required plugin. I'm NOT using the E4Application class to start the app, it is an own implementation of IApplication. Also I'm NOT using css styling. Its just the plain old 3.x app on comp layer.

Here are my loaded Eclipse RCP plugins in the app:

It would be really helpful if you could come up with a small example to demonstrate the problem.

Eclipse Platform committer. Ask me about Eclipse support, training, and consulting.

Ok,
I added a demo project. I used eclipse mars rcp 4.5.1 as IDE and target platform. I made toolbar contributions via actionSet and commands. It seems that commands dont produce gaps in the toolbar. The demo project can also be obtained at github: https://github.com/hawkinshawk/eclipse-e4-icon-gap-test

Screenshot is attached. The gap is marked with a red square.

I decided to migrate from actionsets to commands. Without deprecated actionsets the gaps in the toolbar disappeared. So as a part on migrating to E4 you should replace actionsets with commands. Sebastian
