e4 hide PartStack Restore button [message #900872]

In my e4 RCP app I would like to have a minimized PartStack that does not show the restore button on the TrimBar or any of the Parts within the PartStack. I want the "floating" effect with the PartStack permanently anchored to the TrimBar.

I've programmatically removed the "Restore" ToolItem on the TrimBar by disposing it (please advise if there is a better way), but I'm stuck on trying to remove the refresh button from the part's trim.
Thanks.

Can you show a screenshot, I think I can't follow. You should never
dispose something your own, everything has to come through the model or
you need to contribute a customized renderer.

Hi Tom-
I want to hide the two restore buttons (circled in red in the screen shot) for my own Part.

That type of behaviour is handled by the MinMaxAddon, contained in org.elipse.e4.ui.workbench.additions.swt. You can either roll your own or hack up the existing one to add the flexibility as to be configurable to handle your situation as well. You should create a bug to track any discussion at:

Thanks, Brian. I created https://bugs.eclipse.org/bugs/show_bug.cgi?id=386929

So I'm trying to roll my own, but it seems like org.eclipse.e4.ui.workbench.addons.minmax.MinMaxAddon is still active as long as I have org.eclipse.e4.ui.workbench.addons.swt included in my runtime configuration. I have a dependence on org.eclipse.e4.ui.workbench.addons.swt for the DnDAddon.

Another issue with rolling my own MinMaxAddon is the use of e4 internal API (ShellActivationListener), which feels dirty.

If I roll my own MinMaxAddon, do I also have to roll my own DnDAddon?
Thanks

It's not ideal. I'd suggest you import the source, modify MinMaxAddon to allow specifying a policy (perhaps a subclass installed in the application's context?) and submit a patch.
