How to add an e4 eclipse part into Show View dialog

Question

I'm developing an eclipse plugin using e4 technologies intended to be run in Eclipse IDE.

How can I add my part (defined as 'PartDescriptor' in fragment.e4xmi file in my plugin) into the "Show View" dialog tree (main menu > Window > Show View > Other ...) ?

Based on examination of org.eclipse.e4.ui.workbench.swt.internal.copy.ViewContentProvider#createChildren source code and based on examination of PartDescriptors of other parts using Live Application Model part I tried to add following tags to my PartDescriptor on Supplementary tab:

• View
• categoryTag:MyGroup

However, it doesn't work for me. I use Eclipse 4.3 and e4 0.14.

It's not possible, says Thomas Schindl at http://www.eclipse.org/forums/index.php/t/499424/

Thans for answers.

I don't think this is the class making up the Show View ... content in the compat layer which is constructed from IViewDescriptors IIRC. Hence if you contribute through a fragment it can't show up there.

It's possible in 4.6.3 (and possibly before that).

You still need the View tag, but categoryTag apparently has been deprecated. Instead, there now is a Category field in MPartDescriptor, which can be set via the Eclipse e4 model editor:
