Make pattern registry UI display patterns according to namespace hierarchy

[istvanrath]

Instead of the flat list, I would like the pattern registry UI to display patterns like the package explorer (i.e. checkbox tree, but the packages should be "compressed").

Also, if one registers patterns, the pattern registry drawer should automatically open from the left, to show the newly registered patterns.

Also, the Details/Filters drawer should be visible by default.

I'm working on this issue, but it is a bit complicated.

An additional request: it would be useful to add the ability to unregister multiple patterns in one go (e.g. by allowing multi-select).

I use CheckboxTreeViewer for the issue, and I think it does not support multiple selection. Maybe, @ujhelyiz knows some other SWT widget that can deal with multiple selection. As an alternative solution, I have implemented the pattern unregistration to handle multiple unregistrarions, ie. when selecting an element from some upper hierarchy level.

Note that the implementation is not fully functioning atm.

Most (if not all) JFace viewers support multiple selection by adding the SWT.MULTIPLE or some similar style bit to the constructor. And because a Table is the underlying widget for the CheckboxTreeViewer, this should work.

Can you implement the "Package presentation / Flat" behaviour from the Package Exporer?

I need some ideas here, as I think you want to see these buttons on the flyout of Pattern registry itself, not on the "triangle" of the Query Explorer's view. I searched around but could not really find anything how to solve this drop down on a composite.

I think this functionality is complete and close the issue. If further problems would appear please open an individual issue.
