Description Alexander Nyßen

Up to now, creation of new items is only possible via the context menu. We should enhance the example to provide a palette, which allows some prototype-based creation through drag-and-drop. In contrast to GEF 3.x the palette should render a minimized version of the actual element visualizations rather than providing icons.

The intended way to realize this would be to have a second FXViewer for the palette, using an JavaFX splitter to arrange both. This approach is currently blocked by bug #480489, as it prevents mouse events from reaching both viewers in such a scenario.

I added support for "role-base" adapter injection. This way, we can now defined bindings for several FXViewer instances by using the respective viewer role in the adapter map bindings. Up to now, the mechanism requires that type keys are specified for all adapters that are injected role-based, as we cannot infer their types from the bindings yet. I will try to enhance this, so we have the same 'comfort' for role-based bindings.

I added a palette viewer to the MVC Logo example. Per default, the palette is hidden. A palette indicator is anchored to the left of the content viewer. When the indicator is hovered, the palette is opened and elements can be dragged into the content viewer.

The changes are published on the master branch. Therfore, I resolve this ticket as fixed for 4.0.0 RC1.
