How to add a custom JFace Viewer?

[DirkSegelhorst]

How can I add my own custom JFace Viewer to the palette and use it in the designer? The designer shows it, but it cannot be dropped on a composite.
The viewer used in my example is the CTreeComboViewer from Tom Schindls CTreeCombo implementation:

Simple custom widgets can be added using the Palette Manager.

Custom viewers typically don't conform to any specific API, so you need to use the WindowBuilder Customization API to add it to the palette.

See the New Component Tutorial and Customization API docs.

See the following *.wbp-component.xml file for this viewer. Put it in the same package as the viewer class, or into a parrallel wbp-meta folder with the same package structure.

You will also need the following palette file to contribute this viewer to the existing JFace category. It should go into the wbp-meta folder.
