Hi

I try to add a policy to handle keyboard short cuts.
What is the best/preferred way?

I tried to

	@Override
	protected void bindAbstractRootPartAdapters(MapBinder<AdapterKey<?>, Object> adapterMapBinder) {
		super.bindAbstractRootPartAdapters(adapterMapBinder);
		adapterMapBinder
			.addBinding( AdapterKey.get( FXTypeTool.TOOL_POLICY_KEY, "GlobalOnTypePolicy"))
			.to( GlobalOnTypePolicy.class);
	}

This works, as long as nothing is selected. Otherwise not.

thanks
Frank

Up to now, the policies of the focus part (i.e. the one referred to in the FocusModel) receives those key events. The policies of the root part will only receive the events if there is no root part. This means that up to now, you will have to register a respective delegating policies at those parts that may have focus. We are planning to enhance the behavior (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=481678).
