Bug 182505 [FieldAssist] API - ContentProposalAdapter needs hasProposalPopupFocus() method
Please implement a method ContentProposalAdapter.hasProposalPopupFocus() like org.eclipse.jface.text.contentassist.ContentAssistant.hasProposalPopupFocus(). The method should return a boolean whether the content assistant proposal popup has the focus or not.

public void handleEvent(Event e) {
				if (!isValid()) {
					return;

				char key = e.character;
				
				
				if (e.type == SWT.Traverse) {
					
					
					
					
					
					if (key != 0) {
						e.doit = false;
						return;
					}
					
					
					
					
					e.detail = SWT.TRAVERSE_NONE;
					e.doit = true;
