I have a TableView and would like to show a Context Menu when right-clicking.

I do as follows:

final ContextMenu cm = new ContextMenu();
cm.getItems().add(new MenuItem("bu"));
table.setContextMenu(cm);


For a "vanilla" FXApplication it works as expected. When I try the same in an e4 context, the Context Menu does not show up.

The View/Part class looks like this:

public class ViewTable {

	@Inject
	protected Composite parent;
	private FXCanvas fxCanvas;

	public ViewOrphanPeaksTable() {
	};

	@PostConstruct
	public void createControl() {
		init(parent);
	}

	protected void init(final Composite parent) {
		// this will initialize the FX Toolkit
		fxCanvas = new FXCanvas(parent, SWT.NONE);
		Platform.setImplicitExit(false);
		Platform.runLater(() -> createScene(parent));
	}
	@Focus
	public void setFocus() {
		fxCanvas.setFocus();
	}
}

Anyone using FX context menus together with an e4 view part?

I found a workaround.

fxCanvas.addMenuDetectListener(l -> {
    System.err.println("Hey there!");
});


Is a MenuDetectListener the intended way to show a context menu?

I think I've already seen this problem - just to make sure bringing up the context-menu (without your hack) using the the keyboard shortcut does work right?

Never tried that. How do I assign a key combination to a context menu?

cm.setAccelerator(KeyCombination.keyCombination("Ctrl+O"));

does not work.
