Hi guys,

I have implemented a GEF based editor. My problem is with Undo and Redo actions keybindings.

The code in my editor

protected void createActions() {
	ActionRegistry registry = getActionRegistry();
	IAction action;
	
	action = new UndoAction(this);
	registry.registerAction(action);
	getStackActions().add(action.getId());
	
	action = new RedoAction(this);
	registry.registerAction(action);
	getStackActions().add(action.getId());
	
	...
}

and in my ActionBarContributor

@Override
protected void buildActions() {
	addRetargetAction(new UndoRetargetAction();
	addRetargetAction(new RedoRetargetAction());	
}

@Override
public void contributeToMenu(IMenuManager menubar) {
	super.contributeToMenu(menubar);
	IMenuManager editMenu = menubar.findMenuUsingPath("edit");
	if (editMenu != null) {
		editMenu.insertBefore(IWorkbenchActionConstants.MB_ADDITIONS, getAction(ActionFactory.UNDO.getId()));
		editMenu.insertBefore(IWorkbenchActionConstants.MB_ADDITIONS, getAction(ActionFactory.REDO.getId()));
	}	
}

Undo/Redo works fine except there is no key bindings for them. My code is same as in Logic example and when I run it, keybindigs work there.
Any ideas?

When I put this code to my ActionBarAdvisor

@Override
protected void makeActions(final IWorkbenchWindow window) {
	register(ActionFactory.UNDO.create(window));
	register(ActionFactory.REDO.create(window));
}

and edit editor's ActionBarContributor

@Override
protected void buildActions() {
	addRetargetAction(new UndoRetargetAction() {
			
		@Override
		public String getActionDefinitionId() {
			return ActionFactory.UNDO.getCommandId();
		}
	});
	addRetargetAction(new RedoRetargetAction() {
			
		@Override
		public String getActionDefinitionId() {
			return ActionFactory.REDO.getCommandId();
		}
	});
}

it works fine, but I don't think that it's the right solution.
It should work just with addRetargetAction(new UndoRetargetAction());

Does your editor extend

GraphicalEditor

? if so, why not call

super.createActions()

to enable the undo, instead of repeating the same code that already exists in

GraphicalEditor

? I say this because this is what I do in my editor and things are working just fine. Its worth a try Smile

Hi Arieh,

yes, my editor extends GraphicalEditor and I don't override makeActions().
I just copied content of the GraphicalEditor's makeActions() method here to mention that Undo/Redo are properly registered.

Well as I said, Undo/Redo works, but theirs keybindings doesn't Sad
