Disable context menu

[batkins]

I'm trying to disable the context menu of a LayoutContainer when it's mask. I see a protected method, "disableContextMenu(boolean)", but it doesn't appear to work. Although it does call "event.preventDefault()" when set, it still calls Component.onRightClick(), which posts the dialog. I'm not sure of this is a bug, and the call to onRightClick should be within the if statement, or whether there is another way to disable a Component's context menu.

Thanks!

You want to disable the native browser contextmenu or a contextmenu you set with component.setContextMenu?

Both, actually. I have set a context menu of my own, and when the container it's attached to is masked, I don't want the right click event on that container to do anything. I don't want to post my own context menu, but I also don't want it to default back to posting the browser's context menu.

Add a listener to the Events.ContextMenu event and cancel that. Than your own contextmenu wont be shown. disableContextMenu only disabled the native browser contextmenu.

Perfect, thanks!

I also want to disable a my own context menu on a treepanel.
I've tried a few variations eg. Listener<BaseEvent>, Listener<Component> and cancelBubble, stopEvent, setCancelled, etc.
So far no luck.
Please help.

Here is one example:

Listener<ComponentEvent> cancelContextMenuListener = new Listener<ComponentEvent>() {

                    @Override
                    public void handleEvent(ComponentEvent be) {
                        be.cancelBubble();
                    }
                };
                tree.addListener(Events.OnContextMenu, cancelContextMenuListener);

cancleBubble is not cancelling an event, it just stops event bubbling. stopEvent will prevent the default action and also stop bubbling. This way the browser contextmenu should not appear.

I have changed the code to use stopEvent(), but it's still not working.
It looks like it is only disabling the native context menu. It is not disabling my custom context menu. How can I achieve that?

[sven]

Disabling the custom context menu is not linked to any browser event. You need to "cancel" the ContextMenu event.

Ok, but how?
