    Default Dynamic Context in Tree. How to Prevent show after Event ?

    Dynamic Context in Tree. How to Prevent show after Event ?


    Hello,

    i have a dynamic context menu on each node. Sometime its to possible to get a context menu without any items. Sadly the context menu show a clear rect on the screen.


    How its possible to prevent this ?

    Here my Code:
    Code:
     Menu contextMenu = new Menu();
           tree.addListener(Events.ContextMenu, new Listener<ComponentEvent>() {
                public void handleEvent(ComponentEvent be) {
                    Object selectedObject = tree.getSelectionModel().getSelectedItem();
    
                    Menu contextMenu = cfactory.createContextMenuselectedObject);
                    addNewEntriesMenu(contextMenu,selectedObject);
    
                    if (contextMenu.getItemCount()==0) {
                        //tree.setContextMenu(null); // cant set to null cause no more events fired.
                        // add usefull thing here to prevent show contextmenu 
                    }
                    tree.setContextMenu(contextMenu);
                }
            });
            tree.setContextMenu(contextMenu);

    You can simple cancel the Events.ContenxtMenu event if you dont want to open the menu.

        be.stopEvent();
        be.getEvent().stopPropagation();
        return;
    }

    because you have not cancelled it. None of the methods you called contain the word cancelled

    what about
    Code:
    be.setCancelled(true);
