How to cancel selection for TreePanel(GXT)

Today, I want to add a function to cancel selection of a tree item in tree panel.

I already implementated this before, but I can’t remember how to do this.

So I search the original code and save here, so next time, I can find it from here.

 

treePanel.getSelectionModel().addListener(Events.BeforeSelect, new Listener<SelectionEvent<ModelData>>() {             @Override             public void handleEvent(SelectionEvent<ModelData> be) {                 // Get the model data                 ModelData model = be.getModel();                // Check the model data and if want to cancel selection, then set canceled value                 if (model.get("disableSelect") != null) {                     be.setCancelled(true);                 }             }         });
