Adding selection listener to GXT Grid?

Question

I'm trying to add a selection listener to my GXT (Ext GWT) Grid, but I can't seem to get it to fire. I've tried many variations of this with no luck:

myGrid.addListener(Events.Select, new SelectionListener<ComponentEvent>() {

     @Override
     public void componentSelected(ComponentEvent ce) {
         System.out.println("selected");
     }
});

Answer 1

        myGrid.getSelectionModel().addSelectionChangedListener(new SelectionChangedListener<ModelData>() {

        @Override
        public void selectionChanged(SelectionChangedEvent<ModelData> se) {
            ...

        }
    });

Try this code

Answer 2

To upgrade this answer to GXT v3

grid.getSelectionModel().addSelectionChangedHandler(
  new SelectionChangedHandler<ModelData>(){

@Override
public void onSelectionChanged(SelectionChangedEvent<ModelData> event) {
    }
 });

Answer 3

Try:

myGrid.addListener(Events.Select, new Listener<GridEvent<ModelData>>() {
    @Override public void handleEvent(GridEvent<ModelData> be) {
        System.out.println("selected");
    }
});

Replacing ModelData with your model type if necessary.

Answer 4

Seemed to have found a workaround for this:

myGrid.addListener(Events.OnClick, new Listener<ComponentEvent>() {

    @Override
    public void handleEvent(ComponentEvent ce) {
        // Handle the grid event
    }
});

Seems like you just have to be generic about it, then you can check and cast your ComponentEvent to a GridEvent.
