Gxt tree grid double click to show pop up

Question

How do I catch double click event in gxt tree grid? I already try this from : Click Handlers for Trees in GXT 3?

tree.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
tree.getSelectionModel().addSelectionHandler(new SelectionHandler<MenuView.MenuDto>() {

    public void onSelection(SelectionEvent<MenuDto> event) {
        MenuDto mnu = event.getSelectedItem();
        Info.display("Tree Handler", mnu.getDescripcion());
    }
});

But it only works for single click, not double click.
I want if user press double click, pop up will show.

gwt and gxt is used java, i already change tag, thank. – Nov 05 '14 at 04:59 — , Nov 05 '14 at 04:59

Selection has specific meaning in this case - are you sure you want doubleclick to cause selection to happen, and only then you want to be notified?

Instead, look at grid.addRowDoubleClickHandler - your handler will be given the row index that was clicked, and you can then ask the store what item is in that row.

Relevant GXT Javadoc:

This is the code, i only test to see info display :

tree.addRowDoubleClickHandler(new RowDoubleClickHandler() {
    @Override
    public void onRowDoubleClick(RowDoubleClickEvent event) {
        Info.display("hello", "double click");
    }
});
