Double click on the Gxt tree to display the popup

How can I catch the double click event in the gxt tree grid? I've already tried this: Click Tree Handlers 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 one click, not double click.
I want the user to double click, a popup will appear.

In this case, the choice has a certain meaning - are you sure you want the doubleclick to trigger the selection, and only then do you want to be notified?

Instead, look grid.addRowDoubleClickHandler

- your handler will be assigned the index of the row that was clicked, and then you can ask the store what item is on that row.

This is the code, I only check the information display:



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