I have tried this but didn\'t work

Column imageColumn = new Column(new ImageCell()) {
       @Override
             


        

Answer 1

You can extend ImageCell class and override 2 it's methods - getConsumedEvents and onBrowserEvent. Example:

    private class MyImageCell extends ImageCell{

    @Override
    public Set getConsumedEvents() {
        Set consumedEvents = new HashSet();
        consumedEvents.add("dblclick");
        return consumedEvents;
    }

    @Override
    public void onBrowserEvent(Context context, Element parent,
            String value, NativeEvent event,
            ValueUpdater valueUpdater) {
            switch (DOM.eventGetType((Event)event)) {
            case Event.ONDBLCLICK:
                // TODO
                break;

            default:
                break;
            }
    }

}
