You must do a event handler (overwrite onBrowserEvent2), CellTable in gwt
2.3.0 doesn't support events. See this example:
@Override
protected void onBrowserEvent2(Event event) {
super.onBrowserEvent2(event);
String eventType = event.getType();
boolean isMouseover = "mouseover".equals(eventType);
boolean isMouseout = "mouseout".equals(eventType);
// Get the event target.
EventTarget eventTarget = event.getEventTarget();
if (!Element.is(eventTarget)) {
return;
}
final Element target = event.getEventTarget().cast();
You can overwrite this method and can open a tooltip.
