Question

I want to handle events when user pastes some text in TextBox. Which event is fired in this situation? I tried ValueChange and Change handlers, but they didn’t work.

This might help you. Describes a workaround to hook to the onpaste event.
In short:

• subclass TextBox

• sink the onpaste event in the constructor

  sinkEvents(Event.ONPASTE);

• override onBrowserEvent(Event event)

  public void onBrowserEvent(Event event) {
      super.onBrowserEvent(event);
      switch (event.getTypeInt()) {
          case Event.ONPASTE: {
              // do something here
              break;
          }
      }
  }
