How to fire an event when a DialogBox got hided in GWT?

I want to call a method whenever my DialogBox is hidden. It doesn't matter how it is hidden, it could be someone click close button or it can be hidden by itself. When that happen the system will call a method.

Look at this code.

public class WishListDialogBox extends DialogBox {
    @UiField Button closeButton;
    public WishListDialogBox() {
        setHTML("Wish List");
        setWidget(uiBinder.createAndBindUi(this));
        closeButton.addClickHandler(new ClickHandler(){

            @Override
            public void onClick(ClickEvent event) {

                hide();
            }

        });
    }

    @Override
    public void hide() {
        super.hide();
        //call some action here;
    }
}

The above code only work when I click CloseButton, but when the DialogBox was hidden by itself, nothing happened.

There is no onHide event in DialogBox.

In traditional Java, there is addWindowListener to handle his very easily, but that is missing in GWT DialogBox.

So, How to fire an event when a DialogBox is hidden in GWT?

Finally I found a solution

this.addCloseHandler(new CloseHandler(){
    @Override
    public void onClose(CloseEvent event) {
        // TODO Auto-generated method stub
        //do some action here
    }
});
