any idea?

Answer 1

That sounds like a ToggleButton.

Answer 2

This is a pretty basic approach that should give you the toggle that you want. Basically the first click will put a 'clicked style' that you've created that will give the thing the look you want for when it looks pressed. Clicking it a second time will revert back to your normal button style so it will look not pressed again.

final Button button = new Button();
button.setStyleName("NormalButtonStyle");
button.addClickHandler( new ClickHandler() {
  private boolean clickedStyle = false;
  public void onClick( final ClickEvent clickEvent ){
    clickedStyle = !clickedStyle;
    if( clickedStyle ){
      button.setStyleName("ClickedButtonStyle");
    }
    else {
      button.setStyleName("NormalButtonStyle");
    }
  }
});
