I do it in a small package and it works
. So I was happy but only for a short time. When I try on my own project I still have the same bug : when I clicked on button, nothing happens. After some debug test I find why.
In my game I used TWL for the menu GUI. But in game I used MouseOverArea components and it look like when using StateBasedGame + TWL + MouseOverArea the input are cut by MouseOverArea even if the object is just instantiate and not used in a state that it's not used too.
All the code (one interface and three classes (one StateBasedGame and two BasicGameState)), (need an image for MouseOverArea and a TWL Theme) :
To see the problem just comment/uncomment the MouseOverArea line in MyBasicGameState2 (method init)
Code:
public interface ITWLGameState {
public Widget getRootWidget();
}
Code:
public class MyStateBasedGame extends StateBasedGame {
private static final String THEME_PATH = "resources/themes/guiTheme.xml";
private LWJGLRenderer lwjglRenderer;

public static void main(String[] args) {
try {
AppGameContainer container = new AppGameContainer(new MyStateBasedGame());

container.setTargetFrameRate(100);
container.start();

e.printStackTrace();

//THIS LINE WILL CUT EVENT !!!
MouseOverArea test = new MouseOverArea(container, new Image("resources/images/fow.png"), 200, 200);
}
@Override
public void render(GameContainer container, StateBasedGame sbGame, Graphics g) throws SlickException {
((MyStateBasedGame) sbGame).renderTWL();
}
@Override

((MyStateBasedGame) sbGame).updateTWL();
}
@Override

I need to used both TWL and MouseOverArea in my project so any help is welcome
