I apologize, I'm probably blind and forgetting something extremely easy.

I've included TWL with my Slick project, but I can't get my button to show up, no matter what I try.

Taken from your wiki:

Code:

@Override
   protected void createRootPane() {
      super.createRootPane();

      button = new Button("New Game");
      button.addCallback(new Runnable() {
         @Override
         public void run() {
            System.out.println("it works");
         }
      });

      rootPane.add(button);
   }

   @Override
   public void layoutRootPane() {
      button.adjustSize();
      button.setPosition(100, 100);
   }

I get no errors (except state0/state1 themes not found) but nothing is visible.
My theme for testing purposes is from this thread: viewtopic.php?f=18&t=4859

Code:

@Override
   protected URL getThemeURL() {
      return Game.class.getResource("/me/game/theme/chutzpah.xml");
   }

Any help appreciated.

Do you get any messages on System.err ?

Could not find theme: state0
Could not find theme: state1

This is all I get.

In the meanwhile I've included the newer version of the TWLSlick.zip in my projects. I'm now doing the following:

Code:

@Override
   public void layoutRootPane() {
      button.adjustSize();
      button.setPosition(100, 100);
   }

   @Override
   public void init(final GameContainer container, final StateBasedGame game) throws SlickException {
      super.init(container, game);

      button = new Button("New Game");
      getRootPane().add(button);

        ....
}

But it's still as before - nothing is shown.

there is some theme missing for the button. Has the xmxl file a button theme?

Yes. I've tried using setTheme() on the rootPane and/or button to no avail.

You should upgrade the theme with the fallback theme.
Add this to "-defaults":
<theme name="" ref="*"/>

And add this as top level theme after the "-defaults":
<theme name="*" ref="-defaults"/>

I've added the fallback to the theme and uploaded a new version.

The slick examples set the root pane's theme to "state0", "state1", etc. So it's looking for the theme called "state0.button" which doesn't exist. The fallback should now fix that, but you'll still get a warning message.

Ideally you should just clear the root pane themes unless you need them. In each state's init(), use the following:

Code:

getRootPane().setTheme("");

Thank you guys, I've upgraded the XML file.

Button is still not visible, though.

Code:

@Override
   public void layoutRootPane() {
      button.adjustSize();
      button.setPosition(100, 100);
   }

   @Override
   public void init(final GameContainer container, final StateBasedGame game) throws SlickException {
      super.init(container, game);
      getRootPane().setTheme("");

      button = new Button("New Game");
      button.setTheme("button");
      getRootPane().add(button);
        ...
}

System.err: Selected fallback theme for missing theme "state0"

I really don't know what's wrong here. Couldn't be an OpenGL problem or something like that, could it?

It seems more likely a problem elsewhere in your code. Try running this test, main class is TWLGame:

Your test code works perfectly with the same libs/jars I'm using in my main project, so it's indeed an error in my code.

I needed to change serveral methods from protected to public since I put the TWLSlick files in several packages. But I guess this won't do anything.
I'm also using MarteEngine, so my BasicTWLGameState is extending World, which is extending BasicGameState. But I already checked Override problems

I really don't get it. Makes absolutely no sense.
The above test works perfect, I copy the same stuff into my game structure and I see NOTHING. I even disabled all the states but my main menu state. Nothing...

I've added MarteEngine to the Test and it still works, so no problems there. I'm confused

Still trying to fix this error.

When I do it the following way:

Code:

public void init(GameContainer container, StateBasedGame game) throws SlickException {
      super.init(container, game);

      getRootPane().setTheme("");

      btn = new Button("Hello, world!");
      getRootPane().add(btn);
   }

   @Override
   public void layoutRootPane() {
      super.layoutRootPane();

      btn.adjustSize();
   }

(Leaving out the position and adjustSize)

I get this result:

Does this mean something to anyone? Is this intended to look like this?

You could verify the size of the root pane?

getRootPane().getWidth/Height returns 0 for either. So I guess that's the problem?

LWJGLRenderer().getWidth/Height returns 32/32 after initialization. Also strange, isn't it?
