I have a PlayerListener that's supposed to call invalidate on a Field while the Player is playing. I don't know why but the field is not being repainted. Here's the code:

public class PlayerHandler implements PlayerListener {

	public PlayerHandler() {
	}

	public void playerUpdate(Player player, String event, Object data) {
		if (event == (PlayerListener.STARTED)) {
			new Thread(new SelectFieldUpdate()).start();
		} else if (event == (PlayerListener.STOPPED)) {
			field.invalidate();
		}
	}
	
	private class SelectFieldUpdate implements Runnable {
		public void run() {
			while(player.getState() == Player.STARTED) {
				field.invalidate();
				try {
					Thread.sleep(1000);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			}
		}
	}

}

 of course, i add this listener to my player. any help will be appreciated.

Thanks!

Did you use JDE debugger and the Breakpoints to check the invalidate is executing?

[babygodzilla]

yeah I tried the debugger. invalidate is definitely being called. i'm not sure if anything is actually happening though. it looks like paint may have ran once and that's it, but invalidate keeps being called, presumably because of the while loop, so that much is correct. I don't really have a good grasp of the UI Stack and such. is there something that could be interfering with the painting? needless to say the Player is running at the moment, although that should be running in a different thread as well. i tried encapsulating the insides of paint() in a Runnable, but instead nothing got drawn. no clue what's going on....

edit: instead of invalidate() i tried to call setText() on a different LabelField within that Runnable and I got a IllegalStateException what the heck does this mean?

Try this

UiApplication.getUiApplication().invokeLater(new Runnable()
{
      public void run()
      {
         //set Text
       }
});
