Java Game APIs & Engines / Java 2D / Re: Fullscreen/Windowed mode toggling

The way I got it working (clean and fast) was to NOT extend JFrame (like GameFrame) and maintain 2 protected JFrames. The other key was to remove the Insets for the Windowed frame, as below (an extension of JFrame that has this method):

One slight problem with this is that the Insets are not set if you call:

1	JFrame.setDefaultLookAndFeelDecorated(true);

I added a comment about this to this bug report:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5050922

As a side note, when using a KeyListener to switch modes (with ALT-ENTER), it is necessary to put the code in keyReleased instead of keyTyped, as the keyTyped never gets an "ALT-ENTER" key.

            public void keyReleased(KeyEvent event)

                  if(event.isAltDown() && (event.getKeyCode() == VK_ENTER))
                        toggleFullScreen();
            }

It seems there are still 2 bugs present in the disposing of Frames.

I am not currently overriding dispose() at all. I do however have the RuntimeShutdownHook (from http://fivedots.coe.psu.ac.th/~ad/jg/ch03/index.html):

called during init:

1	readyForTermination();

and then...

      protected void readyForTermination()
      {
            Runtime.getRuntime().addShutdownHook(
                  new Thread()
                  {
                        public void run()
                        {
                              fpsTimer.end();
                              setFullScreen(false);
                        }
                  }
            );
      }

this ensures that it is back in the original windowed display mode.

Ok, I got it working. I had been trying to extend JFrame and either modify it or use it with another protected instance of JFrame.

I looked over the Balls.jar example a few times, and couldn't find where setFullScreen was actually doing anything. I realized that SOME of the source files were not included. Using FrontEndPlus, I reversed the other class files (specifically GameFrame), and saw where those changes were.

      public Rectangle getInsetBounds()
      {
            Rectangle bounds = this.getBounds();
            Insets fi = this.getInsets();
            return new Rectangle(
                  bounds.x + fi.left,
                  bounds.y + fi.top,
                  bounds.width - (fi.left + fi.right),
                  bounds.height - (fi.top + fi.bottom)
            );
      }

I would like to say, for any Sun developers who might be watching this, that I think it would be of great benefit (and cleanness of code) to be able to toggle between fullscreen and windowed modes on a single JFrame. The gfxDevice.setFullScreen(boolean) does not allow for this because of the inability to call setUndecorated(boolean) after the Peer has been created (without calling removeNotify/addNotify).

Thanks everyone for the assistance.

Quote I'd post the code (which is quite different from the original balls now..), if only I had the time to create a project on java.net.. I'm not saying that there's no bug there, though.. Please file one.. How do I find that code? Thanks.

Quote I have a test, which is a derivative from the infamous Balls,which automatically changes to and from fullscreen mode for all display modes available, and that thing runs through a whole night of switching.. =) You know, I tried the original Balls.jar, and it worked OK -- but windowed mode was still fullscreen (ie: no decorations)....

I am using 1.5.0b2 right now. I looked through the docs on b3, but it did not appear there were any changes to the FSEM handling. I was however doing the mode change from the mouseListener.... hmm, I will take a look at that.

I've looked through the various JavaGaming posts (including the Balls.jar example) and the Java Forums. I can't seem to find any information on how to correctly toggle between Fullscreen (and undecorated) and Windowed (and decorated) modes. I have tried a few different ways. I have tried using 2 JFrames (one decorated and one not) as well as using the addNotify/removeNotify so that I could call setUndecorated on a single JFrame. In either case, it sometimes goes blank when switching back into Fullscreen, even though the Active Rendering loop continues to process. Does anyone have a simplistic example of how to switch back and forth between the two modes?
