SurfaceImage fails to appear

[benlawry]

I've run into a pretty strange issue. To give some background, my software has a number of different JPanels all embedded within a single JFrame. One of the panels has WorldWind in it, the others are all native Swing components. I've made each panel "dockable" - that is, either all of the panels can be integrated into a single frame, or they can each be "undocked" into their own frames. This can be done at the user's request at any time.

So here's the issue - initially, the application starts up with all of the different panels "docked". After generating a BufferedImage, I add it to a SurfaceImage, then add that SurfaceImage to the globe. Nothing shows up. However, if I undock all of the panels into their own frames, then recreate the SurfaceImage and add it to the globe, it works fine. If I redock all of the panels and generate new SurfaceImages while all of the panels are docked, the SurfaceImages work just fine. Any ideas on what might be causing this?

BTW - I'm using a Quadro FX 3700 with 512MB of video memory on an Intel Core2 Quad with 8GB of RAM. I've seen issues on machines with integrated graphics cards, but this machine isn't one of them and has never had a problem running WorldWind before.

is your initially docked panel getting focus correctly? perhaps the scene isnt redrawing.

Have you tried keeping the popup open to see if that resolves the problem? (I'm wondering if somehow the code that hides the popup is also hiding the SurfaceImage.) From what you've described, I suspect the problem is in the code that creates and adds the SurfaceImage to the globe. Something in this sequence must be failing the first time around, but working after that. You might also try adding some code that just creates a simple SurfaceImage without any user interaction, to verify that SurfaceImages themselves are working.

I finally figured this out - here's what's happening (turns out it's Java Swing and not WorldWind).

One of the "panels" is essentially a JTable that contains a list of Polylines, representing a Line of Bearing from some point to some "event". Each time the user clicks on a Polyline in the table, all renderables are removed from the globe and only the selected Polyline is displayed on the globe. This table does have a KeyListener associated with it so that the user can use the arrow keys to navigate through the table... this might seem off subject, but bear with me...

In my program, the user has to select two Polylines from the table before generating a SurfaceImage. I use JOptionPane to get some input from the user prior to generating the SurfaceImage. When the user is done, he can either click "OK" or hit the "Enter" key. When clicking "OK", everything works as it should. However, when the user hits the "Enter" key, for some reason unknown to me, JOptionPane isn't consuming the KeyEvent, so that KeyEvent gets passed on to the JTable. Prior to the KeyEvent being consumed by the table, the new SurfaceImage is generated and rendered briefly. Then, when the table gets the key event, it removes all renderables (as it should), then displays only the polylines that were selected in the table.

So... bottom line is, Java Swing is behaving oddly in that JOptionPane is not consuming the KeyEvent when the user hits "Enter" to create the SurfaceImage. The KeyEvent is still being passed on to the JTable, which is behaving exactly as I intended... haha. So the quick fix is just to have my table ignore all KeyEvents that happen as a result of the "Enter" key being pressed.

Anyway, thanks for the suggestions - I know that ultimately, this is a problem with Swing and not with WorldWind, but your comments got me on the right track. I sure appreciate your time!
