Maik,
The Timer which you are using is a java.util.Timer (not a javax.swing.Timer),
so your rendering function is not being called on the Event Dispatch Thread.
This could be why you are not always getting the GraphicsConfiguration /
GraphicsDevice which you expect (as
Hi Ken,
I'm just at work and see that I call it indirectly through repaint().
To be honest, it confuses me a bit that there are the methods repaint(),
paint(Grphics g) and even update(Graphics g). I'm sure that I read about the
differences and when I have to use one or the other at the time I
If you call repaint() you invoke the AWT thread and paint()
is called by the AWT thread. update() and paint() should
not be called directly by your program they are generally
called from the AWT thread in response to some sort of
system event like Expose or Move etc.
With VolitileImages, you
Hi Ken,
With VolitileImages, you should render directly from
your program by calling your own render method directly.
Don't call repaint().
I do use my own render method, but that method only renders on my background
volatile image. After that is finished I somehow have to get my image onto the
You can certainly use repaint() with VolatileImages as back buffers.
The alternative approach is called active rendering, where you
control when stuff gets rendered.
Take a look at this:

While this is a full
That's the way I do things. I do active rendering using BufferStrategy.
I turn off repaint() setIgnoreRepaint(true) while I'm active rendering and
then when I'm not active rendering and the applet is just sitting there,
I turn on repaint() with setIgnoreRepaint(false) so that if the applet

So, could it be that the recognition of the current screen device can depend on

as I described in my questioning thread, I get the graphics configuration via
viBackbuffer.validate(this.getGraphicsConfiguration) whereas viBackbuffer is
