"Separate Threads for two independent operators using Java Swing"

I have two separate operators which open a JFrame and do some rendering. The rendering is very CPU consuming and I would like to run both on a separate threads. The two operators and JFrames are completely independent. Is there any way to run the rendering on separate threads? If I recall correctly, there's only 1 swing thread. Just seeing if there's anything that can be done to get around that restriction.

Hi,
you could render into a buffered image and after finishing pass the buffered image to the awt event thread to paint it.

That's a very good idea. I've never tried that before, but thanks for the suggestion. I'll look into it.

Update: Is there an example of drawing to bufferedImage within RapidMiner? I know RapidMiner uses JFreeChart and I can see if-statements for bufferedImage drawing in JFreeChart's XYItemRenderer object.

Hi,
you can just retrieve the graphics object from a buffered image and render into it using the paint Component method as you would do for a JPanel.
By the way: It is generally discouraged to access any awt methods inside operators. This would cause the process to crash in server or command line mode.
I would suggest storing the results in an IOObject, registering a renderer for this result object and then you can take a look at the object instead of outputs created during the process. This way it is much easier to maintain results for documentation, you can even report them.

Sebastian
