simultaneous graphics and music THREADS with SwingWorker but not working :(
Hello
[I sent this originally to java essentials group but got no answer...]
please tell what is wrong with my definitions ofSwingWorker
probably just a small basic problem... i am running out of time, so your help is very valuable.
My Idea is to havegraphics activities in the main thread, so calledEvent dispatching thread
To avoid slow down i try toplay simultaneously music in another thread, so calledworker thread
I am a newbie, soplease tell in detail what are the lines that i should change in my code.
Thank you very much for your kind help!!!!
(p.s. later i will try to play midi music, here in my test application i just play 'beep' for simplicity.)
