Help me about multithread!

[vql]

Forget about threads in all situations regarding display (rendering as well).

I don't understand clearly. Does it relative with my example:

truckthread.start(); // call truckthread.run(){draw()};
vesselthread.start(); // call vesselthread.run(){draw()};
form.show();

truckthread.start(); // call truckthread.run(){draw()};
vesselthread.start(); // call vesselthread.run(){draw()};
form.show();

To copy to clipboard, switch view to plain text mode 

We can't use threads in this case, because I want truck & vessel drawn on form.

If you can't use threads then why do you use them? I suggested you to stop using threads and you ask how is it related to your problem because you can't use threads?

Thank you very much, wysota.
Finally. I want to ask wysota a question about Coin3D.
I can using Coin + SoQt + MingW (not Visual Studio) on Windows? I tried but failed when compiling Coin with MingW. Thanks.

Anyone can give me a example about thread (use with classes QThread, QMutex, QMutexLocker, or QWailCondition). It's very complex when in my program, must combine above classes. Because, examples in Qt Assistant is very simple.

Thanks.

What exactly is that you want to achieve?
