How to create multiple windows in separated threads using Qt?

[Squall]

Hello
If I have multiple windows and single thread, if there be a problem or delay with one of windows, the other windows will not respond until the problem with that window be solved. I want to avoid this problem and use a thread for each window.
Thanks

You can't use threads with widgets. Offload time consuming jobs to worker threads but do widget processing in the main thread only.
