How to determine if current thread is the UI thread

[huangwf]

Does anybody know how to determie if current thread is the UI thread in Qt3?

Googled for the question, no luck so far ....

Thanks in advance.

Just an info; I'm not sure if this would help - as far as I know the Ui thread is the main thread, the one called from main(). If you can implement comparision of the main thread and the thread you are testing, then it's a way to check.

You could add a static method to your main GUI class and return the current thread from from there. The current thread should be stored as a static member:


QThread MainClass::mGuiThread = QThread::currentThread();
...
QThread MainClass::guiThread()
{
return mGuiThread;
}


Then you could access it in other parts of the program and compare it with QThread::currentThread.
