How can I force main message thread to process messages?
I need to wait in my main thread until another thread is finished but keep processing messages. In C# and in Delphi this is simple task.
How to do this in JUCE?
while (thread.waitForThreadToExit(100))
{
//process messages here to avoid freeze
//.NET - Application.DoEvents()
//Delphi - Application.ProcessMessages();
//JUCE - ?????
}
Maybe there's a way without waiting at all? What are you trying to do?
However - http://www.juce.com/doc/classMessageManager might help though. Maybe runDispatchLoopUntil(...)
Yes, you can call runDispatchLoopUntil().
But you should NEVER do this!
Modal loops are a terrible idea from computing's past, and are impossible on modern OSes like Android, where this method won't exist. You may think it sounds like a handy thing to do, but you're almost certainly wrong, and should be looking for other non-blocking ways to do whatever it is that you're trying to achieve.
(Particularly if you're writing a plugin, this is an absolute no-go area, you'll really get into trouble if you use it)
Thank you for advice. I will use CallbackMessage and state machine instead. It is more complicated but I guess in the end it will be better.
A wise choice :)
Although I think that something similar to .Net’s Application.DoEvents(), could be helpful.
I see no reason why someone would need this. I programmed .Net for almost 16 years and never used this.
I would strongly recommend rethinking the design if you end up with something like this.
