Should I use QCoreApplication::processEvents() or QApplication::processEvents()?
qt, user-interface
Solution
Neither, processEvent() should be calld only when you have actual pending events to process. You may find this useful : How to make Qt work when main thread is busy?
Problem
I have a method which is called from both `QThreads` and the main thread. this method can sometimes take a long time to do its computations in a loop so I put `QCoreApplication::processEvents()` and this prevents the GUI from freezing. At some point I had changed `QCoreApplication::processEvents()` for `QApplication::processEvents()` but that caused the GUI to freeze (im pretty sure thats what was fereezing it because since I put `QCoreApplication::processEvents()` back it hasnt frozen again) Am I right to think that calling `QApplication::processEvents()` from both the main thread and QThreads can freeze the GUI?
