    Hi
    I want to use QProgressDialog in my project. As long as I am not putting QApplication::processEvents() inside the process loop (which significantly slows dows the process) QProgressDialog stops responding.
    Any ideas?

      Hi,

      One solution is to offload the heavy processing to another thread and use signals and slots to update the progress dialog

      Hope it helps

        Thanks. I was thinking maybe QProgressDialog has solved this internally or something :) Maybe some sort of faster QApplication::processEvents() :)

          No, there's no shortcut for the event loop. You may ask to exclude some processing but that's all
