      Currently my MainWIndow is set as a sharedpointer spMainWindow
      setup as a
      @QSharedPointer<MainWindow> spMainWindow= QSharedPointer<MainWindow>(new MainWindow(nullptr, &mSettings));@ //create our window to start processing

      I have setup a timer that will reset the tab (hopefully) after x minutes of non use -- the slot is working, but on entrance to the tab function I get a seg-fault...

      My basic function is this:
      @
      void moveUiToDefaultTab(void)
      {
      qDebug()<<"Application UI moved to Default tab due to inactivity...";
      m_idleTimer.stop();
      m_idleTimer.start();
      if (spMainWindow->mPages->currentIndex() == 0) return;
      spMainWindow->mPages->setCurrentIndex(0);
      }
      }
      @

      I believe I am crossing into a separate thread - (maybe not)

      What is needed to correct my seg-fault?

        Hi and welcome to devnet,

        Maybe a silly question but, did you initialize mPages properly ?
