SettingTab on MainWIndow from a timer



  • 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 ?
