Close QMessageBox which has WindowStaysOnTopHint flag set

jastmc

Hi,

I am using a touchscreen on a Beaglebone and I find that I have to set the WindowStaysOnTopHint flag, otherwise push buttons on the screen seem to require two taps to activate them.

So, I have a messagebox as shown below and the problem is that it doesn't close when the OK or Cancel buttons are pressed when the WindowStaysOnTopHint flag is set. I've tried close(), hide() and done() but they are not closing the messagebox for me.

How do I get around this? Please point me to solutions.

Regards,
James

        QMessageBox msgBox(QMessageBox::Warning,
                           tr("My Application"),
                           tr("No Sync Detected!\n" "Proceed?"),
                           0, this,
                           Qt::FramelessWindowHint
                           );

        msgBox.setWindowFlags(Qt::WindowStaysOnTopHint);
        msgBox.setStandardButtons(QMessageBox::Ok | QMessageBox::Cancel);
        msgBox.setDefaultButton(QMessageBox::Ok);
        int ret = msgBox.exec();    

        msgBox.close();
        msgBox.hide();
        msgBox.done(0);


        switch (ret)
        {
            case QMessageBox::Ok:
                qDebug() << "OK Pressed!";
                StatusFlags.SYNC_OVERRIDE = 1;
                ProceedToPulseScreen();
                break;
            case QMessageBox::Cancel:
            default:
                qDebug() << "Another Button Pressed!";
                break;
        }

Hi
I cannot reproduce this on either windows 10 or linux (mint)
so maybe its related to the windows manager you are using ?
