    I see. I should open the dialog only when I have a valid file selected. Sure, that would be possible. It would be a bit more code since I have to do the select and check twice, once in the mainWindow and once in the dialog. Thanks for the idea, did not think about that. =)

    @Panoss well if you want the widget to become bigger or smaller depending on the size of the window then you must use layouts. Else they wont. So it depends on what your goal is. Yes using layouts takes some practice but the rewards are great.

    There will be one QApplication for each Application. Even for COM components it will be same as Qt provides the container in the form QaxObject and QaxWidget. Every object looking for QApplcation access the same the qApp variable exposed to every object.

    Hi! I'd say, install the 5.7 package (http://download.qt.io/archive/qt/5.7/5.7.1/qt-opensource-linux-x64-5.7.1.run) and then use the included maintenance tool to upgrade the Qt libraries etc, but not Creator.

    See flags QIODevice::OpenMode. With QIODevice::WriteOnly the device will be truncated if possible. What you want is QIODevice::Append.

    More than likely you have a read issue like @vronin says. You definitely don't need to delay between sends.

    Thanks, it's likely a bug in the rendering of the html fragment. You should check the bug report system to see if there's anything related.

    @Anand-MN Well have you considered just using one of the many available for free ? You could set up a virtual linux server and have it work pretty fast.
