Ever heard of QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling); (to be set before creating the QApplication instance).

How does it help, when displaying a tiny file selection dialog on an Android device? https://bugreports.qt.io/browse/QTBUG-42491 https://bugreports.qt.io/browse/QTBUG-42491

  These file dialogs are not for mobile! But it's easy to make your own ones, please see: https://gitlab.com/eql/EQL5-Android/blob/master/screenshots/REPL-file-dialog.png https://gitlab.com/eql/EQL5-Android/blob/master/screenshots/... The above is on an android tablet; but it displays perfectly fine on phones, too. Just see the sources of the above project for implementing such a dialog: https://gitlab.com/eql/EQL5-Android/blob/master/examples/my/qml/ext/FileBrowser.qml https://gitlab.com/eql/EQL5-Android/blob/master/examples/my/... https://gitlab.com/eql/EQL5-Android/blob/master/examples/my/qml/ext/FileDelegate.qml https://gitlab.com/eql/EQL5-Android/blob/master/examples/my/...

    Which proves you failed to understand my point, C++ Widgets don't work everywhere, only QML.

      That depends on your screen size! But of course I would never use QWidgets on mobile, with the only exception of direct painting (using a QPainter on a plain QWidget). QML is easier anyway, and gets better with every version...

        Not all Qt developers are happy to be forced to use QML, which again, was my point to start with. C++ Widgets should be able to offer a mobile friendly version of themselves. Which was actually a point that was discussed for the Qt roadmap at Qt World Summit 2017.

        OK, I understand your point. Good luck, then!

        Thanks, but actually I don't use Qt anymore, that bug and a few other ones in 5.4 lead me to use Java and C++/CX for the UI, with common business logic in C++, in a MVVM approach. The approach of re-doing in QML standard UI components is not appealing.
