Does QML have a numeric picker wheel ui element? >Since Qt 5.5 Tumbler<http://doc.qt.io/qt-5/qml-qtquick-extras-tumbler.html> >is free. I just built and ran the Qt Quick Enterprise Controls and I saw tumbler. I am glad it is free for others to use too. The PieMenu looked great too. >Anyhow writing one in QML is quite easy using a PathView. Here is a component That was one of my concerns about QML. Initially it looks like you could only use what Qt had created for you, If something like a tumbler did not exist I assumed you were out-of-luck. I need to research PathView and what it takes to create a new custom control. I have wanted to try creating UI elements in QML then display them in a widget from my C++ Qt widget app. I do not know if this is possible; launching a QML ui then and receiving what the user selects from the QML UI. It may be worth the effort. If I could mix some QML with my widget app it could be a better solution compared to writing (and maintaining) two (2) native UI numeric pickers, one for Android, and one for iOS. So far I have one Qt widget codebase supporting Android, iOS, Linux, OS X, and Windows desktops except for a few things like Bluetooth, sending email, UIAlertView ( QMessageBox looks terrible on iOS ) and such. If I start adding native UI interfaces for Android and iOS I start to lose benefits of Qt. >Mixing Qt Widget and QML is possible. Look at this >blogpost<http://www.ics.com/blog/combining-qt-widgets-and-qml-qwidgetcreatewindowcontainer>. I just ran across that example. It worked once I put the QML file into a resource. However that example does not interact with C++. I was hoping to find an example that would demonstrate how I could read the QML state from C++ ( or visa versa ). I assume ta QML toggle button could raise a toggled signal that a C++ handler could react to? Or C++ could change the state of the QML toggle button?
