A simple standard QML / controls app on Android we can use TextEdit or TextField components and those automatically enable the native virtual keyboard.

While typing from a real keyboard causes the 'text' variable to be changed in those components, this does not seem to happen on Android.

Code that responds to what the user typed (changing a button to enabled, for instance) will not get triggered until the focus leaves the widget.

I expect that the virtual keyboard behaves basically the same as a full size keyboard to the underlying application. Hiding from the app what input device is used.
