Topic: Qt Android + A C ++ + QML - IME

All greetings! I write application for Androida, sheaf Qt/C ++ + QML. One more device is connected To the device as the keypad. I.e. in adjustments of Androida this one more input equipment (IME - Input Method Editor). All anything, but I should change program at first to one keypad, then on another, depending on on what data entry field current focus. Here http://doc.qt.io/qt-5/qinputmethod.html does not implement. Clearly that through XXXHints it is possible to specify filters (only numbers, only letters etc.)  from it Qt shows the necessary keypad. But how to switch program to the keypad from other device, I can not understand. There are ideas?
