On Android platform the keyboard rect is unknown, because is an external service.
The only way to be sure the user will see the entire control and its content,
is to create a dummy transparent Android native widget in the same position and 
with the same size as the qt control, I pass that widget to the keyboard service, 
then the Android window manager will do the magic for me, it will pan the screen or 
it will resize it if necessary.
Please check the video I posted on youtube [1].
