I have a GUI application that accepts some text, running on pi3 under resbian .
I invoke on-screen keyboard ( matchbox) from terminal. But by default it always come on top of the screen. I want it to bring on lower half side.
How can I achieve this ? Exactly same question is here viewtopic.php?t=179613
but nothing has been explained except that he used wmctrl , and the question is marked 'resolved.'
