Virtual Keyboard for Pi with Auto Hide

I use PyGObject to create a user interface that will run on the 7-inch official RPi touch screen connected to the Pi 3 running Raspbian. Within this interface, the user interface will need an on-screen keyboard. Two virtual keyboard programs for Pi: ​​Matchbox Keyboard and Florence.

The problem is that I want to simulate the behavior of the smartphone keyboard as much as possible, but I don’t know how to do it. What I want to do is similar to this , except that I want the keyboard to hide automatically and be on top of the main window. How can I do that?

EDIT: I tried both of these programs and couldn't figure out how to achieve this. I can’t find the auto popup option in the Matchbox Keyboard, and some people say that it has this feature ( here ), others say that it doesn’t ( here ). I assume that some Linux desktop administrators support this feature, but not LXDE on Pi.

Florence seems promising because it has an auto-hide option that sounds like it will do what I want, but when I select it, it doesn't seem to work.
