Pythonista special key row problems in IOS 14

dthomson

It appears IpadOS 14 broke the special key row in Pythonista. After editing for a short while the center section of keys disappears. A while later the remaining keys shrink further to the sides. It also appears the cursor positioning by sliding over the key row does not work in the center portion, even when the keys are still showing.

@cvp I learn a lot adapting your scripts to my needs !
You will find after this message my/your script to add a keyboard icon in the titlebar to call my script to add my special key row to the keyboard.
The system is rather practical, but to make the handling as transparent as possible : when I add my key row, I hide the keyboard with tv.endEditing(True), and I would like to make it reappear with my special key row : but I’ve not found a command as simple as tv.startEditing 🙁 ; it’s perharps possible to simulate a touch in the TextView, but I neither can’t find a solution to do it 🥶
After several hours of searching, I throw in the towel and ask for help…🥵

I must admit with humulity that the most complex part of this code comes from @JonB 🤫

@cvp Thanks a lot ! I’m happy to see that I progress slowly…
I had found textView().becomeFirstResponder() but couldn’t find to witch element it had to be applied. The _get_editor_tab is not documented ! To find it, do you open editor.py in the site-packages of Standard Library ?
It's very instructive 🤓, I'm going to end up managing on my own. 😉

Yes sir

the problem gets worse, and don't ask me how it happens...

I begin to panic

With me on iOS 14.3 / iPad it seems to have something to do with the “darkmode” setting. When running in “light” mode the problem did not occur yet. When I switch back to dark mode, the extra keyboard row splits again after switching between file tabs in the editor.
so, maybe use light mode for Pythonista?

I don't think so, see my first examples in the topic.
