Question about implementing multi-thread-input in TextCtrl?

Hi all,

Does someone know how to implement multi-thread-input in the TextCtrl?
I mean, I use a thread to write text to textctrl, and I also can

input without changing the insertion focus.

I want to make a collaboration edit effect and I do not know how to.

Thank you for your reading.
