OK. Got it. You want an "auto-growing" text control that extends
itself (and the surrounding parent) vertically as your adding new
lines.

I think, there's nothing "ready made" in the wxWidgets-box. You'll
probably have to derive a class from wxTextCtrl, use the
wxTE_PROCESS_ENTER-style, override the handler for the "Enter"-key
and then add the initial height every time the user hits enter (or
do some calculation with text extent). Your wxTextCtrl will then have
to call vSizeToContent() (see [1] below that I stole somewhere from
one of Vadim's examples) or something likewise that makes it fit
snugly around the child windows.

Good luck.
