At the moment you can't. wxWidgets doesn't support setting wx.HSCROLL 
except when the underlying TextCtrl is being created.

I've enclosed a version of PythonCard/components/textarea.py - you can 
(temporarily) replace your copy with this, and then you can use the 
resourceEditor to set hscroll (to 1 or 0)

Problem is that style isn't changeable after being created (unless I missed 
something in wxWidgets docs).

Here are the changes (or just use the attached file)
