Adding Scroll bar to Wx.TextCtrl with autocomplete

Dear users,
I had some doubts about wx.TextCtrl Widget with autocomplete

1.Can I add scroll bar to the choice list of wx.TextCtrl Widget with autocomplete.

2.Also how to popup the choice list automatically when needed ?

3.Is this feature of Autocomplete with wx.TextCtrl is backward compatible?

Sample script which i got from others and modified by me is attached here.

The script is working fine without scrollbar.

I am using Windows 7 , Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)] on win32 and wxpython 3.0.2.0

Expecting some help in this regard,

With thanks all the support,

Sibu.N.L
