wxPython: How to get letter colour from TextCtrl

[D. Schramm]

Hello,

I've got a problem getting the colour of a single letter within the 
TextCtrl widget:

letterstyle = wx.TextAttr()
self.p1.GetStyle(self.p1.XYToPosition(0,0),letterstyle)
color = letterstyle.GetTextColour()
print color

This should display the colour value of the very first letter in the 
very first line of the TextCtrl. But no matter what I try, it always 
returns the value (-1, -1, -1, 255).

Any help?

Thanks in advance,
