[wxPython] TextCtrl: how to highlight an entire line?

[dodle]

I'm trying to highlight a whole line when the left mouse button is pressed within a wx.TextCtrl. I don't know if I am going about it the right way, but here is my code so far:

lineselect.py:

#! /usr/bin/env python

# Select the entire line when the left mouse button is pressed

import wx

class MainWindow(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, (100,200),
style=wx.DEFAULT_FRAME_STYLE & ~(wx.RESIZE_BORDER|wx.RESIZE_BOX|wx.MAXIMIZE_BOX))

self.Center()

self.display_area = wx.TextCtrl(self, -1, style=wx.TE_MULTILINE|wx.TE_READONLY)

text = "Line 1\nLine 2\nLine 3\nLine 4\nLine 5"
self.display_area.SetValue(text)

wx.EVT_LEFT_DOWN(self.display_area, self.selectLine)
self.POS = wx.EVT_MOTION(self.display_area, self.mousePOS)

def selectLine(self, event):
"""Uses the mouse position to find which line to highlight"""
self.display_area.SetFocus()
print self.POS

def mousePOS(self, event):
"""Finds the position of the mouse"""
self.POS = event.GetPosition()
return self.POS

class LineSelect(wx.App):
def OnInit(self):
frame = MainWindow(None, -1, "Line Select")
frame.Show(True)
self.SetTopWindow(frame)
return True

app = LineSelect(0)
app.MainLoop()
