How to set a wx.textctrl can editable or readonly?

[Hako]

Hello All,


I have  a function to set readonly or editable of a textctrl. I'd like
to make the textctrl initial set readonly and use other event funciton
to set editable of the textctrl but it always can editable. How to set
a textctrl can editable or readonly?

Any Ideas? (see short snippet below)
Thanks.
-----------------------------------
self.tcFirstName = wx.TextCtrl(id=wxID_FRAME1TCFIRSTNAME,
              name=u'tcFirstName', parent=self.panel2, pos=wx.Point(16,
32),
              size=wx.Size(168, 24), style=0, value=u'')
self.setForm()

def setForm(self):
              self.Readonly("ro")

def Readonly(self, flag):
	if flag=="ro":
		self.tcFirstName.style=wx.TE_READONLY
		self.tcFirstName.Refresh()
		self.tcFirstName.SetBackgroundColour(self.panel1.GetBackgroundColour())

	else:
		self.tcFirstName.style=0
		self.tcFirstName.Refresh()
		self.tcFirstName.SetBackgroundColour((255,255,255))

# Other event function set textctrl can editable
def OnBAddButton(self, event):
	self.Readonly("o")
