How to show TextCtrl selection when it isn't focused?

I just implemented FindReplaceDialog for my TextCtrl, but if the Find dialog has focus, you can’t see the text selected with SetSelection. I would think the selection would change from blue to grey or something, rather than just not appear.

Code altered from the demo:

def OnSearch(self, event):

	self.findData = wx.FindReplaceData()

	self.foundIndex = None

	self.lastString = None

	dlg = wx.FindReplaceDialog(self, self.findData, "Find")

	self.BindFindEvents(dlg)

	dlg.Show(True)

def BindFindEvents(self, win):

	win.Bind(wx.EVT_FIND, self.OnFind)

	win.Bind(wx.EVT_FIND_NEXT, self.OnFind)

	win.Bind(wx.EVT_FIND_REPLACE, self.OnFind)

	win.Bind(wx.EVT_FIND_REPLACE_ALL, self.OnFind)

	win.Bind(wx.EVT_FIND_CLOSE, self.OnFindClose)

def OnFind(self, evt):

	#print type(evt)

	#print dir(evt)

	#print repr(evt.GetFindString()), repr(self.findData.GetFindString())

	eventMap = {

		wx.wxEVT_COMMAND_FIND : "FIND",

		wx.wxEVT_COMMAND_FIND_NEXT : "FIND_NEXT",

		wx.wxEVT_COMMAND_FIND_REPLACE : "REPLACE",

		wx.wxEVT_COMMAND_FIND_REPLACE_ALL : "REPLACE_ALL",

		}

	et = evt.GetEventType()

	if et in eventMap:

		evtType = eventMap[et]

	else:

		evtType = "**Unknown Event Type**"

	if et in [wx.wxEVT_COMMAND_FIND_REPLACE, wx.wxEVT_COMMAND_FIND_REPLACE_ALL]:

		replaceTxt = "Replace text: %s" % evt.GetReplaceString()

	else:

		replaceTxt = ""

	#print ("-i- %s -- Find text: %s  %s  Flags: %d  \n" %

	#			(evtType, evt.GetFindString(), replaceTxt, evt.GetFlags()))

	#if evtType == 'FIND':

	if self.foundIndex == None or self.lastString != evt.GetString():

		self.foundIndex = self.findFirstTime(evt.GetString())

	else:  #an index had already been found, so we need to start searching from that point

		foundIndex = self.findAgain(evt.GetString(), self.foundIndex+1)

		#only set a new self.foundIndex if foundIndex isn't None

		if foundIndex:

			self.foundIndex = foundIndex

	if self.foundIndex:

		self.lastString = evt.GetString()

		self.cmdLogTextBox.ShowPosition(self.foundIndex)

		self.cmdLogTextBox.SetSelection(self.foundIndex, self.foundIndex + len(evt.GetString()))

		self.cmdLogTextBox.SetFocus()

def OnFindClose(self, evt):

	#print "-i- FindReplaceDialog closing...\n"

	evt.GetDialog().Destroy()

def findFirstTime(self, stringToFind):

	try:

		return self.cmdLogTextBox.GetValue().index(stringToFind)

	except ValueError:

		return None

def findAgain(self, stringToFind, indexToStartSearchingAt):

	try:

		return self.cmdLogTextBox.GetValue().index(stringToFind, indexToStartSearchingAt)

	except ValueError:

		return None
