[python-win32] OnCtlColor not working?

[Greg Ewing]

Has anyone successfully used the PyCWnd.OnCtlColor
virtual function to change the appearance of a
control?

The program below tries to use it to set the colour
of the text in a PyCButton. My OnCtlColor method gets
called, but it doesn't have any effect on the appearance
of the button.

Also, if I attempt to return a PyCBrush from the
OnCtlColor method as the docs suggest, I get
"TypeError: An integer is required" errors.

Am I doing something wrong?

#--------------------------------------------------------------------------------

import win32con, win32ui
from pywin.mfc.object import Object

class MyFrame(Object):

	def OnCtlColor(self, dc, btn, typ):
		print "MyFrame.OnCtlColor:", self ###
		dc.SetTextColor(0x0000ff)
		# Doing the following causes "TypeError: An integer is required"
		#b = win32ui.CreateBrush()
		#b.CreateSolidBrush(0x00ff00)
		#return b

frame = MyFrame(win32ui.CreateFrame())
frame.CreateWindow(None, "Test", win32con.WS_CAPTION,
	(100, 100, 300, 300))
button = win32ui.CreateButton()
style = win32con.BS_CHECKBOX
button.CreateWindow("Hello", style, (20, 20, 100, 40),
	frame, 0)
button.ShowWindow(win32con.SW_SHOW)
frame.ShowWindow()
app = win32ui.GetApp()
app.Run()
