Problems with wx.CheckListBox on OSX

wxPython Users
1

As far as I can tell, if a checkbox is ever checked by the user, is it
forever reported as being checked, whether the user unchecks it or
not. Sample script below; try checking some boxes, and then
unchecking some. Anything that you check and later uncheck is
(programatically) reported to be checked regardless of the current
state of the checkbox.

Doesn't seem to be a problem on windows; have not checked Linux yet.
My build of wxwidgets/wxpython on OSX is 2.9.1.1 (osx-carbon-unicode).

Sample script below:

import wx

class TestPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent, -1)

        sampleList = ['one', 'two', 'three', 'four']

        self.lb = wx.CheckListBox(self, -1, wx.DefaultPosition,
(200,200), sampleList)

        self.Bind(wx.EVT_CHECKLISTBOX, self.EvtCheckListBox, self.lb)

    def EvtCheckListBox(self, evt):
        print "The current selections are: "+str(self.lb.GetChecked())
        evt.Skip()

# start the app
app = wx.App()
frame = wx.Frame(None)
panel = TestPanel(frame)
frame.Show(True)
print wx.version()
app.MainLoop()

As a follow-up; neither Windows or Linux (same version of wxPython/wxWidgets) exhibit this behavior.

I don't have a Carbon build installed currently, but it's working fine for me with a 2.9.2.4 Cocoa build. If it's still not behaving correctly for you with a 2.9.2.4 Carbon build then please create a ticket for it at trac.wxwidgets.org.

Still not working for 2.9.2.4 osx-carbon (classic); it does work in
the cocoa build. Created ticket at wxTrac has been migrated to GitHub Issues - wxWidgets
