Hi! I'm observing some strange interaction between wxPython and win32ui on Windows 7 PCs.
I've been using DDE code from Pythonwin which in turn uses win32ui. When I use win32ui and SetToolTipString from wxPython in the same program, the Python interpreter will not exit any more (until it's killed from the task manager or by closing the console window.) See below for the code. If I omit "import win32ui" or "panel.SetToolTipString(...)", then the interpreter will exit as expected. I've posted the problem on the wxPython mailing list and Robin Dunn suggested the workaround of calling wx.Exit(), which is more or less the equivalent to killing the interpreter. Robin's comment: > It seems that something that is done during the import of win32ui > is conflicting somehow with what is done when a wxToolTip object > is created.

Calling wx.Exit() works for me, but it's not a nice way to finish... The versions: pywin32 build 216 wxPython 2.8.12.0 or 2.8.11.0 Python 2.7 (same with 2.6 and an older version of wxPython and pywin32) With Windows XP or 2000 everything works as expected. I think I had the problem already with Vista, but I'm not sure. One user has reported that the code works for him under Win7 with Python 2.6.5. Regards, Dietmar import wx import win32ui class MyFrame(wx.Frame): def __init__(self, parent): wx.Frame.__init__(self, parent, -1, "test frame") panel = wx.Panel(self, -1) panel.SetToolTipString("test") self.Bind(wx.EVT_CLOSE, self.OnCloseWindow) def OnCloseWindow(self, event): self.Destroy() import sys app = wx.App() frame = MyFrame(None) frame.Show(True) app.MainLoop() print "calling sys.exit()" sys.exit() _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
