Hi:
#!/usr/bin/env python
"""From listing 3.3 in 'wxPython in Action'
Demonstrates that something funny happens when you click&hold in the
frame, then drag the mouse over the button window. The
wx.EVT_ENTER_WINDOW event is missed. The wx.EVT_LEAVE_WINDOW event is
NOT missed when you click&hold the mouse button over the button, and
leave the button window."""
