Is this a wx bug?

[Chris Carlen]

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."""

import wx

class MouseEventFrame(wx.Frame):
     def __init__(self, parent, id):
         wx.Frame.__init__(self, parent, id, title="Listing 3.3", 
size=(300, 100))
         self.panel = wx.Panel(self)
         self.button = wx.Button(self.panel, label="Not over", pos=(100, 
15))
         self.Bind(wx.EVT_BUTTON, self.OnButtonClick, self.button)
         self.button.Bind(wx.EVT_ENTER_WINDOW, self.OnEnterWindow)
         self.button.Bind(wx.EVT_LEAVE_WINDOW, self.OnLeaveWindow)

     # This is not critical to demonstrating the 'bug', but just provides
     # feedback that the wx.EVT_BUTTON events are working correctly
     # in relation to entering/leaving the button window.
     def OnButtonClick(self, event):
         if self.panel.GetBackgroundColour() == "Green":
             self.panel.SetBackgroundColour("Red")
         else: self.panel.SetBackgroundColour("Green")
         self.panel.Refresh()

     def OnEnterWindow(self, event):
         self.button.SetLabel("Over")
         event.Skip()

     def OnLeaveWindow(self, event):
         self.button.SetLabel("Not over")
         event.Skip()


if __name__ == '__main__':
     app = wx.PySimpleApp()
     frame = MouseEventFrame(None, id=-1)
     frame.Show()
     app.MainLoop()
