Ok, it looks like the wrong DeleteAllPages method is being called on
Windows, it works fine on the other platforms.  On Windows it is calling
only the base class method and so the tabs in the native widget are not
being removed. I'll fix that problem for the next release.  In the
meantime you can call DeletePage for each tab.


    def DeletePages(self, event):
        #self.testNotebook.DeleteAllPages()
        while self.testNotebook.GetPageCount():
            self.testNotebook.DeletePage(0)
   
        otherPanel = wx.Window(self.testNotebook)
        self.testNotebook.AddPage(otherPanel, "NewPanel")
