Avoid click to get out of wxPython TreeCtrl in a Notebook
Question: Below is a very simple wxPython code creating a Notebook inside which are
several panels containing TreeCtrl objects.

Using it, I get a behavior I would like to avoid:

When I click in a tree, then I cannot switch directly to another page of the
notebook without clicking first outside the tree. This means that it needs two
clicks to change the notebook page: One to get outside the tree, another to
switch the page.

I would like to be able to do this in one single click.

The code:

    
    
    import wx
    
    class TestFrame(wx.Frame):
    
        def __init__(self):
            wx.Frame.__init__(self, None, wx.ID_ANY)
    
            # Create the notebook
            notebook = wx.Notebook(self)
    
            # Put panels in the notebook
            notebook.AddPage(TestPanel(notebook), "Page 1")
            notebook.AddPage(TestPanel(notebook), "Page 2")
    
            # Display the window
            self.Show(True)
    
    
    class TestPanel(wx.Panel):
    
        def __init__(self, parent):
            wx.Panel.__init__(self, parent)
    
            # Create the sizer
            sizer = wx.BoxSizer(wx.VERTICAL)
            self.SetSizer(sizer)
    
            # Create the tree
            tree = wx.TreeCtrl(self)
            sizer.Add(tree, 1, wx.EXPAND)
    
            # Create nodes in the tree
            root = tree.AddRoot("root")
    
            tree.AppendItem(root, "item 1")
            tree.AppendItem(root, "item 2")
            tree.AppendItem(root, "item 3")
    
            # Expand the root node
            tree.Expand(root)
    
    
    if __name__ == "__main__":
    
        # Create an application without redirection of stdout/stderr to a window
        application = wx.App(False)
    
        # Open a main window
        frame = TestFrame()
    
        # Launch the application
        application.MainLoop()
    


Answer: This looks like [this bug](http://trac.wxwidgets.org/ticket/16055) which
should be fixed in 3.0.2. If you're using an earlier version, please upgrade.
