カスタム Tkinter テキスト ウィジェット バインディングが組み込みバインディングの後に実行されるようにするにはどうすればよいですか?

<code class="python"># Modify the bindtags to rearrange the order
entry.bindtags(('Entry', '.entry', '.', 'all'))</code>

<code class="python"># Create a new bindtag "post-class-bindings" after the class bindtag
entry.bindtags(('.entry','Entry','post-class-bindings', '.', 'all'))

# Bind your custom events to "post-class-bindings"
entry.bind_class("post-class-bindings", "<KeyPress>", OnKeyPress)</code>

<code class="python">import Tkinter

def OnKeyPress(event):
    value = event.widget.get()
    string="value of %s is '%s'" % (event.widget._name, value)
    status.configure(text=string)

root = Tkinter.Tk()

entry1 = Tkinter.Entry(root, name="entry1")
entry2 = Tkinter.Entry(root, name="entry2")
entry3 = Tkinter.Entry(root, name="entry3")

# Three different bindtags
entry1.bindtags(('.entry1', 'Entry', '.', 'all'))
entry2.bindtags(('Entry', '.entry2', '.', 'all'))
entry3.bindtags(('.entry3','Entry','post-class-bindings', '.', 'all'))

# Bind the first two entries to the default bind tags
entry1.bind("<KeyPress>", OnKeyPress)
entry2.bind("<KeyPress>", OnKeyPress)

# Bind the third entry to the "post-class-bindings" bind tag
entry3.bind_class("post-class-bindings", "<KeyPress>", OnKeyPress)

# ... Continue with your GUI code
