如何確保我的自訂 Tkinter 文字小工具綁定在內建綁定之後執行？

<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
