title: Creating a Treeview with Checkboxes
body: <p>I am trying to build an application based on the following usage example (<a href="https://stackoverflow.com/questions/5104330/how-to-create-a-tree-view-with-checkboxes-in-python">How to create a tree view with checkboxes in Python</a>). </p>
  
  <p>This example builds a <code>Treeview</code> with checkboxes using the <code>Tix</code> library. However, when I run this example, whenever a <code>Checkbox</code> is checked, the text label of that box disappears. </p>
  
  <p>Could someone help me to avoid the behaviour mentioned just above?</p>
  
  <pre><code>import Tix
  
  class View(object):
      def __init__(self, root):
          self.root = root
          self.makeCheckList()
  
      def makeCheckList(self):
          self.cl = Tix.CheckList(self.root, browsecmd=self.selectItem)
          self.cl.pack()
          self.cl.hlist.add("CL1", text="checklist1")
          self.cl.hlist.add("CL1.Item1", text="subitem1")
          self.cl.hlist.add("CL2", text="checklist2")
          self.cl.hlist.add("CL2.Item1", text="subitem1")
          self.cl.setstatus("CL2", "on")
          self.cl.setstatus("CL2.Item1", "on")
          self.cl.setstatus("CL1", "off")
          self.cl.setstatus("CL1.Item1", "off")
          self.cl.autosetmode()
  
      def selectItem(self, item):
          print item, self.cl.getstatus(item)
  
  def main():
      root = Tix.Tk()
      view = View(root)
      root.update()
      root.mainloop()
  
  if __name__ == '__main__':
      main()
  </code></pre>
