title: PyGTK treeview - same column - with checkbox or text
body: <p>I wanted to ask, if someone knows how to create a treeview, which consists of two columns. 
  The first column is a description column, and the second column consists depending on the leaf, of a text or checkbox. I have to program it with pygtk version 2.0 (!).</p>
  
  <p>Like</p>
  
  <pre><code>Column 1,          Column2
  Test_1
      RPM            2700
      Model          NameXXX
      Active         [X]
  Test_2
      RPM            1000
      Model          NameXXX
      Active         [ ]
  </code></pre>
  
  <p>How should I program column2?</p>
  
  <pre><code>test_data = [
          { 'column0' : 'test00', 'column1' : 'test01', 'f': '#000000', 'b': '#FF00FF' },..]
  column0 = gtk.TreeViewColumn("Column 0", gtk.CellRendererText(), text=1, foreground=2, background=3)        
          treeview.append_column(column0)
  </code></pre>
  
  <p>the code before allows the user to set the foreground and background depending the row. i would like to do the same with the cell renderer, i hope you can help me :/</p>
  
  <p>Thanks!</p>
