[Glade-users] combobox question

[ashats at hotmail.com (Arthur Shats)]

OK, I just tried a simple example first, but it gives me a warning:
Here is my Python code for filling in comboBox, etc. :
 
store = gtk.ListStore(str)
 
store.append(["test1"])
store.append(["test2"])
store.append(["test3"])
store.append(["test4"])

combo = wtree.get_widget('myComboBoxFromGlade')
combo.set_model(store)
if  type(combo) == gtk.ComboBoxEntry :
      combo.set_text_column(0)   ### this gives me a warning, see bellow !!!!!!
elif   type(combo) == gtk.ComboBox :
      cell = gtk.CellRendererText()
      combo.pack.start(cell, True)
      combo.add_attribute(cell, 'text', 0)
 
At run time, my combo box seem to function OK, but I get this warning:
GtkWarning: gtk_combo_box_entry_set_text_column: assertion `entry_box->priv->text_column == -1' failed 
combo.set_text_column(0)
 
Why does this warning comes up, should I be worried about it and is there a way to fix it?
Thanks,
Arthur.
