That definitely sounds like a bug to me at your end. I've only used the integer version of the signal, and I've never got double signals like that. In my sources (C:\qt\4.8.3\src\gui\widgets\qcombobox.cpp(1258)), the two different signals are always sent together, so you should only get one as well. I've used most versions since 4.3. What is your configuration, version, OS, etc? Are you supplying your own model to the combo box? Do the Qt test programs have the same problem - I assume there must be one with a slot for either of these signals?
