Jules, Jucer adds the following to the end of the .cpp file it creates:
//[MiscUserCode] You can add your own definitions of your custom methods or any other code here...
Would it be possible for you to add a similar field right at the top of the class underneath the header definitions? This is for other user class definitions, etc. I realize you could just move the [MiscUserCode] tags to the top, but then you wouldn’t be able to add anything at the end of the class.
