Hello!

I'm writting my first application (without tutors) and having problems to run it.
Before anything apeares it ends with Segmentation fault.

the structuture is something like this:
I have written a dialog with some buttons, lineedit, a table, etc.
when i run the program (just the GUI) it works fine.
so i make one more step.. I include some of my classes.

when i compile the project it doesn't show any errors. but when i run it... BOOM!
I just put one line in init():
myClass= new MyClass();

i was looking for some getting started on how to add your own classes but found nothing useful.

Another question: My own classes have to be derivered from QObject?
