@Raadush: I put on my magic wizard hat, which allows me to see invisible code. My friends high_flyer and amleto don't have a hat like this one, so they are at a disadvantage.

You have about 300 member variables in your class. Are you initializing every one of them to some known, acceptable value in your constructor - especially those QList<int> * ones? Or are you just hoping that when you use one of them it will magically (like my hat) have a good enough value that Qt can do something with it?

Are you confusing QList<int> * with QList<int *> and using one when you mean the other? Likewise with the QString * member variables. What's the point of a pointer to a QString?
