In a C++03 conformant compiler, things should work like so: new C() - default construct (C::m is zero-initialized).New C - default construct (C::m is zero-initialized) New B() - default construct (B::m is uninitialized) New B - default construct (B::m is uninitialized) In a C++98 compiler, the following should occur: Struct B // non-POD, default-initialising m In C++2003 a 3rd type of initialization, value initialization was added.In C++1998 there are 2 types of initialization: zero and default.Sometimes the memory returned by the new operator will be initialized, and sometimes it won't depending on whether the type you're newing up is a POD (plain old data), or if it's a class that contains POD members and is using a compiler-generated default constructor. Much of the following is taken from comments made to an "Old New Thing" article. Let's get pedantic, because there are differences that can actually affect your code's behavior. I have managed to successfuly use MV by reading the official book and using the Qt help together with the examples. Sometimes I pass the entire model.Īside from the official book's chapter on MVC, and the on-line tutorial here, what are some other resources to a MVC newcomer in Qt? Other widgets whatever data they need as interfaces, containers, structs, delegates, etc. I generally hold the model inside the main window and pass You should still apply OO design rules when using Qt. Inside of the class itself should I be strictly encapsulating data, or making it friendly to like-classes? Does this help with accessability? I prefer number 3 unless the ui class is really big because it means one less new allocation and results in less Hold said class in a regular member variable.Hold a pointer to said class in your class.ui you should include the uic (created by Qt Creator in your case) generated header file in your widget class' header file, and then you have three options: I assume that you mean "include the header file": when creating a widget with an associated.
