Subclassing in a class

[abdul]

I have a label class that needs to subclass its parent window whenever it's initialized. Now when I declared the window procedure inside the class and then try to set the window procedure to new one, I have to call like "&myclass::WindowProc" but that gives me an error message because I have to pass the arguements of WindowProc with it too. If I declared WindowsProc outside of the class then it'll work using "&WindowProc" but I won't be able to access any of the myclass members from inside the procedure and I won't recieve any message after that in my real window procedure because then I'll have two window procedures handling the messages for same window at the same time. I want to make the first method (declaring the window procedure as a function if the class and then somehow correctly passing its address as the new window procedure - not call the actual window procedure includign its arguements) work but maybe you have any idea of how to get it working that way.

It has nothing to do with parameters. It's just that normal class members are of calltype __thiscall and can therefore not be used as __stdcall (= CALLBACK) functions. You can use a static class member, which still can't access member variables but at least has access rights (so if you pass a pointer to the class object to the function and it stores it somewhere you can access private members).

I guess that will be a bit messy so I thought of another method. I ask the user (who is using the class) to just pass whatever it gets in the messages "WM_DRAWITEM" and "WM_MEASUREITEM" to one of the class functions and then it performs all the measuring and drawing. It'll then also be able to access the class' member functions. Sounds good idea?

Not if you actually want to distribute that class.
