What is the API equivalent of SetWindowCallback?
I would like to do some more advanced callback stuff, can't seem to find it's equivalent in the Win32 API docs.

OldProc.l=SetWindowLong_(hwnd,#GWL_WNDPROC,@MyCallbackProc())

Code: Select all
SetWindowLong_(hWnd, #GWL_WNDPROC, @YourProcHere())
EDIT: Why, oh why am I always too late!?!?!?

Just type faster!
... anyway, we both forgot to say that you should add
Code: Select all
ProcedureReturn CallWindowProc_(OldProc,hwnd,message,wParam,lParam)
for anything your callback doesn`t handle.

I guess I should simply start being more self-confident and stop using 'preview' that often
Code: Select all
ProcedureReturn CallWindowProc_(OldProc,hwnd,message,wParam,lParam)
What about
Code: Select all
ProcedureReturn DefWindowProc_(hWnd, msg, wParam, lParam)
alternatively ?

SetWindowCallback() is not equal to the hook described here (afaik).
I believe SetWindowCallback() is resetting the windowclass procedure.
So all windows with the same class will 'suffer'.
The hook described above failed when i tried this in earlier PB versions.
Hopefully something has changed and will let us use hooks.

Hm, I'll have to try SetWindowClass too.
