This looks pretty simple even for a newbie like me, but somehow I can't associate
the following line in wndProc:

Window* wnd = hwnd in Window._windows;

to the class...

Inside the class I'm using the CreateWindowA WinAPI, which returns the needed
HWND, but how do I put this HWND into the _windows array?

Is there a chance to get a minimalistic but full working example?


Also somehow the compiler (GDC) always wants 'main' but afaik in gui apps it
should be 'winmain'...


Thanks says a newbie (to D...)
