Hello, Is there any wxCanvas documentation? I 'd like to use this class to perform drawning application but imposible to find it referenced anywhere. However with devcpp wxwindows pack, there is a wxCanvas exemple that compiles and executes rigth; The problem is when I try to add more wxCanvasObject in my canvas during the application living (for example on a trigger like select a menu ), my program crashes. Perhaps I miss the way to use wxCanvas... Thank you for your help.
