Re: [PD] Is there a way to get the canvas my object is at runtime ?

You would only need to rewrite the function that max used (since it won't exist otherwise anyway), and have it retrieve the value from the class struct instead.

And also add a line to your *_new method where you initialize the t_canvas* field in your struct using canvas_getcurrent().

hi,

thanks for your answer, but I was wondering if there is a way to
retrieve it without saving it.
I'm porting a Max lib to Pd which uses such a thing in Max (which
is possible since SDK 6).
If it's not possible I would have to rewrite *a lot* of the lib
code. :-(

    You could save the pointer in your class struct during the new
    method.

        Hi,

        I would like to retrieve at any time the pointer to the
        t_canvas containing my object.
        Is that possible ?
        I know I can retrieve it with something like :
            t_glist *glist=(t_glist *)canvas_getcurrent();
            t_canvas *canvas=(t_canvas*)glist_getcanvas(glist);
        in the myobject_new() method.

        But the same give me a (nil) t_canvas pointer outside the
        new() method.

        Thanks in advance.

        Antoine
