Summary: Arguments to canvas object (cnv) do not take effect
Initial Comment:
The canvas object seems to take arguments happily enough - while I
could not find this documented, I discovered what went where by trying
"cnv a b c d e f g h..." and checking where they ended up in the
properties. This worked, but while the arguments appear in the
properties, they do not actually "show up" in the canvas until the property
window is closed again.
I've attached a patch that demonstrates this behavior.
(I was hoping to build a "canvas generator" that would save me the
trouble of opening property windows to set dimensions or a recieve
symbol that could be used with Joao Miguel Pais's "gui-edit" abstraction.
But the receive symbol does not start functioning until the props are
opened, then closed.)
Also, the first 3 arguments do not seem to do anything (they'd logically
control "selectable size" and the x and y dimensions of the canvas).

this is, because you are using wrong arguments and not
because of a bug in [cnv].
attached is a working patch (which uses more arguments than
the original one)
there are 4 possibilities to "reverse engineer" the
arguments of an object:
1) read the help (won't help you with [cnv])
2) read the pd-list (ask! chances are high that somebody
already solved your problem)
3) read the patch (save a patch with the object as you would
like it; open the patch with a text editor; look which
arguments are used; understand what the arguments mean)
4) read the source
esp. #3 is a very simple and efficient and good way to
discover the arguments of an object (the object usually
knows best which arguments it needs)
