Hmmm, upon thinking about this, this makes me think that the tkwidgets library should include the tk canvas primitives like "rectangle", "arc", "polygon", "line", etc. The idea would be a simple access to Tk drawing rather, which is a different mission than Pd's graphical data structures. You can read more the Tk canvas here:
http://tcl.tk/man/tcl8.4/TkCmd/canvas.htm
I would love to have collaborators to develop tkwidgets library completely, for example, the canvas.

Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: bugfix Status: Open Resolution: None Priority: 5 Private: No Submitted By: Luke Iannini (lukeiannini) Assigned to: Miller Puckette (millerpuckette) Summary: update to [cnv] help to document arguments
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 patch does not apply cleanly to anything that I tried. Please submit the original pd help patch rather than the diff/patch file. diffs don't really work with .pd files.

It would be awesome then if you updated the help file and submitted that as a patch to the tracker. Then the rest of us can benefit from your explorations.
You can attach an updated help file to this tracker, then change it from a "Bug" to a "Patch".

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:
- read the help (won't help you with [cnv])
- 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)
