Oops-- I didn't think about that. That's one of the few remaining differences between the internals of Vanilla and Extended, right?
a diff file would be a great thing :D
Yes, that's the next thing I'm going to learn...
I couldn't water parchy, maybe because I'm missing [expr] object?
Which Pd are you using that's missing [expr]?
expr $f1>68 && $f1<79 ... couldn't create expr $f1>457 && $f1<462 ... couldn't create args

Oh, and... I'm not sure if screenpos is totally
accurate. I haven't
tested it in different window managers.

From: Jonathan Wilkes jancsika@yahoo.com Subject: canvas get method To: Pd-dev@iem.at Date: Tuesday, May 24, 2011, 6:30 PM Hi list, Here's my first attempt at some c code to create a "get" method to query the properties of a canvas. I included
the
entire g_canvas.c from 0.43 (haven't started using git and diff yet) and
a demo
patch with some helper abstractions. Some things that it does:
- [namecanvas] (and [sendcanvas]) are _actually_
obsolete
- canvas environment variables available to the
user
(filename, dir, canvas-local paths, dollarzero)
- parent attributes (like dollarzero) are
gettable without
having to give it as an argument to the abstraction
- possible to find the toplevel canvas that
contains "this"
abstraction (plus making all kinds of
"canvas-abs" like the
list-abs lib)
- ability to get gop status, coords values, patch
screen
position, abstraction's position on parent, and other
goodies that
are currently scattered all around external libraries with
various
interfaces
- abstraction can get a list of all attributes
(like
dollarzero) from all the abstraction instances that exist.
(Probably
should institute patch 1403917 to make this rock-solid.)
- parent args are gettable!
Things seem to work alright so far, but I'm not
sure how to
handle reentrancy. Also, I'm currently replying to
queries
using the attribute as a selector. The only model I had-- the
[cnv]
get_pos-- just sends the data, but it seems cleaner to send to one
receive-symbol
and [route] accordingly. (I also much prefer one "get"
method to
separate ones to access each attribute.)
