Hey Jonathan,

I'm cc'ing pd-dev since this is a topic that could interest others and others could contribute to.  I've started a private git branch of tkwidgets that I intent to push once I get somewhere with it.  The idea is to try out a new idea for how GUI objects can work.  Basically, I think I can make it so that Tcl handles more of the interaction with the user, minimizing on pd-gui <--> pd communications, and making it easier to write GUI objects.  Its not trivial to do, but should be doable.

Never mind, I see it now inside canvas_vis... too bad canvas' "window" subcommand doesn't have something like pack's "-in" option...

But I guess I could make a toplevel checkbutton widget and just manually clone it.

Hi Hans,
     Do I have it right that your tkwidgets get destroyed when the containing patch is vis'd 0?  If so, any hints on how this happens?

Specifically, I'm playing around with [checkbutton], and even if I comment out everything in eraseme and checkbutton_free, and every single "destroy" subcommand, I still get a tcl error when sending a bang or float to a [checkbutton] that's in a subpatch with no window mapped:

(Tcl) INVALID COMMAND NAME: invalid command name ".x252a690.c.widget25272b0"
    while executing
".x252a690.c.widget25272b0 cget -onvalue"
    ("uplevel" body line 2)
    invoked from within
"uplevel #0 $cmd_from_pd"
