Not sure if that's what you mean, but in max the
assist method receives a number corresponding to the inlet
or outlet and returns a pointer to the appropriate string,
so the string is already stored somewhere in the memory
allocated to the object.
Not necessarily : the assist-method could be storing the
data anywhere, or generating it on-the-fly from whatever.
Hm...
1 when creating an xlet for the first time, bind its tag on <Enter>
and <Leave> to call pdtk_tooltips, and send $canvas, $inletno and
$object_name as arguments
2 in tcl, search helppath for $object_name-help.pd, then parse it
for $inletno (which I added as a pd META tag for every internal help
patch-- plus lots of externals, too)
3 filter the matching line in tcl to display everything after
$inletno minus the semicolon. (I.e., "text 20 20 INLET_0 float
symbol bang;" becomes "float symbol bang")
4 create that text on a little tooltip rectangle on $canvas; delete
it on <Leave>
All you add on the pd side is a sys_gui call to create the binding,
then handle everything else on the tcl side.
Does that make sense? If so, then once someone gets it working
(maybe me), you'd not only have tooltips, but you'd have tooltip
content for over 1000 object classes (minus exceptions like "list
split", and variable/rightmost inlets which I'm not sure how to
handle...)
Also doesn't address tooltips for abstractions.

I like this idea quite a bit. If the tooltip info is stored in a help
patch, then we have a single way of specifying the tooltip info
regardless if the object was written in C, Pd, Lua, etc. The downside
will be a lot more file parsing on load. Perhaps we can do some kind
of low priority thread kind of thing in Tcl to do that loading.
One detail, instead of searching the path for the help patch, really
we should try to get the full path of the object in question, then use
that to get the help patch...
