I have a Tkx app, and I'm using the DynamicHelp BWidget for canvas

work for items identified using a single tag. I cannot get it to work
for 'tag expressions'.
I'm trying this:
Tkx::DynamicHelp__add ( $canvas, -item=> 'this_tag && !that_tag', ...
Is there a different syntax for this situation?
Can't say why that wouldn't work. It boils down to an addtag/withtag
call on the canvas, which does support the logical expressions.
Ah, I see it now. It registers correctly, but then is too conservative
in the popup phase checking for the item. It actually seems quite
screwy in its implementation for canvas items. It looks like it would
work by registering each individually after you do a 'find_withtag'
using that expression. The same would be true if you used the
alternative Tkx::tooltip__tooltip (tooltip package). Since it seemed
like a silly limitation, I've fixed the latter package (v 1.4.4, but the
tkkit has an earlier version of course). BWidget's code is a lot
goofier and I would recommend tooltip instead.
