[NTG-context] Tooltips

[NTG-context] Tooltips

[Giuseppe Bilotta]

Hello,

I notice that the "active area" that triggers tooltips is a little
misplaced to the bottom right. Is this a "wanted" effect?

Sorry, i can not answer this, but your question reminded me that
i have also an question about tooltips:

Is it possible to make the whole word an active area for the tooltip
instead of the currently used small area below?

Thanks,
  Jens

yes, has to do with convenient pointing area -)

That's precisely what I want, too. Hans? Still "has to do with
convenient pointing area"? It's not very convenient the way it is
now, really ... :D

I agree!

And as I tried it last time, the tooltip text was ugly stretched in width.
Don't know if this is possibly fixed in the actual edition.

i was thinking that the framedclass= option could mean that the object
inherits the configuration of the framed-class. So

\defineframed[MyFramed][frame=off,leftframe=on,topframe=on,framecolor=red]

can be used as \MyFramed, but even in

\balloon[framedclass=MyFramed,framecolor=green]{...}{...}

This balloon would have the top-frame and the left-frame visible,
but the frame is drawn in green instead of red. Thus you _can_ specify
a framedclass= to inherit a configuration but you have also all
other framed-parameters (see \setupframed) available.

For consistency this should be possible in all objects that support
framed-settings, not only in balloons.

I have a draft implementation for this.

By now, the only thing
that can be configured is the framecommand. I decided to use this
instead of a frameclass because it's even more flexible
(with frameclass, you need to define a different frame class for each
different ballon type, even if changes are small; this way, small
changes can be applied more easily when defining new tooltips.)

Put the following code in your cont-new.tex file or in your
cont-loc.tex file (whichever you use for customizations), until
Hnas decides to pass it to the core. I hope to come out myself
with more customization options, but I would have to study fields
and co. Maybe I'll leave that to Hans though.

BTW, your stuff seems to more oriented towards what Hans called
"helps" rather than tooltips, but I don't know much about this
feature.

Anyway, here's the code for custom balloons. Hope I didn't
reinvent the wheel ...
