Re: Question about ToolTips

[A. Arias]

It works. But on fisicalab the buttons change its data according with
the problem the user is solving. So, the tooltips needs update its
content. Other point is that buttons are side by side (in touch). I
suppose that if I leave an space between buttons, this will solve the
problem. But I don't want do that. Regards.
