MGS [2004/02/09] - I'm hoping to have some time soon to add a '-command' option. You might like to read the original announcement thread at: [1].

LV tklib now has a tooltip package, which provides tooltip management. Hopefully someone will add info or a pointer to info here.

http://tcllib.sourceforge.net/doc/tooltip.html is the doc for the tklib's tooltip package. Here's an example:

package require tooltip
pack [label .l -text "label text"]
tooltip::tooltip .l "This is a label widget.\nThis is a second line.\nThis is the third line of comments."

Run the above on a machine with tklib installed, then move your mouse cursor over the label widget.
