You probably want to look for the FL_ENTER and FL_LEAVE events.
You'd have to derive a class, eg. "MyGroup" from the Fl_Group.

If you derive a group, just set the Class: for the actual
widget in your layout (in fluid's properties) to the name
of your derived group, eg. MyGroup. See example below.

Can't avoid that, I don't think.

Here's an example of how to watch mouse movement
without clicks. (I used this for reference for the below):

Using that as an example, I made the following entirely within fluid;
should do exactly what you describe.
