Hi,

I've solved the issue! :-) :-) :-)

Below I'm telling you what's going wrong.

This happened because a frame laid BEHIND the widgets. After put the
widgets IN the frame (or better in a fixed container in the frame)
the tooltips working as expected.

It was very interesting to put the frame above the widgets - no widgets
are shown but the tooltips appearing fine without a targeted search
which gives me the hint that now the events for showing a tooltip are
generated in the areas not at the borders like before.

This brought me to the idea to put the widgets in a fixed container in
a frame <= works perfect. ;-)

This behaviour resulted in the fact that I created gtk main in the
script and not in the class.

And this implementation I am using now.

This issue was fixed with the two changes above ^^

This worked but I run in the issue that I can't get from all widgets
the real size information. Ok, now I know it but I'm using Gtk2::Tooltip
and this solution is outdated now :-P

With a modified fixed example from the old Gtk1 tutorial I was able to 
confirm that Gtk2::Tooltip works fine in a fixed container.

So, story finished. ^^

Best,
Thomas
