On de.wikibooks, there were a lot of launched books arround GTK+,
but most of them died just before the first chapters are written. I
wanted to sell the book, but no german publisher was interested in
the idea. They told me, that there is no market for books about
GTK+, so I decided to put everything I had to de.wikibooks. I hope,
it is good enough for a public book. Some, but very few guys have
contributed and I hope, more will do so.

Sorry, I'm not.

* You need to call g_object_set_property() or similar with the
property "has-tooltip". In this case only, your callback gets executed.

* if you insert a button into your liststore.c file, your callback can call
g_object_set_property( treeview, "has-tooltip", a_gvalue ) and this a_gvalue
can change each time you hit the button.
With this, you can toggle the tooltips.

I don't know, if this is best practice. There may be some better solutions.

Best regards
