You might consider using a notebook widget instead. It does more or
less this, but looks prettier.

This should work fine. I think there must be a problem somewhere else
in your code. Maybe you are allocating "struct s1 handle" as a local
variable and it's goinig out of scope?

You should have handle as a local of main() (so it's always in scope
while your program runs), or allocate on the heap with g_new().
