Re: GObject Destruction

[Günther Wutz <android gunibert de>]

I can live with that. I thought it should be possible, because its a
normal thing in an object oriented fashion. I looked at the generated
output from Vala, but they does not use multidimensional arrays, they
make the calculation themself and use a one-dimensional array. Then
freeing is simple :)

It works, if i use g_object_get(...), its only throws critical messages.
The problem is a refcount-check. If i make myself an cast to the correct
structure and use the variables would maybe work but its only a
workaround.
