Hi folks.
I have struct from external C library, I wrote vapi:
[CCode ...]
public struct sameitem{
....
}
[CCode (cheader_filename = "makeflop.h")]
public struct listinfo {
...
[CCode (array_length_cname = "num", array_length_type = "int")]
public weak sameitem[] list;
...
}
I create GTK3 ListStore model with pointer data:
new ListStore(8, typeof(void*) ....)
And fill model:
(I have listinfo)
listinfo info;
foreach(listinfo i in info.list){
ii_list.append (out iter);
ii_list.set(iter, 0, &i)
}
But pointer on "&i" is not pointer to info.list[iterator].
Vala create object "listinfo i" and copy struct in to it:
for(..){
listinfo i=info.list[iteration];
ii_list.append (out iter);
ii_list.set(iter, 0, &i)
}
Result: I have array bad pointers. Pointers to local listinfo items.
How I can make array to info.list[iterators] if I want use "foreach"?
Example, I write valid code using "for":
for(j=0; j<info.list.length; j++){
ii_list.append (out iter);
ii_list.set(iter, 0, &l.ii[j] /<cut>)
}

Sorry for my english
