Are there a bz entry for libgee? I wasn't able to find it.
When the collections in Gee are holding strong references, it is
difficult to obtain a weak reference to the elements in the container.
The situation is:
class Node {
Gee.List<Node> childNodes;
public Node? firstChild {
get {
return childNodes.get(0);
////// panic! the signature of properties are weak!.
}
}
}
I was able to workaround by
get {
Node rt = childNodes.get(0);
return rt;
}
But this doesn't look intuitive and causes further troubles[difficult to
explain]. a better looking solution is
get {
return childNode.get_weak_ref(0);
}
The attached patch adds get_weak_ref to libgee.
