Description Sebastian Dröge (slomo) 2010-04-07 09:07:50 UTC 
Code like this should work in the future (also with simple generics):


using GLib;

delegate void Foo<G> (G x);

private void foo<G> (G x) {
  string? xx = (string?) x;
  stdout.printf ("%s\n", xx.to_string ());
}

static int main(string[] args) {
    Foo<string?> f = foo<string?>;
    f ("123");
    
    return 0;
}
Comment 1 Sebastian Dröge (slomo) 2010-04-08 09:16:12 UTC 
Assignments between variables of type delegate void A<T>(T x) and delegate void B (string x) should also be possible if T==string, same if B is a method of that type.
