Re: [Vala] Defining new virtual signal is possible, but overring it isn't.

[Derek Dai <daiderek gmail com>]

You can try code below as solution/workaround.

class Foo : GLib.Object
{
public virtual signal void func()
 {
message("Foo");
}
}

class Bar : Foo
{
public override void func()
{
 message("Bar");
}
}

int main()
{
Foo foo = new Bar();
foo.func.connect(() => { message("Main"); });
 foo.func();
 return 0;
}
