Re: [Vala] screen-changed signal emitted before constructor is invoked?

[Arto Karppinen <arto karppinen mail suomi net>]

You should probably init you private member variable like this:

public class test : Object {

        // Set it here.
        public some_class var = new some_class();
        
        test()
        {
                ....
        }
}
