Re: [Vala] How to assign to construct-only property?

[Hodong Kim <cogniti gmail com>]

I have solved the problem.

My question have been derived from my ignorance of GObject.
Sorry my ignorance.

class MyClass : Object
{
    public bool construct_only_property { get; construct; default = false; }
    public void print_construct_only_property()
    { stdout.printf("%s\n", construct_only_property.to_string()); }
}


void main (string[] args)
{
    // set construct-only property
    var instance1 = (MyClass) GLib.Object.new (typeof(MyClass),
                                               construct_only_property:
true);

    instance1.print_construct_only_property(); // print true,  Correct,
Good.

    var instance2 = new MyClass();

    instance2.print_construct_only_property(); // print false, Correct,
Good.
}


---- gsf-decompress.vala ----

void main (string[] args)
{
    Gsf.InfileMSOle olefile;

    string filename = args[1];

    try   {
        var file = new Gsf.InputStdio (filename);
        olefile  = new Gsf.InfileMSOle (file);
    }
    catch {
        stderr.printf ("%s is not a OLE file\n", filename);
        return;
    }

    var input = olefile.child_by_name("DocInfo");

    Gsf.InputGZip stream;
    stream = (Gsf.InputGZip) GLib.Object.new (typeof(Gsf.InputGZip),
                                              raw:    true,
                                              source: input);
}

$ valac gsf-decompress.vala --pkg libgsf-1
