[Bug 69806] Re: Gtk::Adjustment ignores initial value in constructor

[Daniel Holbach]

Thanks for your bug report. This looks valid. Murray, do you want me to
forward it upstream?


On a brief glance:

Code in gtkmm 2.8.5:
Adjustment::Adjustment(double value,
                       double lower, double upper,
                       double step_increment, double page_increment,
                       double page_size)
:
  Glib::ObjectBase(0), //Mark this class as gtkmmproc-generated, rather than a custom class, to allow vfunc optimisations.
  Gtk::Object(Glib::ConstructParams(adjustment_class_.init(), (char*) 0))
{
  gobj()->lower = lower;
  gobj()->upper = upper;
  gobj()->step_increment = step_increment;
  gobj()->page_increment = page_increment;
  gobj()->page_size = page_size;
  changed();

  set_value(value);
}

void Adjustment::set_value(double value)
{
    gtk_adjustment_set_value(gobj(), value);

}


(For some reason set_value() doesn't use
  gobj()->value = value;
  changed();
as the other set_*() do. But maybe that's a red herring.)

Code in gtkmm 2.10.2:
Adjustment::Adjustment(double value, double lower, double upper, double step_increment, double page_increment, double page_si
ze)
:
  Glib::ObjectBase(0), //Mark this class as gtkmmproc-generated, rather than a custom class, to allow vfunc optimisations.
  Gtk::Object(Glib::ConstructParams(adjustment_class_.init(), "value", value, "lower", lower, "upper", upper, "step_increment
", step_increment, "page_increment", page_increment, "page_size", page_size, (char*) 0))
{
  }
