[glade--] Code generation of buttons

[André Offringa <offringa gmail com>]

Hello Glademm list,

I have an odd problem using glade-- to generate code... When I start a 
new project in Glade, add a new Window, then a new VBox and then a new 
Button in the VBox, the following code (part) is generated:

** part of generated window1_glade.cc: **
window1_glade::window1_glade(
)
{  window1 = this;
  gmm_data = new GlademmData(get_accel_group());
  button1 = Gtk::manage(new class Gtk::Button("button"));
  vbox1 = Gtk::manage(new class Gtk::VBox(false, 0));
  button1->set_flags(Gtk::CAN_FOCUS);
  window1->add(*vbox1);
  button1->show();
  vbox1->show();
}
** end part **

But... vbox1->pack_start(*button1) should have been somewhere. When 
compiling and running this code, the button is not visible. This is also 
the case when placing buttons in the other containers. However, when I 
add the button directly to the Window, the Button does get added:

** part of generated window1_glade.cc: **
window1_glade::window1_glade(
)
{  window1 = this;
  gmm_data = new GlademmData(get_accel_group());
  button1 = Gtk::manage(new class Gtk::Button("button"));
  button1->set_flags(Gtk::CAN_FOCUS);
  window1->add(*button1); // <---
  button1->show();
}
** end part **

Other components do get added to the VBox, such as labels. When I for 
example add a label and a button to the VBox, the following code is 
generated:

** part of generated window1_glade.cc: **
window1_glade::window1_glade(
)
{  window1 = this;
  gmm_data = new GlademmData(get_accel_group());
  label1 = Gtk::manage(new class Gtk::Label("label"));
  button1 = Gtk::manage(new class Gtk::Button("button"));
  vbox1 = Gtk::manage(new class Gtk::VBox(false, 0));
  button1->set_flags(Gtk::CAN_FOCUS);
  vbox1->pack_start(*label1); // <--
  window1->add(*vbox1);
  label1->show();
  button1->show();
  vbox1->show();
}
** end part **

So... Am I overlooking something terrible, or is this a bug?

Version info:
$ glade-- --version
glademm V2.6.0 (glade to Gtk-- converter)
$ glade-3 --version
glade3 3.4.3

(I'm using Debian Testing)

Kind regards,
