//: Abstract base class for horizontal and vertical boxes
//- {Gtk::Box::} is an abstract class and it defers choice of which
//- way the widgets are packed to the screen to the derived classes.
//- {Gtk::Box::} provides common interface for inserting widgets
//- to a box indepenently of how it is shown in the screen.
//-
//- The most common use of {Gtk::Box::} is like this:
//- {\example
//-
//- class mywindow : public Gtk_Window {
//-    Gtk_Label label1,label2;
//-    Gtk_VBox vbox;
//- public:
//-    mywindow();
//- };
//- mywindow::mywindow()
//- {
//-    add(vbox);
//-    vbox.pack_end(label1, true, true, 0);
//-    vbox.pack_end(label2, true, true, 0);
//- }
