public virtual signal void add (Widget widget)
Adds widget to this.
Typically used for simple containers such as Window,
Frame, or Button; for more complicated layout containers such as
Box or GtkGrid, this function will pick default packing parameters that may not be
correct. So consider functions such as pack_start and gtk_grid_attach as
an alternative to add in those cases. A widget may be added to only one container at a time; you can’t
place the same widget inside two different containers.
Note that some containers, such as ScrolledWindow or GtkListBox, may add
intermediate children between the added widget and the container.
