add

Adds widget to this.

Typically used for simple containers such as Window, Frame, or Button; for more complicated layout containers such as Box or Grid, this function will pick default packing parameters that may not be correct. So consider functions such as pack_start and 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 ListBox, may add intermediate children between the added widget and the container.
