Um GtkButton
deriva de um GtkContainer
, portanto ele pode conter qualquer outro widget. Basta usar o método add()
para adicionar um widget GtkBox
para o layout e os rótulos e um ícone dentro dele.
Aqui está uma recriação muito rápida no Glade, se você não conseguir descobrir com código Python puro, eu darei um exemplo quando tiver mais tempo.
