GtkExpanderA container that can hide its child.
Hierarquia de Objetos
GtkExpander creates a container that can hide or display details on request. This is achieved by using a small triangle (similar to the one used in GtkTreeView) to control whether the details are shown or not. If the triangle is pointing to the right, details are hidden. On clicking the object, the triangle points downward which indicates that the details are now visible.
You can use GtkExpander as any other descendant of GtkBin by first creating the child widget and then using add() to add it to the expander. When the expander is toggled, it automatically takes care of showing and hiding the details.
