• This topic looked at the design and implementation of Graphical User Interfaces (GUI).
• The behaviour of a GUI is determined by its current state and by the events, like a mouse click, that can occur. The states, events, and response actions can be modelled as a Finite State Machine (FSM) to describe the dynamic behaviour of the GUI.
• Events can be handled according to different event models which need to be understood by the designer.
