Object Oriented Programming and Graphical Applications

Object Oriented Programming and Graphical Applications

1. Object Oriented Programming

   • Key Features
     • Classes
       • Classes define the characteristics of an object
       • Classes can be reused countless times
       • Classes allow for data encapsulation
       • Classes allow for polymorphism
       • Modularity
     • Objects
       • Objects are instantiated from classes
       • Multiple objects can be instantiated from a single clas

2. Graphical Applications

   • Key Features
     • Graphical Elements
       • Graphical programs often consist of a large number of graphical elements
         • Proposes a need for resuability within code
       • Buttons, text labels, text boxes, Menus (contextual etc.)
     • Interaction
       • Graphical applications often offer user interaction
         • Code needs to be structured, manageable, and efficient
       • Events
         • Mouse click, key down, key up, etc

3. Object Oriented Programming & Graphical Applications

   • Classes
     • Classes can be used to define graphic elements such as buttons etc.
       • Multiple buttons can be instantiated from the single class
     • Inheritance allows for the creation of different types of buttons derived from a super class
     • Encapsulation allows for the isolation of different interaction events.
     • Polymorphism allows for different outputs depending on parameters passed
       • Highly increases reusability
