Study Notes
AWT Controls and Components
- A label is a passive AWT control that does not generate any event.
- The ActionEvent class is used primarily with List, Button, and Checkbox controls.
- CardLayout arranges components like a deck of cards, showing only one component at a time.
Platform Dependency
- AWT components are platform dependent, which means their appearance and behavior can vary across different operating systems.
Understanding Events
- A change in the state of an object is referred to as an event.
- Event listeners are typically implemented as interfaces in Java.
AWT Component Functions
- The Scrollbar component allows users to select a value from a specified range.
- The Frame class is used to create a window with a title bar, borders, and buttons.
Layout Management
- FlowLayout is a layout manager that automatically resizes components to fill the available space.
- The Model-View-Controller (MVC) architecture consists of the Model, View, and Controller components.
Frame Creation and Action Command
- Creating a Frame can be done through inheritance or association with the Frame class.
- The getActionCommand() method retrieves the label text or identifier associated with an action event.
