Study Notes
Abstract Windowing Toolkit (AWT)
- AWT provides various controls, including labels, push buttons, checkboxes, choices, lists, scroll bars, text areas, and text fields.
- Menu bars in AWT can be implemented using MenuBar, Menu, and MenuItem classes.
- The TextEvent class constructor is defined as
TextEvent(Object source, int event_type). - An event in Java is an object specifying the change of state in the source.
- Classes and interfaces in AWT are located within the
java.awt.*package. - The general form to set a specific type of layout manager is
void setLayout(LayoutManager lm). - AWT containers are instances of the Container class, which holds various components and other containers.
- A checkbox consists of a combination of a small box and a label, enabling binary selections.
- Java applets are primarily used for creating graphical and user-interactive applications.
- AWT stands for Abstract Window Toolkit.
- An event is generated when the internal state of the event source is changed.
- The BorderLayout positions components into five regions: east, west, north, south, and center.
- CardLayout arranges components like a deck of cards, showing only one at a time.
- FlowLayout arranges components horizontally.
- GridLayout arranges components into a grid format.
- The Choice control creates a dropdown list of textual entries.
- The Component class is abstract, with subclasses being used to create actual components.
- AWT classes are categorized into GUI Components, Layouts, Graphics Tools, and Event Handlers.
- An Applet is a subclass of the Panel class.
- Subclasses of Window include Dialog and Frame.
- A menu bar displays a list of menus at the top of a top-level window.
- Each menu is associated with a drop-down list of menu items.
- Two types of menus in AWT are pop-up menus and regular menus.

- Text field creates a single-line text area, while text area creates a multi-line text area.
- A push button is an active control that typically has a three-dimensional appearance.
- TextComponent is the superclass of TextField and TextArea classes, enabling single-line or multiline text inputs.
- A label is used to display non-editable text on the window.
