1. Graphical User Interfacejava objects that are provided for the GUI exist in Java. AWT and javax. Swing two packages in Java. Awt:abstract window Toolkit Abstract Windows Toolkit needs to invoke Local System method implementation functions, poor portability, dependent system. Heavy-weight control javax. Swing's set of graphical interface systems, based on AWT, provides more components that are fully implemented by Java. Good portability, lightweight control eclipse is an SWT-developed Component: Component container: Container panel: faceplate Frame: Frame Dialog: Dialog checkbox checkbox: check box 2. The Layout Manager container's components are emitted by the layout. Common layout Manager: FlowLayout Flow layout: Left-to-right order, panel default layout manager borderlayout Boundary Layout manager: East, frame default layout manager GridLayout Grid layout Manager : Rule grid cardlayout card layout Manager: Tab gridbaglayout Grid package Layout Manager: Irregular grid 3. Basic steps to create a graphical interface: 1. Create a Form 2. Basic setup of the Form 3. Define component 4. Add the component to the form 5. Set the Visualize 4. Event Monitoring mechanism features: 1. Event Source: The graphical interface component in the AWT package or swing package 2. Events: Each event source has its own unique corresponding event and commonality event 3. Listener: Actions that can trigger an event are already encapsulated in the listener--- The above 3 are defined in Java 4. Event handling:
