The document discusses Swing components, which are essential building blocks for GUI applications in Java. It details the types of top-level containers, such as JFrame, JDialog, and JApplet, and explains their roles in the component hierarchy. Additionally, it covers general purpose containers, basic controls, uneditable displays, and interactive formatted information displays.

- 2. * Swing components are basic building blocks of an application. * Swing has a wide range of various components, including buttons, check boxes, sliders, and list boxes. 1. What are Swing Components
- 3. 1. Top Level Containers * Every program with a Swing GUI must contain at least one top-level Swing container that provides the support that Swing components need to perform their painting and event handling. * Swing provides three generally useful top-level container classes: 1. JFrame 2. JDialog 3. JApplet. * Each JFrame object implements a single main window, and each JDialog implements a secondary window (a window that's dependent on another window). Each JApplet object implements an applet's display area within a browser window.
- 4. When using these classes, you should keep these facts in mind: • To appear onscreen, every GUI component must be part of a containment hierarchy. Each containment hierarchy has a top-level container as its root. • Each top-level container has a content pane that, generally speaking, contains the visible components in that top-level container's GUI. • You can optionally add a menu bar to a top-level container. The menu bar is positioned within the top-level container, but outside the content pane.
- 5. Here's a picture of a frame created by an application. The frame contains a green menu bar (with no menus) and, in the frame's content pane, a large blank, yellow label.

- 8. 1. Typically used to collect Basic Controls (JButton, JChoiceBox…) 2. Added to layout of top-level containers JPanel JFrame
