They are defined in the superclasses Component, Container, and JComponent. So far in this chapter you have used several GUI components (e.g., JFrame, Container, JPanel, JButton, JLabel, and JTextField). Many more GUI components will be introduced in this book. It is important to understand the common features of Swing GUI components. The Component class is the root for all GUI components and containers. All Swing GUI components (except JFrame, JApplet, and JDialog) are subclasses of JComponent, as shown in Figure 12.1. Figure 12.11 lists some frequently used methods in Component, Container, and JComponent for manipulating properties such as font, color, mouse cursor, size, tool tip text, and border. A tool tip is text displayed on a component when you move the mouse onto the component. It is often used to describe the function of a component. java.awt.Component -font: java.awt.Font -background: java.awt.Color -foreground: java.awt.Color -preferredSize: java.awt.Dimension -visible: boolean -cursor: java.awt.Cursor +getWidth(): int +getHeight(): int +getX(): int +getY(): int The get and set methods for these data fields are provided in the class, but omitted in the UML diagram for brevity. The font of this component. The background color of this component. The foreground color of this component. The preferred size of this component. Indicates whether this component is visible. The mouse cursor shape. Returns the width of this component. Returns the height of this component. getX() and getY() return the coordinate of the component’s upper-left corner within its parent component. java.awt.Container +add(comp: Component): Component +add(comp: Component, index: int): Component +remove(comp: Component): void +getLayout(): LayoutManager +setLayout(l: LayoutManager): void Adds a component to the container. Adds a component to the container with the specified index. Removes the component from the container. Returns the layout manager for this container. Sets the layout manager for this container. -toolTipText: String javax.swing.JComponent -border: javax.swing.border.Border The get and set methods for these data fields are provided in the class, but omitted in the UML diagram for brevity. The tool tip text for this component. Tool tip text is displayed when the mouse points on the component without clicking. The border for this component. FIGURE 12.11 JComponent.
