Java Swing

Conventions

The following font conventions are followed throughout this book:

Italic

is used for filenames, file extensions, URLs, application names, and emphasis.

Constant width

is used for Java class names, functions, variables, components, properties, data types, events, and snippets of code that appear in text.

We use tables throughout the book to present lists of properties (as defined by the JavaBeans specification). Here’s an example from the hypothetical JFoo class that shows how we use these tables:

Table 1. Properties of the Fictional JFoo Class

Property	Data Type	get	is	set	bound	Default Value
See also properties from the JComponent class (Table 3.5).
	opaque*	boolean	•	•	•	•	true

This table indicates that a JFoo object has a read/write bound property named opaque, with the data type boolean. This property has accessor methods with the signatures:

public boolean getOpaque();
public boolean isOpaque();
public void setOpaque( boolean opaque );

These methods aren’t listed separately when we discuss the class’s other methods. Because this is a bound property, changing its value generates a PropertyChangeEvent. JFoo has also inherited properties from the JComponent class; see the discussion of that class for these properties. The asterisk after the property name indicates that the opaque property is also inherited; it is listed here because the JFoo class has changed the behavior of the property in some way—either by adding accessor methods ...
