As we saw in Drawing Text , you can manually select a font by calling the java.awt.Font
class constructor, passing in the name of the font, the type you want (plain, bold, italic, or
bold+italic), and the point size:

Font f = new Font("Helvetica", Font.BOLD, 14);
setfont(f);

This is not very flexible for interactive applications. You normally want the user to be able to
choose fonts with the same ease as using a File Chooser dialog. Until the Java API catches
up with this, you are more than welcome to use the Font Chooser that I wrote when faced
with a similar need.

The source code is shown in Example 14-12 ; it ends, as many of my classes do, with a short
main method that is both a test case and an example of using the class in action. The display
is shown in Figure 14-17 .

Example 14-12. FontChooser.java
// package com.darwinsys.swingui;
public

public class class FontChooser FontChooser extends extends JDialog {

private private static static final final long long serialVersionUID = 5363471384675038069L ;

public public static static final final String DEFAULT_TEXT = "Lorem ipsem dolor" ;

// Results:

/** The font the user has chosen */
protected

protected Font resultFont = new new Font ( "Serif" , Font . PLAIN , 12 );

/** The resulting font name */
protected protected String resultName ;

/** The resulting font size */
protected protected int int resultSize ;

/** The resulting boldness */
protected

protected boolean boolean isBold ;

/** The resulting italicness */
protected protected boolean boolean isItalic ;

// Working fields

/** Display text */
protected protected String displayText = DEFAULT_TEXT ;
