#60 Changing Fonts Throughout Your Application

HACK

Fonts ’R’ Us

To run the code, you specify the name of your desired font on the com-

mand line as the only argument to the class. If the font you want to use has

one or more spaces in its name, you’ll need to enclose the font name in

quotes, as in the example:

cadamson% java ChangeAllFonts "Comic Sans MS"

This produces a GUI whose components all use the 12-point plain Comic

Sans MS font, as seen in Figure 8-5.

You should also note the standard output when running this example, since

the code prints out every

.font key it finds. The output is too long to list

here, but the first few items look like this:

JFrame frame = new JFrame ("Changing default fonts");

frame.setDefaultCloseOperation (WindowConstants.EXIT_ON_CLOSE);

frame.getContentPane( ).add(panel);

frame.pack( );

frame.setVisible(true);

} catch (Exception e) {

e.printStackTrace( );

}

}

}
