Changing the font in a text field/text area

---

• Selecting/changing display fonts
  • A text field or text area can use different fonts to display the text

    ---

  • Properties of a font:

    font name Examples: Roman SansSerif (no "curves" -- block-like characters) Monospaced (every character has the same width) font size Examples: 10 (kinda small...) 12 (this size is pretty readable) 16 (big letters) font face Examples: BOLD ITALIC PLAIN

    ---

  • Selecting a display font for a text area (also works for JLabel, JButton, JTextField and JTextArea):

    JTextArea x = new JTextArea(); Font f = new Font( "FontName", Font.FontFace, size ); x.setFont( f );

    Example:

    JTextArea x = new JTextArea(); Font f = new Font( "Roman", Font.ITALIC, 12 ); x.setFont( f );

    New text in the text area will now be displayed in Italic 12 points Roman font.

  • Example Font Selection:

    import java.awt.*; import javax.swing.*; public class SelectFont { public static void main(String[] args) { JFrame f = new JFrame("My GUI"); JTextArea x; JScrollPane y; Font F; x = new JTextArea(); // Make a JTextArea x.setEditable(true); // Output only y = new JScrollPane(x, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS); f.getContentPane().add(y); // Stick F = new Font("Monospaced", Font.BOLD, 18); x.setFont( F ); x.setText("Hello World"); x.append("\n\n\n"); x.append("Hello Again"); f.setSize(400, 300); f.setVisible(true); } }
