Solution
Use HTML in the text of the component.
Discussion
The Swing components that display text, such as
JLabel
, format the text as HTML—instead
of as plain text—if the first six characters are the obvious tag
<html>
. The program
JLa-
belHTMLDemo
just puts up a
JLabel
formatted using this Java code:
public
public class
class
JLabelHTMLDemo
JLabelHTMLDemo
extends
extends
JFrame
{
/** Construct the object including its GUI */
public
public
JLabelHTMLDemo
() {
super
super
(
"JLabelHTMLDemo"
);
Container cp
=
getContentPane
();
JButton component
=
new
new
JButton
(
"<html>"

"<body bgcolor='white'>"

"<h1><font color='red'>Welcome</font></h1>"
+
"<p>This button will be formatted according to the usual "
+
"HTML rules for formatting of paragraphs.</p>"
+
"</body></html>"
);
