JAVA JToolTip

This example uses UIManager setting tooltip's forground and background color. It assigns tooltip to a Jbutton.

public class ColoredToolTipExample extends JFrame {
public ColoredToolTipExample() {
super("Colored ToolTip Example");

UIManager.put("ToolTip.foreground",
new ColorUIResource(Color.red));
UIManager.put("ToolTip.background",
new ColorUIResource(Color.yellow));

JButton button = new JButton ("Hello, world");
button.setToolTipText("Red / Yellow");
getContentPane().add(button);
}

public static void main (String args[]) {
ColoredToolTipExample f = new ColoredToolTipExample();
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
f.setSize (300, 100);
f.show();
}
}
