private static void buildGui() {
JFrame frame = new JFrame();
JTextArea textArea = new JTextArea(5, 20);
// set default font size to 10 to match JSlider starting position
textArea.setFont(new Font(textArea.getFont().getName(), textArea.getFont().getStyle(), 10));
frame.add(textArea, BorderLayout.CENTER);
// set up slider
JSlider slider = new JSlider(JSlider.HORIZONTAL, 10, 30, 10);
slider.setMajorTickSpacing(5);
slider.setMinorTickSpacing(1);
slider.setPaintTicks(true);
slider.setPaintLabels(true);
frame.add(slider, BorderLayout.SOUTH);
// create and add change listener
slider.addChangeListener(new ChangeListener() {
@Override
public void stateChanged(ChangeEvent e) {
int fontSize = slider.getValue();
Font currentFont = textArea.getFont();
// get the current font and set the modified font size
textArea.setFont(new Font(currentFont.getName(), currentFont.getStyle(), fontSize));
}
});
frame.pack();
frame.setVisible(true);
}
