POMy (Java/Swing) MouseListener isn't listening, help me figure out why
text
Body
copied!<p>So I've got a <code>JPanel</code> implementing <code>MouseListener</code> and <code>MouseMotionListener</code>:</p> <pre><code>import javax.swing.*; import java.awt.*; import java.awt.event.*; public class DisplayArea extends JPanel implements MouseListener, MouseMotionListener { public DisplayArea(Rectangle bounds, Display display) { setLayout(null); setBounds(bounds); setOpaque(false); setPreferredSize(new Dimension(bounds.width, bounds.height)); this.display = display; } public void paintComponent(Graphics g) { Graphics2D g2 = (Graphics2D)g; if (display.getControlPanel().Antialiasing()) { g2.addRenderingHints(new RenderingHints(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON)); } g2.setColor(Color.white); g2.fillRect(0, 0, getWidth(), getHeight()); } public void mousePressed(MouseEvent event) { System.out.println("mousePressed()"); mx1 = event.getX(); my1 = event.getY(); } public void mouseReleased(MouseEvent event) { System.out.println("mouseReleased()"); mx2 = event.getX(); my2 = event.getY(); int mode = display.getControlPanel().Mode(); switch (mode) { case ControlPanel.LINE: System.out.println("Line from " + mx1 + ", " + my1 + " to " + mx2 + ", " + my2 + "."); } } public void mouseEntered(MouseEvent event) { System.out.println("mouseEntered()"); } public void mouseExited(MouseEvent event) { System.out.println("mouseExited()"); } public void mouseClicked(MouseEvent event) { System.out.println("mouseClicked()"); } public void mouseMoved(MouseEvent event) { System.out.println("mouseMoved()"); } public void mouseDragged(MouseEvent event) { System.out.println("mouseDragged()"); } private Display display = null; private int mx1 = -1; private int my1 = -1; private int mx2 = -1; private int my2 = -1; } </code></pre> <p>The trouble is, none of these mouse functions are ever called. <code>DisplayArea</code> is created like this:</p> <pre><code>da = new DisplayArea(new Rectangle(CONTROL_WIDTH, 0, DISPLAY_WIDTH, DISPLAY_HEIGHT), this); </code></pre> <p>I am not really a Java programmer (this is part of an assignment), but I can't see anything glaringly obvious. Can someone smarter than I see anything?</p>
