Java: does mouseMoved event and button .addMouseListener fire?
Now I am using the following code to draw the cursor (with a large size):
Cursor emptyCursor = Toolkit.getDefaultToolkit().createCustomCursor(new BufferedImage(12, 12, BufferedImage.TYPE_INT_ARGB), new Point(0, 0), "empty");
setCursor(emptyCursor);
Toolkit toolkit = Toolkit.getDefaultToolkit();
final long eventMask = AWTEvent.MOUSE_MOTION_EVENT_MASK + AWTEvent.MOUSE_EVENT_MASK + AWTEvent.KEY_EVENT_MASK;
final ImageIcon icon = createImageIcon("images/cursor.png");
cursorLabel = new JLabel(icon);
toolkit.addAWTEventListener(new AWTEventListener() {
public void eventDispatched(AWTEvent e) {
MouseEvent me=(MouseEvent)e;
cursorLabel.setLocation(me.getLocationOnScreen().x, me.getLocationOnScreen().y);
}
}, eventMask);
layeredPane = this.getLayeredPane();
if (icon != null) {
cursorLabel.setBounds(15, 225, icon.getIconWidth(), icon.getIconHeight());
} else {
System.err.println("Cursor Icon not found!");
}
layeredPane.add(cursorLabel);
Then I used the following code for the button:
button.addMouseListener(new MouseListener(){
public void mouseClicked(MouseEvent arg0) {
}
public void mouseEntered(MouseEvent arg0) {
button.setBackground(Color.yellow);
}
public void mouseExited(MouseEvent arg0) {
button.setBackground(Color.white);
}
public void mousePressed(MouseEvent arg0) {
}
public void mouseReleased(MouseEvent arg0) {
}
});
The cursor works fine, but only if I don't press the button, because it's drawn under the button. What's the problem?

Buttons have their own MouseListener to handle rollover effects. This way, the MouseEvent is only passed to the button, not the layered panel.
Perhaps you can use AWTEventListener to listen for mouse events. See Global Event Listeners for details .
