As the title suggests, I am attempting to add an action listener to a basic shape on a window. I'm wondering if this is even possible? I'm getting errors when I attempt to add the listener.
public static void main(String args[]) {
JFrame frame = new Main();
frame.setSize(300, 200);
frame.setVisible(true);
frame.setBackground(Color.BLUE);
}
Rectangle2D rect = new Rectangle2D.Double(60, 70, 120, 80);
public void paint(Graphics g) {
Graphics2D g1 = (Graphics2D)g;
g开发者_JAVA技巧1.draw(rect);
g1.setPaint(Color.yellow);
g1.fill(rect);
}
Handlerclass handle = new Handlerclass();
rect.addMouseListener(handle);
public class Handlerclass implements MouseListener{
public void mouseClicked (MouseEvent e){
}
}
You can't add a mouse listener to that object. If you are trying to detect mouse clicks within it then you want to add a mouse listener to whatever Swing container you are drawing the shape in, then use one of the contains...
or intersects...
methods.
Check out the documentation for Rectangle2D when you get a chance.
