Help with a Paint package I am writing please!!

Question

Hi, I am writing a program to work as a paint application. I have all the necessary buttons. One of my buttons needs to be able to add a small image to the painting frame by clicking the mouse onto the screen...for example, to display a picture of a house, I click the house button which then puts my house picture onto the scribble panel wherever I click the mouse. My problem is that I am new to java and I am stuck on how I can do this. I have put all the code on here which I have. If any one knows the code which I can add to make this work I would very much appreciate it as it is driving me insane!
Many thanks....

Hi,
try to implement the Interface MouseListener (or the corresponding MouseAdapter):
eg:
class DrawingToolFrame extends JFrame implements ActionListener, MouseListener{
//add a MouseListener to the component withing you would like to fetch the mouse-coordinates
yourPanel.addMouseListener(this);
//implement the five methods of the MouseListener
public void mouseClicked(MouseEvent�e){}
public void mouseEntered(MouseEvent�e){}
public void mouseExited(MouseEvent�e) {}
public void mousePressed(MouseEvent�e){}
public void mouseReleased(MouseEvent�e){
e.getX(); //Coordinates of the mouse after releasing the button
e.getY();
