I have the class CropImage that works correctly, the method start is created and there I generate a JFrame decorado that should show the current image that is drawn in ImagePanel .
If I put an absolute address works but only with the image that is happening, but the reality is that you should read the current image that is drawn at that time in ImagePanel ... Any ideas?
public class CropImage extends JFrame implements MouseListener, MouseMotionListener
{
int drag_status = 0, c1, c2, c3, c4;
private final LineBorder border = new LineBorder(Color.RED,1);
JMenuBar JMenuCropped = new JMenuBar();
JMenu JMenuCropped1 = new JMenu();
JMenu JMenuCropped2 = new JMenu();
JMenu JMenuCropped3 = new JMenu();
public void start()
{
//Aquí funciona con una dirección absoluta
ImagePanel im = new ImagePanel("C:.........");
add(im);
setUndecorated(true);
getRootPane().setBorder(border);
setFocusable(true);
getContentPane().add(JMenuCropped, BorderLayout.NORTH);
setSize(550,550);
setLocation(460,180);
setVisible(true);
addMouseListener(this);
addMouseMotionListener(this);
JMenuCropped.setPreferredSize(new Dimension(35,35));
JMenuCropped.add(JMenuCropped1);
JMenuCropped.add(JMenuCropped2);
JMenuCropped.add(JMenuCropped3);
JMenuCropped1.setIcon(new javax.swing.ImageIcon(
getClass().getResource("/iconos/verde_c.png"))
);
JMenuCropped1.setToolTipText("Minimize window");
JMenuCropped1.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e){
setExtendedState(JFrame.NORMAL);
}
});
JMenuCropped2.setIcon(
new javax.swing.ImageIcon(getClass().getResource("/iconos/amarillo_c.png"))
);
JMenuCropped2.setToolTipText("Maximize window");
JMenuCropped2.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e){
setExtendedState(getExtendedState()| FramePrincipal.MAXIMIZED_BOTH);
}
});
JMenuCropped3.setIcon(
new javax.swing.ImageIcon(getClass().getResource("/iconos/rojo_c.png"))
);
JMenuCropped3.setToolTipText("Close window");
JMenuCropped3.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e){
setVisible(false);
}
});
