Are you displaying the image in Applet....
You can use something like this...
void panel_mouseDragged(MouseEvent e) {
Container c = this.getParent();
if (c instanceof JViewport) {
JViewport jv = (JViewport) c;
Point p = jv.getViewPosition();
int newX = p.x - (e.getX()- m_XDifference);
int newY = p.y - (e.getY()- m_YDifference);
int maxX = this.getWidth() - jv.getWidth();
int maxY = this.getHeight() - jv.getHeight();
if (newX < 0)
newX = 0;
if (newX > maxX)
newX = maxX;
if (newY < 0)
newY = 0;
if (newY > maxY)
newY = maxY;
jv.setViewPosition(new Point(newX, newY));
void panel_mousePressed(MouseEvent e) {
setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
m_XDifference = e.getX();
m_YDifference = e.getY();
void panel_mouseReleased(MouseEvent e) {
setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
}
