Hi,

It should work like in MSPaint. The line should follow the mouse as the mouse is dragged.

What I did is:
private int xBegin;
private int yBegin;

private void drawPanelMousePressed(java.awt.event.MouseEvent evt)
{
     xBegin = evt.getX();
     yBegin = evt.getY();
}

private void drawPanelMouseDragged(java.awt.event.MouseEvent evt) {
       Graphics g = drawPanel.getGraphics()
       g.drawLine(xBegin, yBegin, evt.getX(), evt.getY());
       drawPanel.paintComponents(g);    
}


The problem is: It draws new lines as mouse is dragged. Somehow I should remember the original graphics before mouse is pressed. Adding a field and initializing it during mousePress did not work. Probably I have to clone the Graphics object. How can I do that? Or are there any easier ways?

mygraphics.create() method did not work either.
