Hi, I have a panel, say WorkPanel for which the OverlayLayout is set. I have placed one image into it. And when I click on any area of the image i want to add a textarea (JTextArea) over the image. (ie for adding comments to the image) Now when i add textarea its getting added to the correct position. But when I start typing on the first textarea, all the textareas are moved to the centre of the image, overlapping each other. I am including the code here public class WorkPanel extends JPanel { public void paintComponent(Graphics g) { super.paintComponent(g); //Draw image g.drawImage(img, sx, sy, this); repaint(); }

Hi,
I have a panel, say WorkPanel for which the OverlayLayout is set.
I have placed one image into it. And when I click on any area of the image i want to add a textarea (JTextArea) over the image. (ie for adding comments to the image)
Now when i add textarea its getting added to the correct position. But when I start typing on the first textarea, all the textareas are moved to the centre of the image, overlapping each other. I am including the code here
public class WorkPanel extends JPanel
{
public void paintComponent(Graphics g)
{
super.paintComponent(g);
//Draw image
g.drawImage(img, sx, sy, this);
repaint();
}
...
...
OverlayLayout overlay = new OverlayLayout(this);
this.setLayout(overlay);
this.addMouseListener(new ImageMotionListener(this));
this.addMouseMotionListener(new ImageMotionListener(this);
...
...
}
On mouse click event
public void mouseClicked(MouseEvent me)
{
int x = me.getX();
int y = me.getY();
JTextArea cb = new JTextArea("comm :");
Dimension dim = new Dimension(60, 50);
cb.setSize(dim);
cb.setMinimumSize(dim);
cb.setMaximumSize(dim);
cb.setPreferredSize(dim);
cb.setLocation(x,y);
workPanel.add(cb);
}
Also when i type on the textarea its not getting expanded as and when i enter contents into it. For this I removed "cb.setMaximumSize(dim)". Then immedietly when i start typing the textarea got expanded to the fullsize of the workpanel.
Also when i removed "cb.setSize(dim)" textarea was not visible.
what could be the problem?
regards
anu.
