Hi ,

 I have JFrame, over which i have a JInternalFrame. On this JInternalFrame i am displaying an Image using JPanel, ie JPanel which contains the image is placed on JInternalFrame.

Code is like this.

class myclass extends JPanel{
...
----
// constructor
myclass()
{
-- --
--
JScrollPane scroll = new JScrollPane(this);

}

}
i have set the color of scrollpane to white(for testing the presence)

When the image is displayed the scrollpane appears as a bar next to image,
when the image is zoomed, this bar disappears and the image is zoomed, but no scrollbars appear.

can i get help for this,

regards

You need to set the preferred size of your panel.
override getPreferredSize() method to return appropriate sizxe.
