Hi i have an applet which has a frame and several panelsthat are loaded on the frame. I need to put an image which acts as a header and the panels should be loaded below the header image. How can i do this. Can anyone post a sample code here.

Thank you
Ram

Hi.

You can also put this code as:

Image myimg ;
in init() function :

myimg = Toolkit.getDefaultToolkit().getImage(<absolutepath> );

and in paint or repaint functions you can use the same
top level reference of Image class as follows:

g.drawImage( myimg, <x>, <y>, this );

here, you need to import classes appropriately.
Toolkit comes from java.awt.Toolkit here.
and remember one thing absolute path would not contain
backward slashes, they will be forward only.
for example in d drive suppose you have first.gif then
you have to give "d:/first.gif" .

-Arun.

HI, i tried toolkit, it gave me the following errors

pine 382% javac WaltzPanel.java
WaltzPanel.java:1531: Incompatible type for method. Can't convert java.lang.String to byte[].
     logo = toolkit.createImage(nanocadHome + "\\logo.jpg");
                                            ^
WaltzPanel.java:1536: Incompatible type for method. Can't convert java.awt.Image to java.awt.Component.
        PageLogoPanel.add(logo);
                          ^
Note: WaltzPanel.java uses a deprecated API.  Recompile with "-deprecation" for details.

Since security issues limit you to use external files.You can use URL class.It will give best result.

Code:
import java.net.*;
import javax.swing.*;
-
---
URL url=getClass().getResource("india.gif");
Icon ic=new ImageIcon(url);

JLabel label=new JLabel(ic);
(or)
label.setIcon(ic);
