adding Frame to Applet

[simcel jones]

thanks for taking time to read this
I am trying to add a frame to an Applet
see below
import java.applet.*;
import java.awt.*;
public class BioApplet extends Applet {
public void init() {
Frame f=new Frame("f");
f.setBackground(Color.yellow);
add(f);
}
public void paint(Graphics g) {}
}
compile error code
java.lang.IllegalArgumentException: adding a window to a container

Simcel,
I don't think you can add a frame to an applet. A frame is its own window, with title bar, icon, etc. What was the goal here? Perhaps we can find you a better way to achieve it. Please let us know.

hi,
try to put a button that opens a frame as a new container instead of creating a frame on applet..

Hava a look at http://www.math.utwente.nl/~gragert/Live_Math/TaylorError.html

There is a green button (an applet) wich launches (or destroys) a frame.

Simcel,
You do not need to add the frame to the applet... simply remove the call :

add( f );

and replace it with the following to have your frame pop up when the applet is loaded :

f.setVisible( true );

As others have mentioned in this thread... it's a good idea to have some action on the users part control the opening of the frame... automatic pop up windows are annoying...
HTH,
-Nate

I have the same feeling as Nathan about 'automatic' popup windows. ;-)
