awt - sizing frame container by its contents

[Alex]

Hello all!

I need to set correct frame size by its contents (applet). I tried
pack(), it shrinks frame making it too small.
How to size frame by its content, or how to set preferred size ?
AWT (note, AWT-only, no swing!) code:

//Main method
public static void main(String[] args) {
applet = new MicroCadApplet();
frame = new ContainerFrame();

frame.add(applet, BorderLayout.CENTER);
frame.setSize(applet.getWidth()+10,
applet.getHeight()+30);


Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
frame.setLocation((d.width - frame.getSize().width) / 2,
(d.height - frame.getSize().height) / 2);
frame.setVisible(true);

Plz do not send me to java.sun.com tutorials, its about swing.

pack() should be the right method. If it doesn't work, then the
getPreferredSize() method(s) of the contents of the frame are bad.

Note that there is enough commonality between Swing and the AWT to
justify doing the Swing tutorial even if you only need the AWT.

E.G. This tutoral page on layouts mentions 6 layouts, only two
of which are Swing, the rest are AWT.
<http://java.sun.com/docs/books/tutorial/uiswing/layout/using.html>

Further, this page on Swing painting mentions the java.awt classes
Graphics and Graphics2D, as well as PrintJob and PrinterJob
<http://java.sun.com/docs/books/tutorial/uiswing/14painting/concepts2.html>

I suspect the reason for this is that Sun is now concentrating on
documenting Swing, rather than the AWT. They seem to be aiming at
an integrated 'how to make a UI' approach in the Swing tutorial, while
only working to document the parts of the AWT -not- -covered- by the
Swing tutorial.

For a tutorial focussed on the AWT itself, you might try..
