Java Look and Feel

try {
        UIManager.setLookAndFeel(
            UIManager.getCrossPlatformLookAndFeelClassName());
    } catch (Exception e) { }

der er mange muligheder:

UIManager.getCrossPlatformLookAndFeelClassName()
Returns the string for the one look-and-feel guaranteed to work -- the Java look and feel.
UIManager.getSystemLookAndFeelClassName()
Specifies the look and feel for the current platform. On Microsoft Windows platforms, this specifies the Windows look and feel. On Mac OS platforms, this specifies the Mac OS look and feel. On Sun platforms, it specifies the CDE/Motif look and feel [PENDING: check].
"javax.swing.plaf.metal.MetalLookAndFeel"
Specifies the Java look and feel. (The codename for this look and feel was Metal.) This string is the value returned by the getCrossPlatformLookAndFeelClassName method.
"com.sun.java.swing.plaf.windows.WindowsLookAndFeel"
Specifies the Windows look and feel. Currently, you can use this look and feel only on Microsoft Windows systems.
"com.sun.java.swing.plaf.motif.MotifLookAndFeel"
Specifies the CDE/Motif look and feel. This look and feel can be used on any platform.

min favorit er "Kunststoff"
Kan hentes gratis her: http://www.incors.org/

Bruges således:
UIManager.setLookAndFeel(new com.incors.plaf.kunststoff.KunststoffLookAndFeel());

Hvor er det lige jeg skal sætte try blokken ind henne?

Jeg har en main der initiere en new MyGUI som igen har en init og eller construktoren!

en init OG en construktor mener jeg

du skal indsætte try blokken som det første i din construktor

Det vil den tilsyneladende bare ikke være med til
Kan det have noget med XP at gøre?

nej, der har ikke noget med xp at gøre.

Prøv at smide din GUI kode her.

Der er sgu meget... det er lavet med JBuilder!!..

WinXP Look and Feel vha. UIManager.getCrossPlatformLookAndFeelClassName());
virker først fra JDK 1.4.2 beta

k
Så er det derfor den ikke vil...

Lige en kort bemærkning...

Nogle gange skrives der System.exit(1) og nogle gange System.exit(0)
Hvad er forskellen?

API'en siger følgende:

exit
public static void exit(int status)Terminates the currently running Java Virtual Machine. The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination.
This method calls the exit method in class Runtime. This method never returns normally.

The call System.exit(n) is effectively equivalent to the call:

Runtime.getRuntime().exit(n)

Parameters:
status - exit status.
Throws:
SecurityException - if a security manager exists and its checkExit method doesn't allow exit with the specified status.
See Also:
Runtime.exit(int)
