exception sur un lookanfeel

**Blo0d4x3** · 10/02/2006, 03h21

Salut tous, je voudrais que mon application ait le meme style que celle du systeme.
Je fais donc ceci:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

try
		{
			UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
			SwingUtilities.updateComponentTreeUI(this);
 
		}
		catch (UnsupportedLookAndFeelException ex1) 
		{
 
			System.err.println("Unsupported LookAndFeel");
 
		}
 
		catch (ClassNotFoundException ex2) 
		{
 
			System.err.println("LookAndFeel class not found");
 
		}
 
		catch (InstantiationException ex3) 
		{
			System.err.println("Could not load LookAndFeel");	
		}

Mais ca me sort un exception :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Unhandled exception type IllegalAccessException

Ai-je oublier d'importer une librairie ou autre?

Je suis sous eclipse, merci de votre aide.

Il te manque le catch de IllegalAccessException.

**Blo0d4x3** · 10/02/2006, 15h50

arf oui quel ane :-(.

Je dois passer quoi comme parametre a UIManager.setLookAndFeel() pour avoir le style du système?

Merci

**natha** · 10/02/2006, 15h52

Perso j'utilise la librairie Looks de JGoodies et ça donne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1

		String lafName = Options.getCrossPlatformLookAndFeelClassName();
		try {
			UIManager.setLookAndFeel(lafName);
		} catch (Exception e) {
			System.err.println("Can't set look & feel:" + e);
		}

Réfléchi un peu et relis mon post. J'utilise quelque chose que toi sûrement pas, j'te donnais juste une indic...

**MeDioN** · 10/02/2006, 16h24

Je pense que c'est la même exception qui se propage -_-

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

  try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    } catch(Exception e) {
      System.out.println(e);
    }

Aucune raison que ça na marche pas ça (c'est comme natha)

**natha** · 10/02/2006, 16h38

Je pense que le code MeDioN marchera oui.
Son exception c'est parce qu'il essaie d'utiliser le LnF de JGoodies sans avoir la librairie dans son classpath donc forcément, null pointer !
