Jpanel dans un Jpanel

**cotede2** · 08/07/2009, 00h03

Bonjour, je créé ma première interface avec Swing.

J'ai donc créé des panel dans ma JFrame:

LogoPanel
TitlePanel
MainPanel
MenuPanel

Et je voudrais pouvoir coder ces jpanel dans des classes à part.

Donc j'étends la classe Jpanel :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
public class LogoPanel extends javax.swing.JPanel {
 
    /** Creates new form LogoPanel */
    public LogoPanel() {
        initComponents();
    }....

ma classe interface :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
 
 
 logoPanel = new javax.swing.JPanel();
 logoPanel.add(new LogoPanel());
 logoPanel.repaint();

Mais au lancement de l'interface , le panel de logopanel ne s'affiche pas et de même pour tous les autres.

Comment faire? merci

Deja :

Il faudrait plus de code pour voir ce qui ne vas pas et qu'on puisse tester.
Tu peux deja verifier qu'il est bien ajoute a l'arborescence des composants existants, qu'il a une bonne taille, quel est le layout actuel de son composant parent et si ce meme layout ne fait pas qu'il soit retire si tu ajoutes un autre panel par derriere.

Dans ta classe interface le logoPane que tu cré est un JPanel et non un Logo Panel.
tu doit mettre :
private panels.LogoPanel logoPanel;

et
logoPanel= new LogoPanel();

Dans ta classe Interface, je verrais plutôt le constructeur comme ça:

        titrePanel.add(new TitlePanel());
        menuPanel.add(new MenuPanel());
        mainPanel.add(new MainPanel());
        pack();

private panels.LogoPanel logoPanel;

et
logoPanel= new LogoPanel();

je dois donc enlever le fichier .form ? et les balises <editor>?
Je peux uniquement travailler qu'avec le code et pas avec le mode design?

Non mais ceux qui veulent tester en ont besoin histoire de pouvoir excuter le programme. De meme que savoir quelle IDE tu utilises.

C'est quoi ? NetBeans ? Eclipse ? JBuilder ? un autre ?

On est pas devins non-plus...
