[swing] [JTREE] problèmes d'affichage

Bonjour,

J'ai fait une appli qui fait un peu exploreur avec des options.
Mon problème est que lorsque j'ai des dossiers contenant beaucoup de fichier cela bloque mon appli.
Je ne sais pas trop comment faire.
J'ai redefinit la méthode

Code:

---

1 2 3

public Component getTreeCellRendererComponent(JTree tree,Object value ,boolean selected,boolean expanded ,boolean leaf,int row,boolean hasFocus)

---

dans une class qui extends DefaultTreeCellRenderer.
Cette méthode est appelée le nombre de fois qu'il y a de sous-dossier ou sous-fichier dans un dossier et dois sûrement s'executer dans l'EDT. Ce qui expliquerait mon problème. Mais je ne sais pas comment la faire executer dans un autre thread pour arrêter de bloquer l'EDT.

Voici la méthode en question :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

public Component getTreeCellRendererComponent(JTree tree,Object value ,boolean selected,boolean expanded ,boolean leaf,int row,boolean hasFocus){   JLabel label = (JLabel)super.getTreeCellRendererComponent(tree,value,selected,expanded,leaf,row,hasFocus); File fichier = (File)value; FileSystemView sys = FileSystemView.getFileSystemView(); String s = sys.getSystemDisplayName(fichier);   if(s.length()>3 && s.substring(s.length()-3,s.length()).equals("jpg")) { label.setText(s.substring(0,s.length()-4)+" "+dateFormat.format(new Date(fichier.lastModified()))); label.setIcon(sys.getSystemIcon(fichier)); } else{ label.setText(sys.getSystemDisplayName(fichier)); label.setIcon(sys.getSystemIcon(fichier)); } return label; }

---

Merci d'avance

Bonjour,

Je viens de me rendre compte que j'ai confondu IDE et EDT :oops:
Desoler:aie:

Donc je vais remplacer cela dans le post precedant.

ça sera surment plus claire

En cherchant du côté de swingworker j'ai changé ma jdk.(passage de la 5 à la 6)
Et sans rien faire, mon exploreur ne devient plus gris pendant la recherche des dossiers.
Néanmoins j'ai eu une erreur critique qui n'apparait pas à chaque fois :

Code:

Si quelqu'un peut m'expliquer...

Merci d'avance

Bonjour,

Je vais reformuler ma question sachant que je souhaite utiliser jre5:
Est il possible de faire faire des pauses au EDT quand il execute un code long ?
Dans mon cas j'aimerai lui imposer une pause dans la méthode getTreeCellRendererComponent.

Si cela n'est pas possible de "l'interrieur" comment puis je construire mon JTree de manière à ce que EDT fasse des pauses durant l'appel de la méthode getTreeCellRendererComponent ?

Merci d'avance
