GWT Designer (Création graphique de composants)
Bonjour à tous
J'ai installé le plugin GWT Designer/WindowBuilder version 1.7 pour eclipse Ganymede 3.4 afin de pouvoir dessiner mes formulaires plus aisément grace au WYSIWYG et la bibliothèque GWT-EXT, mais je n'arrive pas à afficher la partie design de la classe générée.
Voici le code généré lorsque je crée un Window à l'aide de WindowBuilder :

package com.gwt.ext.test.client;
import com.gwtext.client.widgets.Window;
public class TestWindowGWTExt extends Window {
public TestWindowGWTExt() {
super("New window");
setSize("350px", "200px");
}
} |
et voici l'erreur qui s'affiche dans l'onglet design lorsque je cherche à afficher le rendu :

Je peux déjà vous confirmer qu'au niveau du code source, il nya aucune erreur (pas même un warning).
Quelqu'un aurait-il déjà utilisé plugin pour la création d'interfaces graphiques avec GWT ? moi j'ai du mal en tout cas.
Merci
