Bonjour,
J'ai une fenêtre sur laquelle j'ai fait un setUndecorated(true).
Sur son rootPane, j'ai rajouté un border.
J'ai créé une classe qui simule le redimenssionnement d'une fenêtre en se basant sur le border du contentPane(quand on clique sur le bord et qu'on bouge la souris, la fenêtre se redimenssione).
Mon problème est que le contenu de la fenêtre clignote lorsque je la redimmensionne.
Je pense que cavient du fait que pour redimenssionner je doit modifier la taille de la fenêtre, sa position, la taille du contentPane et la taille du rootPane. Tout ceci entraine 5 appels au repaint de la frame. Je pense que ca vient de la.
Apparemment c'est l'appel à la modification de la taille de la fenêtre qui crée le problème. Toutes les modifs sur la taille et la position sont faîtes à la fin du mouseDragged
Voici mon source si vous êtes disposé à m'aider :
