Resize et rotate impossible sur un rectangle dans un panel ?

**yonafunu** · 29/09/2015, 12h11

Bonjour à tous,

Je continue sur mon petit soft.
Je récapitule : je cherche à superposer un rectangle sur une image de fond, ce rectangle sera draggable, rotationable , et resizable (mais si c'est français...

)

J'ai donc reussi à faire en sorte qu'un rectangle imposé puisse etre déplacé grace à cette classe :

      x = e.getX();

      if (myRect.getBounds2D().contains(x, y)) {
        myRect.x += dx;
        myRect.y += dy;
        repaint();
      }
      x += dx;
      y += dy;
    }
  }
}

Je définie un rectangle à 200,200 en x/y de taille 800x800px.

Or je souhaiterai maintenant pouvoir modifier la taille de ce rectangle et le tourner si je clique sur le bouton Rotate de mon interface (par exemple 200,200, 300, 300). Resize et setBounds n'ont aucune effet sur la taille soit dit en passant...

Le bouton "Afficher" et "Rotate" ont la même fonction, je souhaitais, pour test, faire en sorte que Rotate change juste la taille du rectangle défini dans ma classe MouseMoveScale.
Du coup dans mon action de clic sur le bouton Rotate, j'ai " myRect.setBounds(100, 100, 300, 300);" qui je pensais m'aurais permis de changer les propriétés de mon rectangle. Pourquoi rien ne se passe dans ce cas ? Comment puis-je modifier mon rectangle défini dans mon autre classe lors d'un clic ?

Merci par avance pour votre aide

Setbounds est destiné au layoutmanager. Quelle que soit la valeur que tu y met, ce sera écrasé. Ce que tu dois faire c'est changer les dimension de ton objet rectangle utilisé par paint et rappeler repaint.

Merci de ta réponse.
D'accord pour setBounds.
Par contre peux tu m'indiquer un indice ou une voie pour changer les dimensions d'un rectangle d'un paint se situant dans une classe ? comment l'appeler dans ma classe principale dans mon cas ?

Merci
