The program has unexpectedly finished

Bonjour à tous!! J’ai un petit problème, en fait je suis en train de faire une application pour dessiner des triangles, cercles, segment, et rectangles pour dessiner chaque forme il faut appuyer sur le buttons destine pour chaqu'un voilà je fais mon dessine mais après je voudrais appuyer sur un bouton pour déplacer le groupe de formes et un bouton pour déplacer chaqu'un individuellement et là j'ai des problèmes quand j'appuie sur le bouton et lorsque j'essaie de cliquer sur la forme:



The program has unexpectedly finished : /

je vous remercie pour l'aide car j'ai pas d'idee de comme resoudre cette probleme

Voici mon code:

j'ai cree chaque forme en utilisant cycles for

Bonjour,
il y juste un problème de pointeurs qui peuvent être pas initialisés dans la méthode rotation_forme() apparemment.
donc dans le constructeur de Dialog tu dois rajouter :

Code:

---

1 2 3 4

cerclee=0; rectangle=0; trianglee=0; segment=0;

---

et mettre dans la methode rotation_forme() :

Code:

---

1 2 3 4 5 6 7 8

if(cerclee) cerclee->setFlag(QGraphicsItem::ItemIsMovable); if(rectangle) rectangle->setFlag(QGraphicsItem::ItemIsMovable); if(trianglee) trianglee->setFlag(QGraphicsItem::ItemIsMovable); if(segment) segment->setFlag(QGraphicsItem::ItemIsMovable);

voilà.sinon à part celà apparemment je n'ai pas vu d'autres problèmes (compilé avec Qt 5.4.1)
bonne journée
