Manipulation de polygone

Question

Bonjour a tous 


J'essaye actuellement de faire un programme qui manipule des polygones.

J'ai une frame avec a gauche des boutons et des listes et des textfields et a droite un panel ou il y a les polygones ( 1 pour commencer)

ce ke j'essaye de faire en vain: rotate et drag mon polygone. Le faire rotationner en fonction dune valeur sélectionnée dans une jlist ou bien dune valeur entrée dans une textfield cad un angle. L'angle est bien un double. 

J'ai essaye plusieurs codes trouves sur le net mais mon polygone ne daigne pas tourner...

Autre prob j'essaye de le déplacer avec la souris : j'ai implemente mousedragged et mousereleased mais mon polygone reste toujours a sa place.

Ce n'est pas un devoir a faire a la maison: je ne suis pas étudiant en informatique. Mais j'aime Java et j'essaye de faire des progs car ça me plait. 

Quelques conseils seraient les bienvenus.

UP jarrive a dessiner un polygone a main levee, mais il ne sarrete pas, a chaque clic il cree un point.... jarrive toujours pas a supprimer le polygone que je selectionne, ni a le drag/drop, ni a le redimensionner.
