utilisation tool man drag

Bonjour,

J'utilise la fonction de drag de tool man.
J'ai plusieurs div draggables.
Voici comment je leur affecte la possibilitée d'être draggé dans une zone précise (zone de contrainte):
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 for(j=1;j<=nbDiv;j++) { var drag = ToolMan.drag(); var coordinates = ToolMan.coordinates() var box = document.getElementById('id_div'+j); //On rend le div draggable(box = div a draggé, et document.getElementById("handle"+j) = zone a cliquer pour dragger l'objet group = drag.createSimpleGroup(box,document.getElementById("handle"+j)); group.addTransform(function(coordinate,dragEvent) { var xhautgauche=getOffsetPosition('OrangeEditeur', 'Left')-26; var yhautgauche=getOffsetPosition('OrangeEditeur', 'Top'); var xbasdroite=document.getElementById("OrangeEditeur").offsetWidth+xhautgauche-box.offsetWidth+25; var ybasdroite=document.getElementById("OrangeEditeur").offsetHeight+yhautgauche-box.offsetHeight-2; //Coin haut gauche de contrainte var origin = coordinates.create(xhautgauche,yhautgauche); //Coin Bas droite de contrainte var origin2=coordinates.create(xbasdroite,ybasdroite); return coordinate.constrainTo(origin, origin2); }) }
Le problème, c'est qu'ils sont tous contraints par rapport à la taille du dernier div...(Voir le code qui est en rouge)

Comment faire pour que les coordonnées du point en bas à droite corresponde à la taille du div dragué et non à celles du dernier div crée?

Si vous voulez je peux vous mettre le code des fonctions de drag...

Comment récupérer l'id du div qui est draggé en temps réel?

Si ca peut aider, je met le code source des fonctions de drag:
