[Débutant] Déplacement contrôles customisés et détection collision régions GDI

Bonsoir,

Je recherche une aide pour gérer le déplacement par la souris ou les flèches de 2 contrôles créés dans l'application. Ces contrôles sont destinés à simuler des paquets placés sur une palette.

L'application doit gérer les éventuelles collisions entre paquets, avec l'outil de préhension et fournir les coordonnées de chaque paquet posé sur la palette.

Le principe est le suivant :

l'opérateur place chaque paquet (ControlRgn) sur la palette (panel1)

mes problèmes sont les suivants :

_ comment gérer le déplacement du paquet par la souris (éviter la déformation, suivre exactement le curseur)

_ comment détecter les collisions entre régions GDI

_ comment ajouter un paquet sur la palette (Panel1.Controls.Add(paquet)) ne "mémorise" pas le paquet

Voici une partie de mon code, si vous pouvez m'aider.....

merci

Code:
