Bonjour ,

Il me reste 10 jours à mon pfe.
Je voudrais afficher le chemin suivit(parcourit) sur la carte google maps.
Je voudrais que le chemin soit affiché sur le route et non pas sur une liason entre deux points seulement.
Mais je voudrais que le liason entre le points suivent le route de la carte goole maps.



comme dans cette image:

voila mon code :
Code : Sélectionner tout - Visualiser dans une fenêtre à part
