Cette classe represente une ligne pouvant etre utilisee pour composer le
|
|
dessin d'un element dans l'editeur d'element.
|
|
Une ligne est composee de deux points. Elle peut comporter des extremites
|
|
speciales definissables grace aux methodes setFirstEndType et
|
|
setSecondEndType. La taille des extremites est definissable via les
|
|
methodes setFirstEndLength et setSecondEndLength.
|
|
A noter que les extremites ne sont pas dessinees si la longueur requise
|
|
pour leur dessin n'est pas contenue dans la ligne. S'il n'y a de la place
|
|
que pour une seule extremite, c'est la premiere qui est privilegiee.
