 * base class for all graphical objects (panel, taskbar, task, systray, clock, ...).
-* Area is at the begining of each graphical object so &object == &area.
-* 
+* Area is at the begining of each object (&object == &area).
+*
 * Area manage the background and border drawing, size and padding.
-* Area also manage the tree of visible objects
+* Each Area have 2 Pixmap (pix and pix_active).
+*
+* Area manage the tree of all objects. Parent object drawn before child object.
 *   panel -> taskbars -> tasks
 *         -> systray -> icons
 *         -> clock
-* 
-* draw_foreground(obj) and draw(obj) are virtual function.
-* 
-* resize_width(obj, width) = 0 : fonction virtuelle à redéfinir
-*    recalcule la largeur de l'objet (car la hauteur est fixe)
-*    - taille systray calculée à partir de la liste des icones
-*    - taille clock calculée à partir de l'heure
-*    - taille d'une tache calculée à partir de la taskbar (ajout, suppression, taille)
-*    - taille d'une taskbar calculée à partir de la taille du panel et des autres objets
-* 
-* voir resize_taskbar(), resize_clock() et resize_tasks()
-* variable widthChanged ou bien emission d'un signal ???
-* voir config(obj) configure un objet (définie les positions verticales)
