*
|
|
* base class for all graphical objects (panel, taskbar, task, systray, clock, ...).
|
|
* Area is at the begining of each object (&object == &area).
|
|
*
|
|
* Area manage the background and border drawing, size and padding.
|
|
* Each Area have 2 Pixmap (pix and pix_active).
|
|
*
|
|
* Area also manage the tree of visible objects. Parent object drawn before child object.
|
|
* panel -> taskbars -> tasks
|
|
* -> systray -> icons
|
|
* -> clock
|
|
*
|
|
* draw_foreground(obj) is virtual function.
|
|
*
|
|
* TODO :
|
|
* 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()
|
|
* voir config(obj) configure un objet (définie les positions verticales)
