Next: Object Sharing Between Scenes
Up: Multimedia and Hypermedia Information
For objects that are visible on the screen, the following rules apply :
- Objects are drawn downwards and to the right of their position
on the screen. This point can be changed during the life
cycle of an object, thus making it possible to move objects.
- Objects are drawn without scaling. Objects that do not fit
within their bounding box are clipped.
- Objects are drawn with "natural" priority, i.e., on top of
already existing objects. However, it
is possible to move objects to the top or the bottom of the screen, as well as putting them
before or after another object.
- The screen can be frozen, allowing the application to perform
many (possibly slow) changes and
not update the screen until it's unfrozen.
