- The dtscreen client supports the following key tasks.
-
- - Draws an animated image on a provided window id(s).
-
- - Does not assume the size of the provided window(s).
-
- - Provides a set of selectable animated images.
-
- - Animation parameters such as nice, speed, number and
- saturation may be specified.
-
- The dtscreen client provides the default screen saver
- animations for the desktop. When launched, it will query the
- desktop using the API for the set for window ids on which to
- draw. These window ids could be the cover windows created by
- the session manager for session lock, or a window imbedded
- in the style manager's session lock customization dialog.
- Once obtained, the dtscreen client will proceed to draw in
- these windows using the specified options. If dtscreen
- cannot obtain the set of window ids, it will create its own.
- Normally, the dtscreen client will be invoked directly by
- the session manager, or by the style manager.
-
- Note that the Session Manager, dtsession, is responsible for
- locking the session and prompting for a password to unlock.
-
- The session manager may launch the dtscreen client to
- provide screen saver animations during session lock. Refer
- to the session manager specification for resources
- controlling the launching of screen savers by the session
- manager.
-
- The style manager may launch the dtscreen client to provide
- a preview of a screen saver animation during customization.
- Refer to the style manager specification for information on
- how to integrate a screen saver client such as dtscreen into
- the desktop.
-
- The dtsession client provides a selectable set of
- animations. These are:
