* Tasks Data Engine
|
|
*
|
|
* This engine provides information regarding tasks (windows that are currently open)
|
|
* as well as startup tasks (windows that are about to open).
|
|
* Each task and startup is represented by a unique source. Sources are added and removed
|
|
* as windows are opened and closed. You cannot request a customized source.
|
|
*
|
|
* A service is also provided for each task. It exposes some operations that can be
|
|
* performed on the windows (ex: maximize, minimize, activate).
|
|
*
|
|
* The data and operations are provided and handled by the taskmanager library.
|
|
* It should be noted that only a subset of data and operations are exposed.
