mx.core.Application, which
is the main "top-level" window within an application.
Every application has an ISystemManager. The ISystemManager sends an event if the size of the application window changes (you cannot change it from within the application, but only through interaction with the operating system window or browser). It parents all displayable items within the application, such as the main mx.core.Application instance and all popups, tooltips, cursors, an so on. Any object parented by the ISystemManager is considered to be a "top-level" window, even tooltips and cursors.
The ISystemManager also switches focus between top-level windows if there are more than one IFocusManagerContainer displayed and users are interacting with components within the IFocusManagerContainers.
All keyboard and mouse activity that is not expressly trapped is seen by the ISystemManager, making it a good place to monitor activity should you need to do so.
If an application is loaded into another application, an ISystemManager
will still be created, but will not manage an "application window",
depending on security and domain rules.
Instead, it will be the content of the Loader
that loaded it and simply serve as the parent of the sub-application
The ISystemManager maintains multiple lists of children, one each for
tooltips, cursors, popup windows.
This is how it ensures that popup windows "float" above the main
application windows and that tooltips "float" above that
and cursors above that.
If you examine the numChildren property
or getChildAt() method on the ISystemManager
you are accessing the main application window and any other windows
that aren't popped up.
To get the list of all windows, including popups, tooltips and cursors,
use the rawChildren property.
