Is there a system suspend event in AIR?

Can an Adobe AIR applica开发者_如何学Pythontion detect when the host system is put to sleep/suspend?

check out the userIdle event from the flash.desktop.NativeApplication class.

you may also prevent the system from becoming idle by setting the systemIdleMode property:

//Prevent
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;

//Allow
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.NORMAL;

if neither of those options suit your needs, you can always use NativeProcess to handle processes on the host operating system.
