本文演示如何使程序运行时屏幕常亮，避免屏保和黑屏
Introduction
使用QMl的ScreenSaver Element可以轻松的保持屏幕常亮
import QtMobility.systeminfo 1.1
ScreenSaver
{
screenSaverDelayed:true
}
也可使用ScreenSaver自带的setScreenSaverDelayed(bool) 方法在适当的时候启动屏幕常亮，例如
import QtMobility.systeminfo 1.1
import com.meego 1.0
ScreenSaver
{
id:screenSaver
}
Button{
text: "on"
onClicked:screenSaver.setScreenSaverDelayed(true)
}
}
注意使用Qt Mobility 在Pro文件中加入声明
CONFIG += mobility
MOBILITY += systeminfo
代码示例：Media:Screensa.zip
