本文演示如何使程序运行时屏幕常亮,避免屏保和黑屏

[edit] 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
