Disable Screensaver

[OscarBernabeu]

To disable the automatic screensaver lock-on and dim light:

-I have to include QtMobility on the .pro file:

CONFIG += mobility
MOBILITY += systeminfo


-Use QSystemScreenSaver->setScreenSaverInhibit():

 #include <QSystemScreenSaver>

QSystemScreenSaver *sss=new QSystemScreenSaver ( this );
sss->setScreenSaverInhibit();

My problem is I don't know if this code is right and where and how to include it. I was looking at the QtMobility examples but I cant figure out. Can anybody help me?

Hi,
the code looks right.

you can add that functionality to one of your classes like shown below

#include <QObject>
#include <QSystemScreenSaver>

class myClass : public QObject
{
Q_OBJECT
public:
explicit myClass(QObject *parent = 0): sss(0){}

void setScreenSaverInhibit(bool inhibit) ){
if (inhibit) {
if (sss) return;
sss = new QSystemScreenSaver (this);
sss->setScreenSaverInhibit();
} else {
delete sss;
sss = 0;
}
}
private:
QSystemScreenSaver *sss

};

Thanks for your answer. Im trying to figure out where do I have to include the code:

at the main.cpp? at qmlapplicationviewer.h?

Sorry but I have no clue.

BTW,

It seems it can be done from QML using QTMobility:

http://doc.qt.nokia.com/qtmobility-1...reensaver.html

But I cant make it work either.

Ok, I got it.

To disable de screensaver using QtMobility:

-Enable QtMobility on the .pro file:

 CONFIG += mobility
 MOBILITY += systeminfo

-Import QtMobility at the start of your main.qml file with this line:

 import QtMobility.systeminfo 1.1

-Add this element to your main.qml file:

    ScreenSaver { id: screenSaver
        Component.onCompleted: {screenSaver.setScreenSaverDelayed(true) }
    }

Hi Oscar,
I have used that code but it does not dim the lights? Did your use dim the lights as well?
Thanks,

What this code does is disable the screensaver and *avoid* the lights dim.

ah ok, is there code that dims the lights as well? I have made a QML flip clock but I wanted an option for the user to leave it as a screen saver. If I use the code, screensaver is off, but the lights are still with big battery draw.
