Enabling auto-rotation

So, 24/04/2011 - 01:22

Hello, when testing my application on the ExoPC with MeeGo, it ignores display rotations that do work in other applications. How to enable automatic display rotation for my application? In the internet I found e. g.


#ifdef Q_WS_MAEMO_5
    w.setAttribute(Qt::WA_Maemo5AutoOrientation, true);
#endif

but this doesn't work for me. Best regards and thanks for tips Andreas

Hello,

still I did not get the automatic display rotation to work.

I tried to find out something with the Qt docu, but as far as I understood the automatic rotation should work without any code change needed. Therefore I don't understand why this is not working for my app. :-(

That's my simple main method - nothing special here. What additional setting I have to add to get an automatic display rotation applied to my app?
int main(int argc, char *argv[])
{
QApplication a(argc, argv);

MainWindow w;
w.showMaximized();

return a.exec();
}

Best regards and thanks in advance
Andreas

Hello Kiran,

unfortunately I do not have a solution for this issue yet.

Maybe somebody else here has an idea about that.

Best regards

Hi Andreas:

i do not believe MAMEO pragma flags will work on MeeGo.

Can you look into this class:

http://doc.qt.nokia.com/4.7-snapshot/qgraphicsrotation.html

and see if this can be applied to your code?

Hello Vincent,

yes, I've saw the class already, but it just looks not the right way for me.

Because what I am searching for is just a way the application is rotated automatically when the device is rotated as e. g. also the AppUp client application itself.

So there should just be a flag or something like that telling MeeGo that it can rotate this application if needed automatically.

Best regards
Andreas

Hello everybody,

is it not the MSceneManager that handle most of the Rotation Scene process ?
for example it has this method,
/*!
* Returns the current orientation. It's a convenience method with
* which you can get the orientation without querying the application window.
*/
M::Orientation orientation() const;

and some signal , slot to force the rotation

Hello David,

thanks for your reply.

And how I can tell this MSceneManager to just rotate the application when the sensor detects a device rotation (the same way as it's done with other applications (like the AppUp client itself) on the device)?

Best regards

Hello Andreas,

i guess probably like does the widget gallery demo

applicationWindow()->setOrientationAngleLocked(false);
applicationWindow()->setOrientationLocked(false);
} else if (mode == portrait) {
applicationWindow()->setOrientationAngleLocked(false);
applicationWindow()->setOrientationAngle(M::Angle270);
applicationWindow()->setOrientationLocked(true);
} else if (mode == landscape) {
applicationWindow()->setOrientationAngleLocked(false);
applicationWindow()->setOrientationAngle(M::Angle0);
applicationWindow()->setOrientationLocked(true);
} else if (mode == angle0) {

and of course a connect to the public slot of the sceneManager :
void orientationAboutToChange(M::Orientation orientation);
void orientationAngleChanged(M::OrientationAngle orientationAngle);

that will be how i will try do to it .
Kind regards

david
