How to detect the orientation of device ?

[Dipakbaviskar]

Hi,

My application supports only portrait mode, which I specified in
BaseConstructL(EAppOrientationPortrait) in AppUi class.

I want to show up dialog when users switch from portrait to landscape mode.

I tried to used CAknAppUiBase::Orientation() function in HandleResourceChangeL function , But it gives me orientation of Application which is portrait.

How I detect the orientation of device when the orientation is changed from Portrait to Landscape.

You would get a notification when the screen orientation changes in

void HandleScreenDeviceChangedL();

So just implement this in your appui class.

Hi Mayur,

Thank you very much for quick reply.

I don’t have a problem with notification of change orientation, But i want to check device current orientation i.e. whether device is in portrait or landscape Mode.

Check these API with SDK Help:

TAppUiOrientation CAknAppUiBase::Orientation()
CAknAppUiBase::SetOrientationL  (  TAppUiOrientation  aOrientation   )

You can call these function directly from your AppUi class.

Hi,

I dont want to support Landscape mode for my application, so i define it in
BaseConstructL(EAppOrientationPortrait) like this.


The problem is when orientation is changed, HandleResourceChangeL() is called twise which gives me value for aType as

aType = KEikMessageUnfadeWindows in first call.

aType = KeikMessageWindowsFadeChange in second call.


Above as I set that application supports only EappOrientationPortrait forcefully in BaseConstructL() function,

due to that I didnt get the aType value which is define in akndef.h except KEikMessageWindowsFadeChange.

When device orientation changed from portrait to landscape i have to show global dialog to inform user that application not support landscape mode.

AknAppUiBase::Orientation() gives only application orientation, which is always return me EappOrientationPortrait.

Is their any interface through which I get the event of Screen Orientation changed and API for getting current orientation the device have rather than my application ?

Consider using GetScreenModeSizeAndRotation:

CWsScreenDevice* screen = CCoeEnv::Static()->ScreenDevice();
if (screen)
{
TInt mode = screen->CurrentScreenMode();
TPixelsTwipsAndRotation sizeAndRotation;
screen->GetScreenModeSizeAndRotation(mode, sizeAndRotation);
// now check sizeAndRotation.iRotation

TBool ScreenState()
{
TRect rect( iAppView1->ClientRect());
if( rect.iBr.iX < rect.iBr.iY ) // Portrait
{
return ETrue;
}
else
{
return EFalse;
}
