Force display orientation to Portrait

[blackbird700]

I am beginner at mobile applications programming.
My app has to be run in portrait mode, and I don't know how to ignore sensor reading, and autorotate...

I've found this:
http://wiki.forum.nokia.com/index.ph...Qt_for_Symbian

but it's not working... I've got Qt 4.6 with Symbian SDK (~900MB download from http://www.forum.nokia.com/info/sw.n...ia_Qt_SDK.html)
did i missed something?

The code in that first link is what you need (though obviously you should specify Portrait rather than Landscape).

You say "it's not working" -- do you mean it won't compile, or it fails somehow when executed?

when I say it's not working, I mean it compiles, but when executed, it doesn't force orientation (i tried both simulator and nokia5800). I replaced Landscape with Portrait. When I paste code from link, it is underlined yellow in QtCreator...

You did put the code where it would be executed, right? Before the first show of the main screen?

Have you verified that the test for null isn't no-oping the operation? (I prefer using a Q_ASSERT, since the value should never be null.)

Also, the link is wrong in using dynamic_cast -- that form of cast is unreliable at best in Qt (and Symbian generally). In extreme cases it can actually cause physical damage to the phone.

Use "reinterpret_cast" instead.

ok, I downloaded and installed S60 SDK, and now it works on phone (it doesn't work on simulator, but i don't care for simulator)
Thanks to danhicksbyron!

I used reinterpret_cast..

I was wondering if there is now a simpler way of disabling auto rotation? Would it be possible by using something like QOrientationSensor?

[danhicksbyron]

Nope. All that does is let you read the accelerometer.

[Sasler]

So is there another way then?

[danhicksbyron]

Use the Symbian code. It's the only way I know of.
