HI,

In a B4XPages project, I need to know if the device orientation is in portrait or landscape

Thank you

Patrick

    If Root.Width > Root.Height Then
        Log("landscape")
    Else
        Log("portrait")
    End If

Since you can't really change the orientation in a B4XPages project, it should be same you specified in the main module attributes

Thank you @klaus , but I agree with @Alessandro71 :
I just want to get the information : how the user hold his device : horizontally (landscape) or vertically (portrait)

Thanks

Alessandro meant something different, that with the B4XPages you are the one who establishes the orientation of the APP and therefore you know it a priori.

Instead, you need an event that informs you when the user rotates the device.

When I have woken up for good, after enjoying a good coffee, maybe I'll try to answer you; I'm afraid I know the answer only for B4A-Android and maybe you want to develop for iOS too (I'm not sure, since B4XPages is still worth using even if you don't intend to do the latter).

If you need the orientation that the phone is held, see
https://www.b4x.com/android/forum/threads/orientation-and-accelerometer.6647/post-476271

I just ran the example, and you need to experiment with the thresholds for the orientation(1) values (vertical plane) - the example uses orientation(0) (horizontal plane).

Sorry @LucaMs we answered at the same time.

Sorry @LucaMs we answered at the same time.

In fact I was going to answer, but differently.

For B4A you can use the OrientationChanged event of the Phone library.

P.S. But the coffee wasn't good enough

This should work with B4i; it's the first one i found and since i don't have B4i ...!
