Hi.
Lately I've been working on an Android application using the native Android
style available in Qt 5.4 as described in:
http://blog.qt.io/blog/2014/12/03/native-android-style-in-qt-5-4/
Everything has been working fine with the exception of QSlider.
When using a QSlider horizontally the groove is filled from left to right
with the minimum value on the left and the maximum value on the right, like
this:
0 =========[]-------- 100
And that's fine.
But when you set the QSlider to vertical position the groove is filled from
top to bottom; this is really counter-intuitive for the user, as you would
expect the groove to be filled from the minimum to the maximum.

This seems to only happen when using the Android style, as I have
cross-compiled the code to work as a windows applications and there the
slider is drawn correctly.
I have attached pictures of the same code running on Windows and Android
where you can appreciate the behavior.
I have tried using the function setInvertedAppearance() but that doesn't
have the required effect.
Also I have tried overriding the paintEvent() function and using
QStylePainter::drawComplexControl to draw the slider using a custom
QStyleOptionSlider object (changing its upsideDown and direction
properties) but that didn't work either.
Does anyone know what causes this to happen? Or how could I make it so that
the QSliders appear in Android like they do in Windows?
