[osg-users] Scroll not working properly on MacOS

[Bruno Oliveira]

Hello,

in MacOS, when using Qt as a frontend manager along with OSG contexts, I
realised that scrolling with external mouse is not working properly: if I
use the TrackballManipulator, all the mouse does is zooming in. However, if
I use the laptop's trackpad, the zoom works fine.
I think this may be related to Qt directly.I am catching Mouse events and
passing them via the osg getEventQueue() and  osgGA::GUIEventAdapters.

Does anyone has a hint on why is this happening?
