[osg-users] osgQtBrowser - compile problem

Hi JS,

I can't recall the difference in behavior between with and without
setStickyFocus(), but it'll probably be related to how the texture
cursor behaves.  As this method isn't available in older versions of
Qt then I'd suggest adding an #ifdef around it.

Robert.
