Hi Mathias,
I have just modified the osgpick example to check for MOVE events and
it works perfectly.
switch(ea.getEventType())
{
case(osgGA::GUIEventAdapter::MOVE):
{
osgViewer::View* view = dynamic_castosgViewer::View*(aa);
if (view) pick(view,ea);
return false;
}
I don't know what you've done wrong, but perhaps you can look at the
attached osgpick.cpp for reference.
Robert.
