Sure!
Maybe I'm missing some important change in OSG 1.2 regarding event
handling... btw code is long, here posting handle() function:
bool BoostManipulator::handle(const GUIEventAdapter& ea,GUIActionAdapter&
us){
switch( ea.getEventType() ){
// ...
// other "cases"
// ...
case(GUIEventAdapter::SCROLL):{
addMouseEvent(ea);
osg::notify(ALWAYS) << "Scroll\n"; // This line is printed
when
I scroll, OK
if ( MouseListener() ) us.requestRedraw();
us.requestContinuousUpdate(true);
return true;
}
case(GUIEventAdapter::SCROLL_UP):{
addMouseEvent(ea);
osg::notify(ALWAYS) << "Scroll-up\n"; // NOT PRINTED!!!
if ( MouseListener() ) us.requestRedraw();
us.requestContinuousUpdate(true);
return true;
}
case(GUIEventAdapter::SCROLL_DOWN):{
addMouseEvent(ea);
osg::notify(ALWAYS) << "Scroll-down\n"; // NOT PRINTED!!!
if ( MouseListener() ) us.requestRedraw();
us.requestContinuousUpdate(true);
return true;
}
}
Ah, I see, SCROLL_UP and SCROLL_DOWN aren't event-types, they are
scrollMotions. It seems, that the code got refactored a while back.
I think the correct way to handle scrolling-events is:
switch (ea.getEventType()) {
case GUIEventAdapter::SCROLL:
case ea.getScrollMotion() {
case GUIEventAdapter::SCROLL_DOWN:
//handle scroll down;
break;
case GUIEventAdapter::SCROLL_UP:
//handle scroll up
break;
}
break;
// case other_event_types...
}
HTH,
