Hi All,
is there anybody that can explain me please why (at least in OSG 3.4.0) in
CompositeViewer.cpp, inside eventTraversal() method, the return value of
GUIEventHandle::handle(...) is not used?
Here is a code snippet:
Code:
for(ViewEventsMap::iterator veitr = viewEventsMap.begin();
veitr != viewEventsMap.end();
++veitr)
{
View* view = veitr->first;
_eventVisitor->setActionAdapter(view);
for(osgGA::EventQueue::Events::iterator itr = veitr->second.begin();
itr != veitr->second.end();
++itr)
{
osgGA::Event* event = itr->get();
for(View::EventHandlers::iterator hitr =
view->getEventHandlers().begin();
hitr != view->getEventHandlers().end();
++hitr)
{
(*hitr)->handle( event, view, _eventVisitor.get());
}
}
}
Please look at the line:
(*hitr)->handle( event, view, _eventVisitor.get());
While GUIEventHandler::handle method returns bool as you can see in the
following code:
Code:
bool GUIEventHandler::handle(osgGA::Event* event, osg::Object* object,
osg::NodeVisitor* nv)
{
osgGA::EventVisitor* ev = dynamic_cast<osgGA::EventVisitor*>(nv);
osgGA::GUIEventAdapter* ea = event->asGUIEventAdapter();
if (ea && ev && ev->getActionAdapter())
{
#if 1
bool handled = handle(*ea, *(ev->getActionAdapter()), object, nv);
if (handled) ea->setHandled(true);
return handled;
#else
Regards,
Gianni
