There was a mistake in my previous message. I was testing the code after
subtle changes but I forgot to change it back to normal... (But it doesn't
work all the same...)
bool PickHandler::handle(const osgGA::GUIEventAdapter& ea,
osgGA::GUIActionAdapter& aa)
{
osgViewer::Viewer* viewer = dynamic_cast<osgViewer::Viewer*>( &aa );
osgUtil::LineSegmentIntersector::Intersections intersections;
if(!viewer)
{ return false; }
switch(ea.getEventType())
{
case(osgGA::GUIEventAdapter::PUSH):
{
if(Intersecao(viewer, ea, intersections))
{
osg::notify(osg::NOTICE)<< "SELECAO" << std::endl;
for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr =
intersections.begin(); hitr != intersections.end();
++hitr)
{
osg::notify(osg::NOTICE)<< "ENTERED THE FOR" <<
std::endl;
if(hitr->drawable.valid()) // it was written
'!hitr->drawable.valid()', but I've corrected it
{
osg::notify(osg::NOTICE)<< "ENTERED HERE" <<
std::endl;
osg::ShapeDrawable* shapedrawable =
dynamic_cast<osg::ShapeDrawable*>(hitr->drawable.get());
shapedrawable->setColor(osg::Vec4(1.0, 0.0, 0.0,
1.0));
}
}
}
}
}
}
bool PickHandler::Intersecao(osgViewer::Viewer* viewer, const
osgGA::GUIEventAdapter& ea,
osgUtil::LineSegmentIntersector::Intersections
intersections)
{
return (viewer->computeIntersections(ea.getX(),ea.getY
(),intersections));
}
