Hello All
Hopefully a simple question.
How do I get the text out of a picked drawable?
I need to reduce it to a simple char* string to pass it onto another
programming language for processing.
The following picker compiles except for the line:
osg::ref_ptr<osgText::Text> theText =
hitr->drawable.get();
of course?
Any idea what the correct syntax is for the cast?
Or is there a simpler way to accomplish this?
Thanks in advance for any advice.
void PickHandler::pick(osgViewer::View* view, const osgGA::GUIEventAdapter& ea)
{
osgUtil::LineSegmentIntersector::Intersections intersections;
float x = ea.getX();
float y = ea.getY();
if (view->computeIntersections(x,y,intersections))
{
for(osgUtil::LineSegmentIntersector::Intersections::iterator
hitr = intersections.begin(); hitr != intersections.end(); ++hitr)
{
if (hitr->drawable.valid())
{
std::cout << "Object \"" <<
hitr->drawable->className() << "\"" << std::endl;
osg::ref_ptr<osgText::Text> theText =
hitr->drawable.get();
if(theText)
{
osgText::String value =
theText->getText();
std::string cpptext =
value.createUTF8EncodedString();
const char *c = cpptext.c_str();
printf("Text choosen:%s\n",c);
}
}
}
}
}
