hi!
Yes, I got it! thanks a lot... I'm attaching a sample code (very
small) as to how I did it. Please do tell me if there's a better way than
this.
#include <osgViewer/Viewer>
#include <osgViewer/CompositeViewer>
#include <osgDB/ReadFile>
#include <iostream>
using namespace std;
osg::ref_ptr<osg::Node> model;
osgViewer::CompositeViewer* cViewer;
int composite = 0;
class Keyboard : public osgGA::GUIEventHandler{
public:
Keyboard():
_mx(0.0f), _my(0.0f){}
virtual bool handle(const osgGA::GUIEventAdapter& ea,
osgGA::GUIActionAdapter& aa){
osgViewer::Viewer* viewer =
dynamic_cast<osgViewer::Viewer*> (&aa);
if (ea.getEventType() ==
osgGA::GUIEventAdapter::KEYDOWN){
if (ea.getKey() == 'c'){
cout << "Viewer changed!!" << endl;
cViewer = new
osgViewer::CompositeViewer;
cViewer->addView(viewer);
composite = 1;
viewer->setDone(true);
}
}
}
private:
float _mx, _my;
};
int main(int argc, char **argv){
osgViewer::Viewer* viewer = new osgViewer::Viewer;
model = osgDB::readNodeFile(argv[1]);
viewer->setSceneData(model.get());
viewer->addEventHandler(new Keyboard);
viewer->run();
if (composite)
return cViewer->run();
return 0;
}
thanks a lot.
bye!
