hi everyone !! i would like make a class and function for make a window in osg,
i have this source, but when i tried them separately, it have errors.The file
"DemoVentana.cpp"it does well, but the other one no.
#include "Ventana.h"
osg::Camera* createCamera(int x, int y, int w, int h)
{
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits;
traits->x = x;
traits->y = y;
traits->width = w;
traits->height = h;
traits->doubleBuffer = true;
traits->windowName = "Funcion de Ventana";
traits->windowDecoration = true;
osg::ref_ptr<osg::GraphicsContext> gc = osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc.get());
camera->setViewport(new osg::Viewport(0, 0, traits->width, traits->height));
return camera.release();
}#ifndef H_VENTANA
#define H_VENTANA
#include <osg/Group>
#include <osgViewer/Viewer>
class Ventana
{
public:
osg::Camera* createCamera(int x, int y, int w, int h);
};

camera->setViewport(new osg::Viewport(0, 0, traits->width, traits->height));
return camera.release();
}
