Hi guys,
I need to insert drawables like lines, polygons to the viewer.
Then, the idea it's to create an osgWidget::Box and insert through the
method getGeode()->addDrawable a simple drawable...

}
return mainBox.release();
}
int main(int argc, char** argv)
{
osgViewer::Viewer viewer;
osg::ref_ptr<osgWidget::WindowManager> wm = new
osgWidget::WindowManager(&viewer, 1024.0f, 768.0f, 0xf0000000);
osg::Camera* camera = wm->createParentOrthoCamera();
wm->addChild(createSimpleTabs(0.0f, 0.0f));
wm->resizeAllWindows();
osg::ref_ptr<osg::Group> root = new osg::Group;
root->addChild(camera);
viewer.setSceneData(root.get());
viewer.setUpViewInWindow(50, 50, 1024, 768);
viewer.addEventHandler(new osgWidget::MouseHandler(wm.get()));
viewer.addEventHandler(new osgWidget::KeyboardHandler(wm.get()));
viewer.addEventHandler(new osgWidget::ResizeHandler(wm.get(), camera));
viewer.addEventHandler(new osgWidget::CameraSwitchHandler(wm.get(),
camera));
return viewer.run();
}
What I get is to have the two labels in the hbox .. but I can't see the
line ...
What am I doing wrong?
