[osg-users] Problems add a viewer

[alvaro ginestar rodriguez]

Hi everyone, I have a function that returns the viewer settings, but not pass it on to the viewer as the main function, any suggestions?the fuction is that:
osgViewer::Viewer multiventana(int x, int y, int alto, int ancho, int numColumns, int numRows){
	osgViewer::Viewer viewer;
	int tileWidth = alto / numColumns;	int tileHeight = ancho / numRows;	for (int i = 0; i<numRows; ++i)	{		for (int j = 0; j<numColumns; ++j)		{			osg::ref_ptr<osg::Camera> camera = createSlaveCamera((tileWidth*j) + x, (ancho - tileHeight*(i + 1)) + y, tileWidth - 1, tileHeight - 1);			osg::Matrix projOffset = osg::Matrix::scale(numColumns, numRows, 1.0) *	osg::Matrix::translate(numColumns - 1 - 2 * j, numRows - 1 - 2 * i, 0.0);			viewer.addSlave(camera, projOffset, osg::Matrix(), true);		}	}	return viewer;}
