Re: [Qgis-developer] some trouble with pointers in my c++-plugin





Thank you for your reply,
i tried this but in the first case QGis crashes on refreshing. What do I 
wrong? It seems to be so easy...

                QgsPoint pt;
                double myX=440000.0;//(*adress->X);
                double myY=570000.0;//(*adress->Y);
                if (adress->geom==0)
                {
                        //pt=QgsPoint(myX,myY);
                        pt=QgsPoint(440000.0,570000.0);
                        qDebug()<<"Geom is null"<<"X="
<<QString::number(pt.x())<<"Y="<<QString::number(pt.y());
                }
                else
                {
                        pt = adress->geom->asPoint();
                        qDebug()<<"Geom is valid"<<"X="
<<QString::number(pt.x())<<"Y="<<QString::number(pt.y());
                }
                QgsRectangle extent( pt.x() - 50.0,  pt.y() - 50.0, pt.x() 
+ 50.0,  pt.y() + 50.0);
                mQGisIface->mapCanvas()->setExtent(extent);
                mQGisIface->mapCanvas()->refresh();

I think you need to use a reference instead of a pointer as the argument.
