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();
Freundliche Grüße aus Leipzig

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