Hi,
I'm creating map group objects and add them to a map. Once I remove them
my app segfaults. To me it looks like a bug, but before I file it it
would be nice if someone could tell me that I'm using the API correctly.
In a subclass of QGraphicsGeoMap I'm creating map objects like this:
void MapWidget::addPoi(double lat, double lon, QString uuid)
{
QGeoCoordinate coord(lat, lon);
QPixmap pixmap(":qml/Common/img/poi_green.png");
QGeoMapPixmapObject *pixMapObject = new QGeoMapPixmapObject(coord,
QPoint(-20,-70), pixmap);
pixMapObject->setZValue(1);
QGeoMapCircleObject *circle = new QGeoMapCircleObject(coord, 100);
circle->setPen(QPen((QColor(255, 0, 0, 90))));
circle->setBrush(QBrush(QColor(255, 0, 0, 90)));
circle->setZValue(2);
QGeoMapGroupObject *poi = new QGeoMapGroupObject();
poi->addChildObject(circle);
poi->addChildObject(pixMapObject);
addMapObject(poi);
}
Now if I later call clearMapObjects() or removeMapObject() it crashes.
If I directly add circle objects or pixmap objects without using a group
everything works fine.
Below is also a stack trace.
Cheers,
Conny
