BUG? item.setPos( qpf ) not working when item is part of a QGraphicsItemGroup

[muenalan]

Is this intended, or shall I file a bug ? I really spent hours to trace why I was not able to place the titem_title QGraphicsTextItem at the proper position (decorating my items).

Hope it helps others and here is code that circumvents this limitation.




void
QGraphicsItemGroupDERIVED::update()
{
#define CERRD std::Cerr

this->removeFromGroup( this->titem_title );

QTransform t;

t.setMatrix( this->transform().m11(), this->transform().m12(), 0, 0, 0, 0, 0, 0, 0 );

this->titem_title->setTransform( t );

this->titem_title->setPos( this->sceneBoundingRect().topLeft() );

this->addToGroup( this->titem_title );



CERRD << endl << "ITEM = " << this->name_get().toStdString() << endl;

if( this->titem_title->sceneBoundingRect().topLeft() != this->sceneBoundingRect().topLeft() )
{
CERRD << "*** WARNING *** setPos on titem failed." << endl;
}

CERRD << "item actualpos = " << this->sceneBoundingRect().topLeft() << endl;
CERRD << "titem_title actualpos = " << titem_title->sceneBoundingRect().topLeft() << endl;
}


Cheers,

Could you provide a minimal compilable example reproducing the problem?
