示例1: boundsOfChildren
QRectF boundsOfChildren( QGraphicsItem const * qgi )
{
typedef QList<QGraphicsItem*> QGIL;
QGIL ch( qboard::childItems(qgi) );
QRectF r;
for( QGIL::const_iterator it = ch.begin();
ch.end() != it; ++it )
{
QGraphicsItem const * x = *it;
QRectF r2( x->mapToParent(x->pos()), x->boundingRect().size() );
r = r.unite( r2 );
}
if(1 && ! r.isNull() ) qDebug() << "bounds of children ="<<r;
return r;
}示例2:
QRectF k9CanvasSprite::boundingRect() const {
QRectF r;
if (m_pixmap){
r=m_pixmap->boundingRect();
r.moveTopLeft(m_pixmap->pos());
}
if (m_text) {
QRectF r2=m_text->boundingRect();
r2.moveTopLeft(m_text->pos());
r=r.unite(r2);
}
r.adjust(-m_selsize,-m_selsize,m_selsize,m_selsize);
