[Qgis-developer] Labeling in vector layer (development on Qt)

[hubbatov]

One more problem: how to disable rendering too many labels (overlapped
labels) ?

I tried this code:

bool inSets = QgsProject::instance()->readBoolEntry("PAL",
"/ShowingAllLabels");
QgsPalLabeling* mPal =
(QgsPalLabeling*)m_map->mapCanvas()->mapRenderer()->labelingEngine();
mPal->setShowingAllLabels(false);
mPal->willUseLayer(layer);
qDebug() << "IS SHOWING ALL LABELS:" << mPal->isShowingAllLabels() <<
inSets;

It shows me that label overlapping is off, but it is on! What to do?
