I am wondering if I have to do to save the shape files. Below is the code I am
using. I am able to create memory layers that I could save later. But I want to
create many shapefiles and QGIS started to run out of memory when I was loading
the memory shapefiles. Once I change the provider to OGR and give the path and
basename, it gets a NULL provider.
Can some of the QGIS Master's help a novice?
QString mPath = ("c:/tmp/qgis/");
QString mBaseName = ("BikeNA");
QString provLib="ogr";
QgsVectorLayer* vl = 0;
vl = new QgsVectorLayer( mPath, mBaseName, provLib );
QgsVectorDataProvider *prov = vl->dataProvider();
prov->addAttributes( attrList );
vl->startEditing();
QgsFeature f;
featureList::Iterator it;
for ( it = featureList.begin(); it != featureList.end();it++)
{
f = *it;
vl->addFeature( f );
}
vl->updateExtents();
vl->endEditCommand();
vl->commitChanges();
Maaza
