C++ (Cpp) QgsFields::allAttributesList Examples

Example #1

File: testqgsfields.cpp Project: p0cisk/Quantum-GIS

void TestQgsFields::allAttrsList()
{
    QgsFields fields;
    QgsAttributeList attrList = fields.allAttributesList();
    QVERIFY( attrList.isEmpty() );

    QgsField field( QString( "testfield" ) );
    fields.append( field );
    QgsField field2( QString( "testfield2" ) );
    fields.append( field2 );
    QgsField field3( QString( "testfield3" ) );
    fields.append( field3 );

    attrList = fields.allAttributesList();
    QCOMPARE( attrList.at( 0 ), 0 );
    QCOMPARE( attrList.at( 1 ), 1 );
    QCOMPARE( attrList.at( 2 ), 2 );
}
