The return values of QMimeData::hasFormat() and QMimeData::data() are inconsistent with the documentation.

QMimeData mimeData;

    mimeData.setData( "text/uri-list", "test" );

    qDebug() << "mimeData.hasFormat( \"text/plain\" )" << mimeData.hasFormat( "text/plain" );

    qDebug() << "mimeData.data( \"text/plain\" )" << mimeData.data( "text/plain" );

    qDebug() << "mimeData.hasFormat( \"text/uri-list\" )" << mimeData.hasFormat( "text/uri-list" );

    qDebug() << "mimeData.data( \"text/uri-list\" )" << mimeData.data( "text/uri-list" );

    qDebug() << "mimeData.hasText()" << mimeData.hasText();

    qDebug() << "mimeData.text()" << mimeData.text();
