  //x-offset is half of first label width because labels are drawn centered
  QString firstLabel = firstLabelString();
  double firstLabelWidth = QgsComposerUtils::textWidthMM( mFont, firstLabel );

  mStyle->draw( painter, firstLabelWidth / 2 );

  //draw frame and selection boxes if necessary
  drawFrame( painter );
