frameRect()

QRectF NonPdfCropping::frameRect

(

)

const

Frame rectangle selected by user.

Definition at line 81 of file NonPdfCropping.cpp.

{
  // The x(), y(), pos(), rect() and boundingRect() will return coordinates assuming origin at the initial position of
  // each handle. So to get the coordinates in the window reference frame it takes a two step process like
  // QGraphicsRectItem::mapRectToScene (QGraphicsRectItem::rect())

  QRectF rectTL = m_handleTL->mapRectToScene (m_handleTL->boundingRect());
  QRectF rectBR = m_handleBR->mapRectToScene (m_handleBR->boundingRect());

  QRectF rectUnited = rectTL.united (rectBR);

  return rectUnited;
}

moveBL()

void NonPdfCropping::moveBL	(	const QPointF &	newPos,
