◆ drawText()

void Digikam::GraphicsDImgView::drawText	(	QPainter *	p,
		const QRectF &	rect,
		const QString &	text
	)

Note: Change from protected to public to be used by ImageRegionWidget and ImageRegionItem

DImgPreviewItem * Digikam::GraphicsDImgView::previewItem ( ) const

Returns: a cast of item instance of item set by setItem() as DImgPreviewItem

Note: if you store a GraphicsDImgItem object using setItem(), this method will return nullptr.

void Digikam::GraphicsDImgView::scrollPointOnPoint	(	const QPointF &	scenePos,
		const QPoint &	viewportPos
	)

E.g., calling scrollPointOnPoint(scenePos, viewport()->rect().center()) is equivalent to calling centerOn(scenePos).

void Digikam::GraphicsDImgView::setItem ( GraphicsDImgItem *const item )

You can store DImgPreviewItem object also by this method. Use item() or previewItem() to get right version.
