Member Function Documentation

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

previewItem()

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.

scrollPointOnPoint()

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

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

setItem()

void Digikam::GraphicsDImgView::setItem

(

GraphicsDImgItem *const

item

)

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

Note

if you store a GraphicsDImgItem object, previewItem() will return 0.
