◆ bestRepresentativeIndexFromList()

QPersistentModelIndex Digikam::MapViewModelHelper::bestRepresentativeIndexFromList	(	const QList< QPersistentModelIndex > &	list,
		const int	sortKey
	)

overridevirtual

This function finds the best representative marker from a group of markers. This is needed to display a thumbnail for a marker group.

Parameters

indices	A list containing markers.
sortKey	Determines the sorting options and is actually of type GPSItemInfoSorter::SortOptions

Returns: Returns the index of the marker.

Reimplemented from Digikam::GeoModelHelper.

◆ itemCoordinates()

bool Digikam::MapViewModelHelper::itemCoordinates	(	const QModelIndex &	index,
		GeoCoordinates *const	coordinates
	)		const

overridevirtual

Gets the coordinates of a marker found at current model index.

Parameters

index	Current model index.
coordinates	Here will be returned the coordinates of the current marker.

Returns: True, if the marker has coordinates.

Implements Digikam::GeoModelHelper.

		QPoint *const	offset,
		QSize *const	size,
		QPixmap *const	pixmap,
		QUrl *const	url
	)		const

virtualinherited

these are necessary for ungrouped models

Returns the icon for an ungrouped marker.

The icon can either be returned as a URL to an image, or as a QPixmap. If the caller can handle URLs (for example, to display them in HTML), he can provide the URL parameter. However, the GeoModelHelper may still choose to return a QPixmap instead, if no URL is available.

Parameters

index	Modelindex of the marker.
offset	Offset of the zero point in the icon, given from the top-left.
size	the size of the icon, only populated if a URL is returned.
pixmap	Holder for the pixmap of the icon.
url	URL of the icon if available.

Reimplemented in Digikam::GPSBookmarkModelHelper, and DigikamGenericGeolocationEditPlugin::SearchResultModelHelper.

◆ onIndicesClicked()

void Digikam::MapViewModelHelper::onIndicesClicked ( const QList< QPersistentModelIndex > & clickedIndices )

overridevirtual

This functions is called when one clicks on a thumbnail.

Parameters

clickedIndices A list containing the marker indices belonging the group whose thumbnail has been clicked.

Reimplemented from Digikam::GeoModelHelper.

◆ onIndicesMoved()

void Digikam::GeoModelHelper::onIndicesMoved	(	const QList< QPersistentModelIndex > &	movedIndices,

	)

◆ pixmapFromRepresentativeIndex()

QPixmap Digikam::MapViewModelHelper::pixmapFromRepresentativeIndex	(	const QPersistentModelIndex &	index,
		const QSize &	size
	)

overridevirtual

This function retrieves the thumbnail for an index.

Parameters

index	The marker's index.
size	The size of the thumbnail.

Returns: If the thumbnail has been loaded in the ThumbnailLoadThread instance, it is returned. If not, a QPixmap is returned and ThumbnailLoadThread's signal named signalThumbnailLoaded is emitted when the thumbnail becomes available.

Reimplemented from Digikam::GeoModelHelper.
