Inheritance diagram for QgsVectorTileLoader:

Signals
void	tileRequestFinished (const QgsVectorTileRawData &rawTile)
	Emitted when a tile request has finished. If a tile request has failed, the returned raw tile byte array is empty.

Public Member Functions
	QgsVectorTileLoader (const QgsVectorTileDataProvider provider, const QgsTileMatrixSet &tileMatrixSet, const QgsTileRange &range, int zoomLevel, const QPointF &viewCenter, QgsFeedback feedback, Qgis::RendererUsage usage)
	Constructs tile loader for doing asynchronous requests and starts network requests.

	~QgsVectorTileLoader ()

void	downloadBlocking ()
	Blocks the caller until all asynchronous requests are finished (with a success or a failure)

QString	error () const
	Returns a eventual error that occurred during loading, void if no error.

	Returns raw tile data for the specified range of tiles. Blocks the caller until all tiles are fetched.

static

Returns raw tile data for the specified range of tiles. Blocks the caller until all tiles are fetched.

Definition at line 170 of file qgsvectortileloader.cpp.

◆ downloadBlocking()

void QgsVectorTileLoader::downloadBlocking ( )

Blocks the caller until all asynchronous requests are finished (with a success or a failure)

Definition at line 62 of file qgsvectortileloader.cpp.

◆ error()

QString QgsVectorTileLoader::error ( ) const

Returns a eventual error that occurred during loading, void if no error.

Definition at line 163 of file qgsvectortileloader.cpp.

◆ tileRequestFinished

void QgsVectorTileLoader::tileRequestFinished ( const QgsVectorTileRawData & rawTile )

signal

Emitted when a tile request has finished. If a tile request has failed, the returned raw tile byte array is empty.
