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. | |

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. | |
