Member Function Documentation
◆ blockingFetchTileRawData()
|
static |
Returns raw tile data for the specified range of tiles. Blocks the caller until all tiles are fetched.
Definition at line 161 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 68 of file qgsvectortileloader.cpp.
◆ loadFromMBTiles()
|
static |
Returns raw tile data for a single tile loaded from MBTiles file.
Definition at line 211 of file qgsvectortileloader.cpp.
◆ loadFromNetwork()
|
static |
Returns raw tile data for a single tile, doing a HTTP request. Block the caller until tile data are downloaded.
Definition at line 187 of file qgsvectortileloader.cpp.
◆ tileRequestFinished
|
signal |
Emitted when a tile request has finished. If a tile request has failed, the returned raw tile byte array is empty.
