TileSourceDataChangedEventArgs¶
Namespace: ThinkGeo.Core
Says that the data behind a tile source changed, and over what ground, so a map drawing it forgets the tiles it has and asks again: the features behind a FeatureSourceVectorTileSource, or the pictures a RasterTileSource serves (RasterTileSource.Refresh(RectangleShape)).
public sealed class TileSourceDataChangedEventArgs : System.EventArgs
Inheritance object → EventArgs → TileSourceDataChangedEventArgs
Properties¶
Extent¶
Gets the ground the change covered, in the source's grid coordinates (web mercator metres for a web-mercator grid), or null when it could not be narrowed down - a deletion, for one, leaves only an id behind, so where the feature was is unknown. Null means every tile of the source is suspect.
public RectangleShape Extent { get; }
Property Value¶
Constructors¶
TileSourceDataChangedEventArgs(RectangleShape)¶
Initializes the arguments.
public TileSourceDataChangedEventArgs(RectangleShape extent)
Parameters¶
extent RectangleShape
The ground the change covered, or null for all of it.
