TableSpanExtentDelegate typedef

TableSpanExtentDelegate = SpanExtentDelegate

Delegate passed to TableSpanExtent.calculateExtent from the RenderTableViewport during layout.

Provides access to metrics from the TableView that a TableSpanExtent may need to calculate its extent.

Extents will not be computed for every frame unless the delegate has been updated. Otherwise, after the extents are computed during the first layout passed, they are cached and reused in subsequent frames.

Implementation

typedef TableSpanExtentDelegate = SpanExtentDelegate;
