Detailed Description

A custom event that is designed to be fired when a layer count has been fully calculated.

This custom QEvent is designed to be fired when the full item count of a layer has been calculated. It was initially included in QGIS to help the QgsPostgresProvider provide the asynchronous calculation of PostgreSQL layer counts.

Events are used instead of Qt signals/slots as events can be received asynchronously, which makes for better mutlithreading behaviour and less opportunity for programmer mishap.
