Detailed Description

This class keeps a list of source select providers that may add items to the QgsDataSourceManagerDialog When created, it automatically adds providers from data provider plugins (e.g.

PostGIS, WMS, ...)

QgsSourceSelectProviderRegistry is not usually directly created, but rather accessed through QgsGui::sourceSelectProviderRegistry().

Note
This class access to QgsProviderRegistry instance to initialize, but QgsProviderRegistry is typically initialized after QgsGui is constructed, for this reason a delayed initialization has been implemented in the class.
Since
QGIS 3.0
