Detailed Description

A registry / canonical manager of GUI parts of data providers.

QgsProviderGuiRegistry is not usually directly created, but rather accessed through QgsGui::providerGuiRegistry().

setPluginPath() should be called (once) to load dynamic providers. Static providers are loaded in constructor.
