Class: QgsSourceSelectProviderRegistry¶

class qgis.gui.QgsSourceSelectProviderRegistry¶

Bases: sip.wrapper

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()

Methods

`addProvider`	Add a `provider` implementation.
`createSelectionWidget`	Gets select widget from provider with `name`
`initializeFromProviderGuiRegistry`	Initializes the registry.
`providerByName`	Returns a provider by `name` or `None` if not found
`providers`	Gets list of available providers
`providersByKey`	Returns a (possibly empty) list of providers by data `providerkey`
`removeProvider`	Remove `provider` implementation from the list (`provider` object is deleted)

addProvider(self, provider: QgsSourceSelectProvider)¶

Add a provider implementation. Takes ownership of the object.

createSelectionWidget(self, name: str, parent: QWidget, fl: Union[Qt.WindowFlags, Qt.WindowType], widgetMode: QgsProviderRegistry.WidgetMode) → QgsAbstractDataSourceWidget ¶

Gets select widget from provider with name

The function is replacement of QgsProviderRegistry.createSelectionWidget() from QGIS 3.8

New in version 3.10.

Parameters

name (str) –
parent (QWidget) –
fl (Union[Qt.WindowFlags) –
widgetMode (QgsProviderRegistry.WidgetMode) –

Return type

QgsAbstractDataSourceWidget

initializeFromProviderGuiRegistry(self, providerGuiRegistry: QgsProviderGuiRegistry)¶

providers(self) → List[QgsSourceSelectProvider]¶

providersByKey(self, providerKey: str) → List[QgsSourceSelectProvider]¶
