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().

Since: QGIS 3.0

Member Function Documentation

◆ addProvider()

void QgsSourceSelectProviderRegistry::addProvider ( QgsSourceSelectProvider * provider )

Add a provider implementation. Takes ownership of the object.

Definition at line 34 of file qgssourceselectproviderregistry.cpp.

◆ createSelectionWidget()

QgsAbstractDataSourceWidget * QgsSourceSelectProviderRegistry::createSelectionWidget	(	const QString &	name,
		QWidget *	parent,
		Qt::WindowFlags	fl,
		QgsProviderRegistry::WidgetMode	widgetMode
	)

Gets select widget from provider with name.

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

Since: QGIS 3.10

Definition at line 103 of file qgssourceselectproviderregistry.cpp.

◆ initializeFromProviderGuiRegistry()

void QgsSourceSelectProviderRegistry::initializeFromProviderGuiRegistry ( QgsProviderGuiRegistry * providerGuiRegistry )

Initializes the registry.

The registry needs to be passed explicitly (instead of using singleton) because this gets called from QgsGui constructor.

Since: QGIS 3.10

Definition at line 59 of file qgssourceselectproviderregistry.cpp.

◆ operator=()

QgsSourceSelectProviderRegistry & QgsSourceSelectProviderRegistry::operator= ( const QgsSourceSelectProviderRegistry & rh )

delete

QgsDataItemProviderRegistry cannot be copied.

◆ providerAdded

void QgsSourceSelectProviderRegistry::providerAdded ( const QString & name )

signal

Emitted whenever a provider is added to the registry.

Since: QGIS 3.30

◆ providerByName()

QgsSourceSelectProvider * QgsSourceSelectProviderRegistry::providerByName ( const QString & name )

Returns a provider by name or nullptr if not found.

Definition at line 76 of file qgssourceselectproviderregistry.cpp.

◆ providerRemoved

void QgsSourceSelectProviderRegistry::providerRemoved ( const QString & name )

signal

Emitted whenever a provider is removed from the registry.

Since: QGIS 3.30

◆ providers()

QList< QgsSourceSelectProvider * > QgsSourceSelectProviderRegistry::providers ( )

Gets list of available providers.

Definition at line 29 of file qgssourceselectproviderregistry.cpp.

◆ providersByKey()

QList< QgsSourceSelectProvider * > QgsSourceSelectProviderRegistry::providersByKey ( const QString & providerKey )

Returns a (possibly empty) list of providers by data providerkey.

Definition at line 89 of file qgssourceselectproviderregistry.cpp.

◆ removeProvider()

bool QgsSourceSelectProviderRegistry::removeProvider ( QgsSourceSelectProvider * provider )

Remove provider implementation from the list (provider object is deleted)

Returns: true if the provider was actually removed and deleted
