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().

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 99 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 55 of file qgssourceselectproviderregistry.cpp.

◆ operator=()

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

QgsDataItemProviderRegistry cannot be copied.

◆ providerByName()

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

Returns a provider by name or nullptr if not found.

Definition at line 72 of file qgssourceselectproviderregistry.cpp.

◆ 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 85 of file qgssourceselectproviderregistry.cpp.

◆ removeProvider()

bool QgsSourceSelectProviderRegistry::removeProvider ( QgsSourceSelectProvider provider)
