Detailed Description

This class keeps a list of subset string editor providers.

QgsSubsetStringEditorProviderRegistry is not usually directly created, but rather accessed through QgsGui::subsetStringEditorProvideRegistry().

Member Function Documentation

◆ addProvider()

void QgsSubsetStringEditorProviderRegistry::addProvider ( QgsSubsetStringEditorProvider provider)

Add a provider implementation. Takes ownership of the object.

Definition at line 36 of file qgssubsetstringeditorproviderregistry.cpp.

◆ createDialog()

QgsSubsetStringEditorInterface * QgsSubsetStringEditorProviderRegistry::createDialog ( QgsVectorLayer layer,
QWidget *  parent = nullptr,
Qt::WindowFlags  fl = QgsGuiUtils::ModalDialogFlags 
)

Creates a new dialog to edit the subset string of the provided layer.

It will default to returning a QgsQueryBuilder* if no provider was found. The returned object must be destroyed by the caller.

Definition at line 97 of file qgssubsetstringeditorproviderregistry.cpp.

◆ initializeFromProviderGuiRegistry()

void QgsSubsetStringEditorProviderRegistry::initializeFromProviderGuiRegistry ( QgsProviderGuiRegistry providerGuiRegistry)

Initializes the registry.

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

Definition at line 53 of file qgssubsetstringeditorproviderregistry.cpp.

◆ operator=()

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

QgsDataItemProviderRegistry cannot be copied.

◆ providerByName()

QgsSubsetStringEditorProvider * QgsSubsetStringEditorProviderRegistry::providerByName ( const QString &  name)

Returns a provider by name or nullptr if not found.

Definition at line 70 of file qgssubsetstringeditorproviderregistry.cpp.

◆ providers()

QList< QgsSubsetStringEditorProvider * > QgsSubsetStringEditorProviderRegistry::providers ( )

Gets list of available providers.

Definition at line 31 of file qgssubsetstringeditorproviderregistry.cpp.

◆ providersByKey()

QList< QgsSubsetStringEditorProvider * > QgsSubsetStringEditorProviderRegistry::providersByKey ( const QString &  providerKey)

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

Definition at line 83 of file qgssubsetstringeditorproviderregistry.cpp.

◆ removeProvider()

bool QgsSubsetStringEditorProviderRegistry::removeProvider ( QgsSubsetStringEditorProvider provider)

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

Returns
true if the provider was actually removed and deleted
