Member Function Documentation

◆ addProvider()

void QgsSubsetStringEditorProviderRegistry::addProvider ( QgsSubsetStringEditorProvider * provider )

Add a provider implementation. Takes ownership of the object.

Definition at line 37 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 98 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 54 of file qgssubsetstringeditorproviderregistry.cpp.

◆ operator=()

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

delete

◆ providerByName()

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

Returns a provider by name or nullptr if not found.

Definition at line 71 of file qgssubsetstringeditorproviderregistry.cpp.

◆ providers()

QList< QgsSubsetStringEditorProvider * > QgsSubsetStringEditorProviderRegistry::providers ( )

Gets list of available providers.

Definition at line 32 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 84 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
