Member Function Documentation

addProvider()

void QgsProviderSourceWidgetProviderRegistry::addProvider

(

QgsProviderSourceWidgetProvider *

provider

)

Add a provider implementation. Takes ownership of the object.

Definition at line 35 of file qgsprovidersourcewidgetproviderregistry.cpp.

createWidget()

QgsProviderSourceWidget * QgsProviderSourceWidgetProviderRegistry::createWidget	(	QgsMapLayer *	layer,
		QWidget *	parent = nullptr
	)

Creates a new widget to configure the source of the specified layer.

It may return nullptr if no provider was found. The returned object must be destroyed by the caller.

Definition at line 96 of file qgsprovidersourcewidgetproviderregistry.cpp.

initializeFromProviderGuiRegistry()

void QgsProviderSourceWidgetProviderRegistry::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 52 of file qgsprovidersourcewidgetproviderregistry.cpp.

operator=()

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

delete

QgsProviderSourceWidgetProviderRegistry cannot be copied.

providerByName()

QgsProviderSourceWidgetProvider * QgsProviderSourceWidgetProviderRegistry::providerByName

(

const QString &

name

)

Returns a provider by name or nullptr if not found.

Definition at line 69 of file qgsprovidersourcewidgetproviderregistry.cpp.

providers()

QList< QgsProviderSourceWidgetProvider * > QgsProviderSourceWidgetProviderRegistry::providers

(

Definition at line 30 of file qgsprovidersourcewidgetproviderregistry.cpp.

providersByKey()

QList< QgsProviderSourceWidgetProvider * > QgsProviderSourceWidgetProviderRegistry::providersByKey

(

const QString &

providerKey

)

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

Definition at line 82 of file qgsprovidersourcewidgetproviderregistry.cpp.

removeProvider()

bool QgsProviderSourceWidgetProviderRegistry::removeProvider

(

QgsProviderSourceWidgetProvider *
