Constructor & Destructor Documentation

◆ QgsAbstractDataSourceWidget()

QgsAbstractDataSourceWidget::QgsAbstractDataSourceWidget	(	QWidget *	parent = `nullptr`,
		Qt::WindowFlags	fl = `QgsGuiUtils::ModalDialogFlags`,
		QgsProviderRegistry::WidgetMode	widgetMode = `QgsProviderRegistry::WidgetMode::None`
	)

protected

Constructor.

Member Function Documentation

◆ addButton()

QPushButton* QgsAbstractDataSourceWidget::addButton ( ) const

inlineprotected

Returns the add Button.

Definition at line 143 of file qgsabstractdatasourcewidget.h.

◆ addButtonClicked

virtual void QgsAbstractDataSourceWidget::addButtonClicked ( )

inlinevirtualslot

Triggered when the add button is clicked, the add layer signal is emitted Concrete classes should implement the right behavior depending on the layer being added.

Definition at line 66 of file qgsabstractdatasourcewidget.h.

◆ addDatabaseLayers

void QgsAbstractDataSourceWidget::addDatabaseLayers	(	const QStringList &	paths,
		const QString &	providerKey
	)

signal

Emitted when a DB layer has been selected for addition.

◆ addMeshLayer

void QgsAbstractDataSourceWidget::addMeshLayer	(	const QString &	url,
		const QString &	baseName,
		const QString &	providerKey
	)

signal

Emitted when a mesh layer has been selected for addition.

Since: QGIS 3.4

◆ addRasterLayer

void QgsAbstractDataSourceWidget::addRasterLayer	(	const QString &	rasterLayerPath,
		const QString &	baseName,
		const QString &	providerKey
	)

signal

Emitted when a raster layer has been selected for addition.

◆ addVectorLayer

void QgsAbstractDataSourceWidget::addVectorLayer	(	const QString &	uri,
		const QString &	layerName,
		const QString &	providerKey = `QString()`
	)

signal

Emitted when a vector layer has been selected for addition.

If providerKey is not specified, the default provider key associated with the source will be used.

◆ addVectorLayers

void QgsAbstractDataSourceWidget::addVectorLayers	(	const QStringList &	layerList,
		const QString &	encoding,
		const QString &	dataSourceType
	)

signal

Emitted when one or more OGR supported layers are selected for addition.

Parameters

layerList	list of layers protocol URIs
encoding	encoding
dataSourceType	string (can be "file" or "database")

◆ connectionsChanged

void QgsAbstractDataSourceWidget::connectionsChanged ( )

signal

Emitted when the provider's connections have changed This signal is normally forwarded the app and used to refresh browser items.

◆ enableButtons

void QgsAbstractDataSourceWidget::enableButtons ( bool enable )

signal

Emitted when the ok/add buttons should be enabled/disabled.

◆ mapCanvas()

const QgsMapCanvas * QgsAbstractDataSourceWidget::mapCanvas ( ) const

protected

Returns the map canvas (can be null)

Definition at line 33 of file qgsabstractdatasourcewidget.cpp.

◆ progress

Q_DECL_DEPRECATED void QgsAbstractDataSourceWidget::progress	(	int	,
		int
	)

signal

Emitted when a progress dialog is shown by the provider dialog.

Deprecated:: Since QGIS 3.4 this signal is no longer used. Use QgsProxyProgressTask instead to show progress reports.

◆ progressMessage

void QgsAbstractDataSourceWidget::progressMessage ( QString message )

signal

Emitted when a progress dialog is shown by the provider dialog.

◆ refresh

virtual void QgsAbstractDataSourceWidget::refresh ( )

inlinevirtualslot

Triggered when the provider's connections need to be refreshed The default implementation does nothing.

Definition at line 59 of file qgsabstractdatasourcewidget.h.

◆ replaceVectorLayer

void QgsAbstractDataSourceWidget::replaceVectorLayer	(	const QString &	oldId,
		const QString &	source,
		const QString &	name,
		const QString &	provider
	)

signal

Emitted when a layer needs to be replaced.

Parameters

oldId	old layer ID
source	URI of the layer
name	of the layer
provider	key

◆ setMapCanvas()

void QgsAbstractDataSourceWidget::setMapCanvas ( const QgsMapCanvas * mapCanvas )

Store a pointer to the map canvas to retrieve extent and CRS Used to select an appropriate CRS and possibly to retrieve data only in the current extent.

Definition at line 59 of file qgsabstractdatasourcewidget.cpp.

◆ setupButtons()

void QgsAbstractDataSourceWidget::setupButtons ( QDialogButtonBox * buttonBox )

protected

Connect the ok and apply/add buttons to the slots.

Definition at line 38 of file qgsabstractdatasourcewidget.cpp.

◆ widgetMode()

QgsProviderRegistry::WidgetMode QgsAbstractDataSourceWidget::widgetMode ( ) const

protected

Returns the widget mode.
