Detailed Description

The QgsDataSourceSelectWidget class embeds the browser view to select an existing data source.

By default any layer type can be chosen, the valid layer type can be restricted by setting a layer type filter with setLayerTypeFilter(layerType) or by activating the filter directly from the constructor.

To retrieve the selected data source, uri() can be called and it will return a (possibly invalid) QgsMimeDataUtils::Uri.

Constructor & Destructor Documentation

◆ QgsDataSourceSelectWidget()

QgsDataSourceSelectWidget::QgsDataSourceSelectWidget	(	QgsBrowserGuiModel *	browserModel = `nullptr`,
		bool	setFilterByLayerType = `false`,
		Qgis::LayerType	layerType = `Qgis::LayerType::Vector`,
		QWidget *	parent = `nullptr`
	)

Constructs a QgsDataSourceSelectWidget, optionally filtering by layer type.

Parameters

browserModel	an existing browser model (typically from app), if `nullptr` an instance will be created
setFilterByLayerType	activates filtering by layer type
layerType	sets the layer type filter, this is in effect only if filtering by layer type is also active
parent	the object
