Detailed Description

Abstract base Data Source Widget to create connections and add layers This class provides common functionality and the interface for all source select dialogs used by data providers to configure data sources and add layers.

The implementation is generic enough to handle other layer search and selection widgets.

Since: QGIS 3.0

Definition at line 47 of file qgsabstractdatasourcewidget.h.

protected

Returns the associated browser model (may be nullptr).

Since: QGIS 3.18

Definition at line 33 of file qgsabstractdatasourcewidget.cpp.

◆ connectionsChanged

void QgsAbstractDataSourceWidget::pushMessage	(	const QString &	title,
		const QString &	message,
		const Qgis::MessageLevel	level = `Qgis::MessageLevel::Info`
	)

signal

Since: QGIS 3.14

◆ refresh

virtual void QgsAbstractDataSourceWidget::refresh ( )

inlinevirtualslot

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

Reimplemented in QgsOWSSourceSelect.

Definition at line 80 of file qgsabstractdatasourcewidget.h.
