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.

Definition at line 45 of file qgsabstractdatasourcewidget.h.

Constructor & Destructor Documentation

Member Function Documentation

◆ addButton()

QPushButton * QgsAbstractDataSourceWidget::addButton ( ) const
inlineprotected

Returns the add Button.

Definition at line 231 of file qgsabstractdatasourcewidget.h.

◆ addButtonClicked

void QgsAbstractDataSourceWidget::addButtonClicked ( )
virtualslot

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 61 of file qgsabstractdatasourcewidget.cpp.

◆ addDatabaseLayers

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

void QgsAbstractDataSourceWidget::addLayer ( Qgis::LayerType  type,
const QString &  url,

)
signal

Emitted when a layer has been selected for addition.

This is a generic method, intended for replacing the specific layer type signals implemented above.

Warning
For QGIS versions < 4.x, the specific layer type added signals must be emitted for vector, raster, mesh, vector tile and point cloud layers in addition to this signal.
Since
QGIS 3.34

Note
Not all data providers may be able to configure the widget from the provided uri, in that case this method returns false.
Since
