Detailed Description

A model for showing available data sources and other items in a structured tree.

QgsBrowserGuiModel is the foundation for the QGIS browser panel, and includes items for the different data providers and folders accessible to users.

Since: QGIS 3.10

Constructor & Destructor Documentation

◆ QgsBrowserGuiModel()

QgsBrowserGuiModel::QgsBrowserGuiModel ( QObject * parent = nullptr )

explicit

Constructor for QgsBrowserGuiModel, with the specified parent object.

Note: QgsBrowserModel models are not initially populated and use a deferred initialization approach. After constructing a QgsBrowserModel, a call must be made to initialize() in order to populate the model.
