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.

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.

Definition at line 22 of file qgsbrowserguimodel.cpp.
