Class: QgsMapLayerProxyModel

class qgis.core.QgsMapLayerProxyModel(parent: QObject = None)

Bases: PyQt5.QtCore.QSortFilterProxyModel

QgsMapLayerProxModel creates a proxy model with a QgsMapLayerModel as source model. It can be used to filter the layers list in a widget.

The QgsMapLayerProxyModel class provides an easy to use model to display the list of layers in widgets.
