Detailed Description

This widget is used to show the attributes of a set of features of a QgsVectorLayer.

The attributes can be edited. It supports two different layouts: the table layout, in which the attributes for the features are shown in a table and the editor layout, where the features are shown as a selectable list and the attributes for the currently selected feature are shown in a form.
