详细描述

The QPickTriangleEvent class holds information when a triangle is picked.

When QPickingSettings::pickMode() is set to QPickingSettings::TrianglePicking , the signals on QObjectPicker will carry an instance of QPickTriangleEvent .

This contains the details of the triangle that was picked.

注意: In the case of indexed rendering, the point indices are relative to the array of coordinates, not the array of indices.
