详细描述

QSGFlatColorMaterial class provides a convenient way of rendering solid colored geometry in the scene graph.

警告: This utility class is only functional when running with the OpenGL backend of the Qt Quick scenegraph.

The flat color material will fill every pixel in a geometry using a solid color. The color can contain transparency.

The geometry to be rendered with a flat color material requires vertices in attribute location 0 in the QSGGeometry object to render correctly. The QSGGeometry::defaultAttributes_Point2D () returns an attribute set compatible with this material.

The flat color material respects both current opacity and current matrix when updating its rendering state.
