Detailed Description

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

\inmodule QtQuick

Warning

This utility class is only functional when running with the default 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.
