createShader()

QSGMaterialShader * QSGHiQSubPixelDistanceFieldTextMaterial::createShader ( QSGRendererInterface::RenderMode renderMode ) const

overridevirtual

This function returns a new instance of a the QSGMaterialShader implementation used to render geometry for a specific implementation of QSGMaterial.

The function will be called only once for each combination of material type and renderMode and will be cached internally.

For most materials, the renderMode can be ignored. A few materials may need custom handling for specific render modes. For instance if the material implements antialiasing in a way that needs to account for perspective transformations when RenderMode3D is in use.

Reimplemented from QSGDistanceFieldTextMaterial.

type()

QSGMaterialType * QSGHiQSubPixelDistanceFieldTextMaterial::type ( ) const

overridevirtual

This function is called by the scene graph to query an identifier that is unique to the QSGMaterialShader instantiated by createShader().

For many materials, the typical approach will be to return a pointer to a static, and so globally available, QSGMaterialType instance. The QSGMaterialType is an opaque object. Its purpose is only to serve as a type-safe, simple way to generate unique material identifiers.

QSGMaterialType *type() const override
{
    static QSGMaterialType type;
    return &type;
}
