Detailed Description
The QQuickTextureFactory class provides an interface for loading custom textures from QML.
The purpose of the texture factory is to provide a placeholder for a image data that can be converted into an OpenGL texture.
Creating a texture directly is not possible as there is rarely an OpenGL context available in the thread that is responsible for loading the image data.
Member Function Documentation
QQuickTextureFactory::QQuickTextureFactory()
Constructs a texture factory. Since QQuickTextureFactory is abstract, it cannot be instantiated directly.
[override virtual]
QQuickTextureFactory::~QQuickTextureFactory()
Destroys the texture factory.
[pure virtual]
QSGTexture *QQuickTextureFactory::createTexture(QQuickWindow *window) const

QImage QQuickTextureFactory::image() const
[pure virtual]
int QQuickTextureFactory::textureByteCount() const
[static]
QQuickTextureFactory *QQuickTextureFactory::textureFactoryForImage(const QImage &image)
Returns a QQuickTextureFactory holding the given image.
This is typically used as a helper in QQuickImageResponse::textureFactory.
This function was introduced in Qt 5.6.
