QmlTextureLayer

Composes borrowed QmlViews into an application-owned OpenGL panel.

QWidget* rootWidget() const
void setRootWidget(QWidget* root)
bool synchronize(): Adopts current-page views without recreating their QML scenes.
quint64 requiredBytes(const QRectF& source, qreal devicePixelRatio) const: Conservative target bytes for source, or maximum quint64 if unsupported. Source is the panel rectangle in root-widget coordinates; DPR is in (0, 4].
bool prepareFrame(QOpenGLContext* context, const QRectF& source, qreal devicePixelRatio, quint64 maximumBytes): Renders dirty visible scenes within the aggregate byte limit.
unsigned int compose(unsigned int baseTexture, const QSize& pixels, quint64 baseRevision): Composes over a borrowed bottom-up RGBA texture; zero means failure. The result is borrowed and expires on resize, context loss or cache release.
unsigned int textureId() const
QSize textureSize() const
QVariantMap statistics() const
void clearFrameCaches(): Releases GPU caches while retaining scene delegation and local state.
void release(): Restores native Quick widgets after the caller removes capture effects.
