Detailed Description▲
Member Function Documentation▲
[static, since 6.0] QSGTexture *QSGOpenGLTexture::fromNative(GLuint textureId, QQuickWindow *window, const QSize &size, QQuickWindow::CreateTextureOptions options = {})▲
Creates a new QSGTexture wrapping an existing OpenGL texture object for window.
The native object specified in textureId is wrapped, but not owned, by the resulting QSGTexture. The caller of the function is responsible for deleting the returned QSGTexture, but that will not destroy the underlying native object.
This function is currently suitable for 2D RGBA textures only.
This function will return null if the scenegraph has not yet been initialized.
Use options to customize the texture attributes. Only the TextureHasAlphaChannel and TextureHasMipmaps are taken into account here.
size specifies the size in pixels.
This function must be called on the scenegraph rendering thread.
This function was introduced in Qt 6.0.

[static, since 6.1] QSGTexture *QSGOpenGLTexture::fromNativeExternalOES(GLuint textureId, QQuickWindow *window, const QSize &size, QQuickWindow::CreateTextureOptions options = {})▲
Creates a new QSGTexture wrapping an existing OpenGL ES texture object for window.
The native object specified in textureId is wrapped, but not owned, by the resulting QSGTexture. The caller of the function is responsible for deleting the returned QSGTexture, but that will not destroy the underlying native object.
This function is suitable only for textures that are meant to be used with the GL_TEXTURE_EXTERNAL_OES target: usually textures to which another device (such as a camera) writes data.
This function will return null if the scenegraph has not yet been initialized.
Use options to customize the texture attributes. Only the TextureHasAlphaChannel and TextureHasMipmaps are taken into account here.
size specifies the size in pixels.
This function must be called on the scenegraph rendering thread.
This function was introduced in Qt 6.1.
