The purpose of an image response is to provide a way for image provider jobs to be executed in an asynchronous way.
See the Image Response Provider Example for a complete implementation.
See also QQuickImageProvider.
Member Function Documentation
Constructs the image response
Destructs the image response
This method is used to communicate that the response is no longer required by the engine.
It may be reimplemented to cancel a request in the provider side, however, it is not mandatory.
[virtual] QString QQuickImageResponse::errorString() const
Returns the error string for the job execution. An empty string means no error.
Signals that the job execution has finished (be it successfully, because an error happened or because it was cancelled).
[pure virtual] QQuickTextureFactory *QQuickImageResponse::textureFactory() const
Note: This method will be called only when needed. For example, it may not be called if there is an error or the job is cancelled. Therefore, allocate the QQuickTextureFactory instance only in this method or otherwise ensure its deletion.
