    SetTargetImage(new_task);
    currentTask = new_task;
    progressBar.ResetProgress();
}

NextScene()

void Gui::NextScene ( Scene  next )

virtual

Handles the next scene from the video processing pipeline. If the result is empty, the viewing pane is updated, otherwise, the progress bar is updated.
