/**
 * @brief A widget that visually represents the status of a Task
 *
 * The TaskViewItem widget shows a description of the Task (Task::text(), a progress bar (updated by
 * Task::ProgressChanged), the Task's status (text generated from Task::status() or Task::error()), and provides
 * a cancel button (triggering Task::Cancel()) for cancelling a Task before it finishes.
 *
 * The main entry point is SetTask() after a Task and TaskViewItem objects are created.
