Detailed Description

A widget drawing a rotating spinner to indicate an ongoing operation.

Usage:

• Pass the widget where the spinner shall be shown as the parent widget to the constructor. Important: Do NOT change the parent afterwards!
• Call either show(), hide() or setVisible() to make the spinner visible or not.
• Do not set a widget size or position manually, this is controlled by the widget itself.

Memory management is done by the Qt parent-child mechanism.
