如何在Qt中显示或创建360转盘？
[英]How to show or create a 360 Rotating dial in Qt?
问题描述
Are there any Widget in Qt by which a 360 rotating dial can be displayed? 
Qt是否有可显示360度旋转刻度盘的Widget ？ I want to show just like below. 我想显示如下。 But there would be a indicator. 但是会有一个指标。 If the user rotate this indicator, current angular position of indicator in degree will be displayed in a QLineEdit . 如果用户旋转该指示器， QLineEdit度为单位的指示器的当前角度位置将显示在QLineEdit 。 I have already searched by using QDial , but unfortunately didn't get any function for this. 我已经使用QDial进行了搜索，但是不幸的是没有得到任何功能。
I would appreciate any help. 我将不胜感激任何帮助。 Thanks in advance. 提前致谢。

Qt's QDial is merely a wrapper around a platform-dependend fancy dial. Qt的QDial只是围绕平台依赖的精美表盘的包装。
Try QwtDial from the Qwt library at http://qwt.sourceforge.net/ for more control over the appearance and behaviour. 从http://qwt.sourceforge.net/的Qwt库尝试QwtDial ，以更好地控制外观和行为。
