这篇文章主要介绍了wxPython实现带颜色的进度条，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了wxPython实现带颜色进度条的具体代码，供大家参考，具体内容如下
【问题描述】
1、在使用wxpython创建进度条时遇到如下问题，使用SetForegroundColour和SetBackgrounColour指令在Win7下不生效，即无法改变进度条的颜色及其背景颜色。
2、查阅资料发现wx.lib.agw.pygauge可以实现进度条颜色的修改（具体指令请参考pygauge说明文档），但其显示效果为平面较差（如下图）：
图1-1 pygauge制作的进度条
期望实现的进度条效果如下：
图1-2 期望效果图
