问题描述
我在我的应用程序中使用了一个不确定的进度条，我得到了一系列水平运行的块的糟糕动画.没有像vista或windows 7这样的更好的样式吗?
I'm using an indeterminate progressbar in my application and I get this bad animation of a series of blocks running horizontally. Isn't there a better style available like vista or windows 7?
推荐答案
您的进度条具有与您当前的 Windows 主题相对应的样式.如果您在带有 Aero 主题的 Windows 7 上运行您的应用程序，您的进度条将相应显示.
Your progress bar has a style that corresponds to your current windows theme. If you run your application on Windows 7 with an Aero theme your progress bar will look accordingly.
如果您希望它看起来始终相同(无论选择什么 Windows 主题)，您都需要为进度条定义自己的样式.
If you want it to look always the same (no matter what windows theme is selected) you will need to define your own style for the progress bar.
这是来自 Aero Normal Color 主题的样式:
Here is the style from the Aero Normal Color theme:

将此代码放在应用程序中的 Themes/Generic.xaml 文件中，您的进度条将始终采用这种样式.
Put this code in the Themes/Generic.xaml file in your application and your progress bars will always have this style.
