WPF/Windows 7:禁用默认进度栏辉光动画

Question

快速WPF问题 - 在WPF上的Win 7(我假设Vista),默认进度条做了一个漂亮的小发光"飞快移动"-y动画.

我在一个屏幕上显示了大约48个内容的进度,并且让所有这些东西都在你身上who - - - 你能禁用这些动画而不影响应用程序中的其他默认动画吗？

Answer 1

罗伯特的答案很强大.这是一个hack(因为它依赖于执行发光的元素的内部名称,这是一个实现细节,可能在后续版本中更改):

void SetGlowVisibility(ProgressBar progressBar, Visibility visibility) {
    var glow = progressBar.Template.FindName("PART_GlowRect", progressBar) as FrameworkElement;
    if (glow != null) glow.Visibility = visibility;
}

如果进度条的实现方式发生变化,这个黑客可能会停止工作.

另一方面,完全取代XAML和样式的解决方案可以锁定并修复颜色,边框等,并禁用将来可能添加到更新版本的ProgressBar的行为...

Answer 2

简单的非动画进度条可以写成带有两个填充矩形的网格:左边的一个用绿色填充,右边用灰色填充.

Grid将有两个列定义.

改变两者的宽度会影响进度的变化.

Answer 3

我同意马修的评论，但无论如何，您的答案是应用没有动画的自定义样式。这是原始样式（通过反射器），您可以删除/调整/任何内容：

和转换器类：
