看起来 MahApps.Metro ProgressRing 控件默认为 60x60 的最小尺寸。
ProgressRing 有一个名为“IsLarge”的属性,但即使将其设置为“False”,它似乎也无法使 ProgressRing 小于 60x60。
显然更改 Height 和 Width 属性也不会影响这一点。
将 GitHUb 视为 ProgressRing 的实际 c# 代码,看起来有几个属性会影响椭圆直径等,但这些属性是私有属性,无法从外部调用设置。
我怎样才能让这个更小?说 20x20 还是 30x30?
在下面的代码中,我指定 IsLarge=False,并将大小设置为 30x30,但仍默认为 60x60。
