问题描述
我正在尝试计算与WPF Scrollbar thumb元素的大小相关的算法.
I am attempting to work out the algorithm associated with sizing of the WPF Scrollbar thumb element.
可以使用Scrollbar.ViewportSize属性调整thumb元素的大小，但它又与Scrollbar.Minimum和Scrollbar.Maximum值相关.
The thumb element can be sized using the Scrollbar.ViewportSize property, but it in turn is related to the Scrollbar.Minimum and Scrollbar.Maximum values.
到目前为止，我发现的是:
What I have discovered so far is:
对于最小和最大 0 和 10 ，视口大小为:
For a Minimum and Maximum of 0 and 10, a ViewportSize of:
0-拇指的最小大小
5-拇指大约占可用曲目的25％
10-拇指大约占可用曲目的50％
100-略过可用曲目的75％
1000-拇指大约占可用曲目的90％
10000-拇指会填充可用的曲目.
0 - Thumb minimum size
5 - Thumb approximately 25% of the available track
10 - Thumb approximately 50% of the available track
100 - Thumb approximately 75% of the available track
1000 - Thumb approximately 90% of the available track
10000 - Thumb fills the available track.
[注意:这些数字仅来自于我的反复试验！]
[note: these figures are only from my rough trial and error!]
理想情况下，我希望能够有一个算法，其中给定滚动条的最小值和最大值，我可以将拇指大小设置为恰好是可用轨道的x％.
Ideally I'd like to be able to have an algorithm where given the minimum and maximum values for the Scrollbar I can set the thumb size to be exactly x% of the available track.
任何人都可以帮忙吗?
谢谢.

您可能已经发现了这个问题，但是以为我可以发帖，以防其他人到此结束.
You've prob found this already but thought I'd post in case others end up here.
