我为没有得到这个而感到难过。
但是，尽管我读了几篇关于测量pass和排列pass的文章并编写了几个小程序，但我仍然很难做到这一点。
对我来说，任何用户控件都将具有“最小尺寸”（之后唯一可能的解决方案是将其作为整个位图缩小或添加滚动条）是有意义的。它还可以使用任何额外的屏幕空间。
椭圆没有最小尺寸，并且可以折叠到尺寸零。
因此，考虑一下这个示例，
<Grid>
<StackPanel Orientation="Horizontal" Height="20">
<Ellipse Fill="Blue"/>
<Ellipse Fill="Green"/>
<Ellipse Fill="BlueViolet"/>
</StackPanel>
</Grid>
要实现以下效果，需要添加的 xaml 代码最少是多少：
- 使它们强制使用统一 40 的“最小大小”。并统一动态调整大小。
- 让它们强制使用统一的 40 的“最小尺寸”。并动态地非均匀地调整大小（以便它们可以拉伸得很宽，但尺寸永远不会低于 40/40）。
- 让它们强制达到最小高度，但拉伸到可用宽度。
- 使它们均匀拉伸以适应堆栈面板的恒定高度。
- 使 stackpanel 拉伸以填充其容器的动态高度。
谢谢。
I feel bad about not getting this.
But, although I have read several articles on measure pass and arrange pass and written several small programs, I still have a hard time with this.
It makes sense to me that any user control will have a "minimum size" (after which only possible solution would be to shrink it as a whole bitmap wise or add a scroll bar). It will also have a way to use any additional screen real estate given to it.
Ellipses have no minimum size and can collapse to size zero.
So, consider this example
<Grid>
<StackPanel Orientation="Horizontal" Height="20">
<Ellipse Fill="Blue"/>
<Ellipse Fill="Green"/>
<Ellipse Fill="BlueViolet"/>
</StackPanel>
</Grid>
what is the least amount of xaml code needed to add to achieve the following effects:
- Make them force a "minimum size" of uniform 40. And dynamically resize uniformly.
- Make them force a "minimum size" of uniform 40. And dynamically resize non-uniformly (so that the they can stretch really wide, but will never size below 40/40).
- Make them force a minimum height, but stretch to available width.
- Make them stretch uniformly fitting a constant height of the stackpanel.
- Make the stackpanel stretch to fill the dynamic height of its container.
Thank you.

在大多数情况下，您可能想要使用
UniformGrid使用一列而不是StackPanel。要强制大小，请使用Style设置MinHeight和MinWidth。如果保证一致性是“单向”的，您只需绑定宽度到实际高度。In most of those cases you probably want to use a
UniformGridwith one column instead of aStackPanel. To force sizes use aStylewhich sets theMinHeightandMinWidth. If the uniformity is guaranteed to be "one-way" you can just bind theWidthto theActualHeight.
