为什么我要在ContentControl上将IsTabStop设置为true？

是正确 ContentControl 从 Control 只是继承了 IsTabStop 的默认值>。也没有理由认为 true 对于 ContentControl 的有效性比对 Control 。

例如，你可能有一个控件，它的内容应该是图形的，例如 Shape 元素或者图片。但是，当用户按下特定的按键时，您的控件可能会对内容执行某些操作。

Given the following:

• setting IsTabStop to false on a ContentControl will not prevent its content from acting as a tab-stop
• setting IsTabStop to true will result in an invisible tab-stop, which does nothing, in your application

I have the following two questions:

Douglas is correct ContentControl simply inherits the default value of IsTabStop from Control. Also there is no good reason to assume that the value of true is less valid for a ContentControl than it is for Control.

For example, you might have a control that expects its content be something graphical such a set of Shape elements or an Image. However your control may perform certain operations on the content when the user presses specific keys.
