WPF Rectangle does not have a Click event
提问by M. Dudley
回答by Kent Boogaart
If you're not happy with MouseDownand MouseUp, perhaps you could just put the Rectanglein a Buttonand handle the Button's Clickevent?
如果您对MouseDownand不满意MouseUp，也许您可以将Rectanglea放入aButton并处理Button'sClick事件？
<Button>
<Button.Template>
<ControlTemplate>
<Rectangle .../>
</ControlTemplate>
</Button.Template>
</Button>
It really depends with the behavior you're after. Please elaborate if needs be.
这真的取决于你所追求的行为。如果需要，请详细说明。

To add click handing to a Rectangle itself, you can use the InputBindingsproperty:
要将单击处理添加到 Rectangle 本身，您可以使用InputBindings属性：
<Rectangle Fill="Blue" Stroke="Black">
<Rectangle.InputBindings>
<MouseBinding Gesture="LeftClick" Command="{Binding FooCommand}"/>
</Rectangle.InputBindings>
</Rectangle>
This will cause the FooCommand to be executed when the rectangle is clicked. Handy if you're using MVVM!
这将导致在单击矩形时执行 FooCommand。如果您使用的是 MVVM，则非常方便！

I was looking for the related DoubleClick event and came across this suggestionto simply embed the object of interest in a ContentControl.
我正在寻找相关的 DoubleClick 事件并遇到了这个建议，即简单地将感兴趣的对象嵌入到 ContentControl 中。
Here is their example (with a border, which also did not support click/double click).
这是他们的示例（带有边框，也不支持单击/双击）。
<ContentControl MouseDoubleClick="OnDoubleClick">
<Border Margin="10" BorderBrush="Black" BorderThickness="2">
<Grid Margin="4">
<Rectangle Fill="Red" />
<TextBlock Text="Hello" FontSize="15" />
</Grid>
</Border>
</ContentControl>
