示例

以下示例演示如何获取具有鼠标捕获的 元素。

// Mouse.Capture returns an IInputElement.
IInputElement captureElement;

captureElement = Mouse.Captured;

// Update the Label that displays the element with mouse capture.
lblHasMouseCapture.Content = captureElement.ToString();

' Mouse.Capture returns an IInputElement.
Dim captureElement As IInputElement

captureElement = Mouse.Captured

' Update the Label that displays the element with mouse capture.
lblHasMouseCapture.Content = CType(captureElement, Object).ToString()

注解

当元素捕获鼠标时，无论光标是否在其边框内，它都会接收鼠标输入。 通常仅在拖放操作期间以这种方式捕获鼠标，并保留捕获，直到拖放操作的放置操作发生。
