MouseGesture.Matches(Object, InputEventArgs) 方法

定义

命名空间:

System.Windows.Input

程序集:

PresentationCore.dll

确定 MouseGesture 是否和与指定 InputEventArgs 对象关联的输入匹配。

public:
 override bool Matches(System::Object ^ targetElement, System::Windows::Input::InputEventArgs ^ inputEventArgs);

public override bool Matches (object targetElement, System.Windows.Input.InputEventArgs inputEventArgs);

override this.Matches : obj * System.Windows.Input.InputEventArgs -> bool

Public Overrides Function Matches (targetElement As Object, inputEventArgs As InputEventArgs) As Boolean

参数

targetElement

Object

目标。

inputEventArgs

InputEventArgs

要与此笔势进行比较的输入事件数据。

返回

Boolean

如果事件数据与此 MouseGesture 匹配，则为 true；否则为 false。

示例

以下示例演示如何测试 是否 MouseGesture 与 与 实例 InputEventArgs关联的输入匹配。 事件处理程序MouseDown使用 Matches 方法将事件数据与 MouseGesture 进行比较。

private void OnMouseDown(object sender, MouseEventArgs e)
{
    MouseGesture mouseGesture = new MouseGesture(MouseAction.MiddleClick,ModifierKeys.Control);

    if (mouseGesture.Matches(null, e))
    {
        MessageBox.Show("Trapped Mouse Gesture");
    }
}

Private Overloads Sub OnMouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)
    Dim mouseGesture As New MouseGesture(MouseAction.MiddleClick,ModifierKeys.Control)

    If mouseGesture.Matches(Nothing, e) Then
        MessageBox.Show("Trapped Mouse Gesture")
    End If
End Sub
