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

Parameters

targetElement: Object

The target.

inputEventArgs: InputEventArgs

The input event data to compare this gesture to.

Returns

Boolean

true if the event data matches this KeyGesture; otherwise, false.

Examples

The following example shows how to test whether a KeyGesture matches the input associated with an instance of an InputEventArgs. A KeyDown event handler is created that compares the event data with the KeyGesture by using the Matches method.

private void OnKeyDown(object sender, KeyEventArgs e)
{
    KeyGesture keyGesture = new KeyGesture(Key.B, ModifierKeys.Control);

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

Private Overloads Sub OnKeyDown(ByVal sender As Object, ByVal e As KeyEventArgs)
    Dim keyGesture As New KeyGesture(Key.B, ModifierKeys.Control)

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

Remarks

targetElement can be used to make a more specific decision on whether a command should be invoked on a specific element.
