- InputEventArgs
The input event data to compare this gesture to.
Returns
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.
