UIElement.ReleaseMouseCapture Method ()
.NET Framework (current version)
Releases the mouse capture, if this element held the capture.
Assembly: PresentationCore (in PresentationCore.dll)
If this element did not hold the capture, calling this method has no effect. Consider checking the value of IsMouseCaptured before you call this method.
The following example is the parallel to the example given for CaptureMouse: it handles mouse button up to release mouse capture and re-enable moving the mouse.
Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseButtonEventArgs) If Not Enabled Then Return End If e.Handled = True If Keyboard.IsKeyDown(Key.F1) = True Then Reset() Return End If Dim el As UIElement = CType(sender, UIElement) _point = e.MouseDevice.GetPosition(el) ' Initialize the center of rotation to the lookatpoint If Not _centered Then Dim camera As ProjectionCamera = CType(_slaves(0).Camera, ProjectionCamera) _center = camera.LookDirection _centered = True End If _scaling = (e.MiddleButton = MouseButtonState.Pressed) If Keyboard.IsKeyDown(Key.Space) = False Then _rotating = True Else _rotating = False End If el.CaptureMouse() End Sub Private Sub MouseUpHandler(ByVal sender As Object, ByVal e As MouseButtonEventArgs) If Not _enabled Then Return End If e.Handled = True ' Stuff the current initial + delta into initial so when we next move we ' start at the right place. If _rotating = True Then _rotation = _rotationDelta * _rotation Else _translate += _translateDelta _translateDelta.X = 0 _translateDelta.Y = 0 End If '_scale = _scaleDelta * _scale Dim el As UIElement = CType(sender, UIElement) el.ReleaseMouseCapture() End Sub
