Примеры

В следующем примере показан обработчик событий мыши, который определяет, какие кнопки нажаты в данный момент, проверив состояние каждой кнопки мыши.

private void MouseDownHandler(object sender, MouseEventArgs e)
{
    if (e.RightButton == MouseButtonState.Pressed)
    {
        MessageBox.Show("The Right Mouse Button is pressed");
    }

    if (e.LeftButton == MouseButtonState.Pressed)
    {
        MessageBox.Show("The Left Mouse Button is pressed");
    }

    if (e.MiddleButton == MouseButtonState.Pressed)
    {

        MessageBox.Show("The Middle Mouse Button is pressed");
    }

    if (e.XButton1 == MouseButtonState.Pressed)
    {
        MessageBox.Show("The XButton1 Mouse Button is pressed");
    }

    if (e.XButton2 == MouseButtonState.Pressed)
    {
        MessageBox.Show("The XButton2 Mouse Button is pressed");
    }
}

Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseEventArgs)
    If e.RightButton = MouseButtonState.Pressed Then
        MessageBox.Show("The Right Mouse Button is pressed")
    End If

    If e.LeftButton = MouseButtonState.Pressed Then
        MessageBox.Show("The Left Mouse Button is pressed")
    End If

    If e.MiddleButton = MouseButtonState.Pressed Then

        MessageBox.Show("The Middle Mouse Button is pressed")
    End If

    If e.XButton1 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton1 Mouse Button is pressed")
    End If

    If e.XButton2 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton2 Mouse Button is pressed")
