Using previously indtroduced Tween

In my previous post I introduced a Tween class, which lets you to manipulate object Properties in timely manner.
Let's consider we have a simple button on client area, which has "btnButton" name. The following code will change the button's width from 50 to 300 pixels in 3 seconds (3000 milliseconds).

    Tween tmpTween = new Tween();
    tmpTween.MaxValue = 300;
    tmpTween.MinValue = 50;
    tmpTween.Period = 10000;
    tmpTween.Target = this.btnTest;
    tmpTween.Property = "Height";
    tmpTween.Start();
