特殊类型窗体制作: 制作可以飘动的窗体

原理: (这里演示纵坐标不变的窗体移动), 两个 timer, 一个控制从左至右, 到达预先设定的点时触发另一个 timer,

当然另一个 timer 控制从右至左的移动( 其实质是横坐标的变化)

如果你希望上下左右或斜线移动甚至乱七八糟(呵呵, 应该叫随机)只要加足够的 timer 并控制好横纵坐标的变换即可.

{
//窗体的左上角横坐标随着timer1不断加一
Point p = new Point(this.DesktopLocation.X + 1, this.DesktopLocation.Y);
this.DesktopLocation = p;
if (p.X == 630)
{
timer1.Enabled = false;
timer2.Enabled = true;
}
}

private void timer2_Tick(object sender, EventArgs e)
{
//窗体的左上角横坐标随着timer2不断减一
Point p = new Point(this.DesktopLocation.X - 1, this.DesktopLocation.Y);
this.DesktopLocation = p;
if (p.X == 20)
{
timer1.Enabled = true;
timer2.Enabled = false;
}
}

private void button1_Click(object sender, EventArgs e)
{
timer1.Stop();
timer2.Stop();
}
