C#模擬MSN窗體抖動
窗體抖動是件很有意思的事情,就讓我們看看一起來看看它的原理吧。
其實(shí)是生成隨機(jī)數(shù),然后改變Form的左上角的坐標(biāo)。
我用的是循環(huán)來弄得,其實(shí)可以用timer來控制.
我把抖動分成了兩種抖動:
1。 生成隨機(jī)數(shù),改變窗體左上角坐標(biāo),然后立即把窗體的坐上角坐標(biāo)還原,繼續(xù)循環(huán)。
2。 生成隨機(jī)數(shù),改變窗體左上角坐標(biāo),循環(huán)完畢之后,然后立即把窗體的坐上角坐標(biāo)還原。
核心代碼如下:
//第一種抖動
PRivate void button1_Click(object sender, EventArgs e)
{
int recordx = this.Left; //保存原來窗體的左上角的x坐標(biāo)
int recordy = this.Top; //保存原來窗體的左上角的y坐標(biāo)
Random random = new Random();
for (int i = 0; i < 100; i++)
{
int x = random.Next(rand);
int y = random.Next(rand);
if (x % 2 == 0)
{
this.Left = this.Left + x;
}
else
{
this.Left = this.Left - x;
}
if (y % 2 == 0)
{
this.Top = this.Top + y;
}
else
{
this.Top = this.Top - y;
}
this.Left = recordx; //還原原始窗體的左上角的x坐標(biāo)
this.Top = recordy; //還原原始窗體的左上角的y坐標(biāo)
}
}
//第二種抖動
private void button2_Click(object sender, EventArgs e)
{
int recordx = this.Left;
int recordy = this.Top;
Random random = new Random();
for (int i = 0; i < 50; i++)
{
int x = random.Next(rand);
int y = random.Next(rand);
if (x % 2 == 0)
{
this.Left = this.Left + x;
}
else
{
this.Left = this.Left - x;
}
if (y % 2 == 0)
{
this.Top = this.Top + y;
}
else
{
this.Top = this.Top - y;
}
System.Threading.Thread.Sleep(1);
}
this.Left = recordx;
this.Top = recordy;
}
