这里主要利用API函数Animate Window实现窗体左右,上下,扩展,淡入滑动或滚动动画效果,步骤如下:

1.新建窗体,使用2个GroupBox控件。

2.在控件1中添加2个RadioButton控件,并设置Text分别为“滚动窗体”,“滑动窗体”,并使前者Checked设置为True。

3.在空间2中添加6个按钮,Text分别为“自左向右动画”,“自右向左动画”,“自上向下动画”,“自下向上动画”,“向外扩展动画”,“淡入动画窗体”。

4.添加一新的Window窗体,设置Text为“动画窗体”。设置其“BackgroundImage”属性,导入一张要加载的图像,然后设置其“BackgroundImageLayout”属性为“Stretch”。

5.各按钮事件主要代码如下:

复制代码 代码如下:

private void button1_Click(object sender, EventArgs e)

{

Form2 myf = new Form2();

if (radioButton1.Checked == true)

{

myf.Text = "自左向右滚动窗体动画效果";

}

else

{

myf.Text = "自左向右滑动窗体动画效果";

}

myf.Show();

}

private void button4_Click(object sender, EventArgs e)

{

Form2 myf = new Form2();

if (radioButton1.Checked == true)

{

myf.Text = "自右向左滚动窗体动画效果";

}

else

{

myf.Text = "自右向左滑动窗体动画效果";

}

myf.Show();

}

private void button2_Click(object sender, EventArgs e)

{

Form2 myf = new Form2();

if (radioButton1.Checked == true)

{

myf.Text = "自上向下滚动窗体动画效果";

}

else

{

myf.Text = "自上向下滑动窗体动画效果";

}

myf.Show();

}

private void button5_Click(object sender, EventArgs e)

{

Form2 myf = new Form2();

if (radioButton1.Checked == true)

{

myf.Text = "自下向上滚动窗体动画效果";

}

else

{

myf.Text = "自下向上滑动窗体动画效果";

}

myf.Show();

}

private void button3_Click(object sender, EventArgs e)

{

Form2 myf = new Form2();

myf.Text = "向外扩展窗体动画效果";

myf.Show();

}

private void button6_Click(object sender, EventArgs e)

{

Form2 myf = new Form2();

myf.Text = "淡入窗体动画效果";

myf.Show();

}

6.双击Form2窗体,进入代码视图。首先定义公用变量,具体代码如下:

复制代码 代码如下:

public const Int32 AW_HOR_POSITIVE = 0X00000001;

public const Int32 AW_HOR_NEGATIVE = 0X00000002;

public const Int32 AW_VER_POSITIVE = 0X00000004;

public const Int32 AW_VER_NEGATIVE = 0X00000008;

public const Int32 AW_CENTER = 0X00000010;

public const Int32 AW_HIDE = 0X00010000;

public const Int32 AW_ACTIVATE = 0X00020000;

public const Int32 AW_SLIDE = 0X00040000;

public const Int32 AW_BLEND = 0X00080000;

[System.Runtime.InteropServices.DllImportAttribute("user32.dll")]

private static extern bool AnimateWindow(IntPtr hwnd,int dwTime,int dwFlags);

7.下面为Form2窗体添加加载事件代码,具体如下:

复制代码 代码如下:

private void Form2_Load(object sender, EventArgs e)

{

if (this.Text == "自左向右滚动窗体动画效果")

{

AnimateWindow(this.Handle,2000,AW_HOR_POSITIVE);

}

if (this.Text == "自左向右滑动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_SLIDE+AW_HOR_POSITIVE);

}

if (this.Text == "自右向左滚动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_HOR_NEGATIVE);

}

if (this.Text == "自右向左滑动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_SLIDE + AW_HOR_NEGATIVE);

}

if (this.Text == "自上向下滚动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_VER_POSITIVE);

}

if (this.Text == "自上向下滑动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_SLIDE + AW_VER_POSITIVE);

}

if (this.Text == "自下向上滚动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_VER_NEGATIVE);

}

if (this.Text == "自下向上滑动窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_SLIDE + AW_VER_NEGATIVE);

}

if (this.Text == "向外扩展窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_SLIDE + AW_CENTER);

}

if (this.Text == "淡入窗体动画效果")

{

AnimateWindow(this.Handle, 2000, AW_BLEND);

}
