声明方式:
声明
[DllImportAttribute("user32.dll")]
private static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags);
参数说明:
Code
(1). IntPtr hwnd: 目标窗口的句柄对象, 一般为 this.Handle
(2). int dwTime: 动画的持续时间, 数值越大动画效果的时间越长
(3). int dwFlags: 动画效果类型选项, 在C#中声明如下:
注: 您程序中只声明需要的动画类型即可, 关于每个参数的含义会在后面详细说明
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;
动画效果类型详细说明表:
1. AW_SLIDE : 使用滑动类型, 默认为该类型. 当使用 AW_CENTER 效果时, 此效果被忽略
2. AW_ACTIVE: 激活窗口, 在使用了 AW_HIDE 效果时不可使用此效果
3. AW_BLEND: 使用淡入效果
4. AW_HIDE: 隐藏窗口
5. AW_CENTER: 与 AW_HIDE 效果配合使用则效果为窗口几内重叠, 单独使用窗口向外扩展.
6. AW_HOR_POSITIVE : 自左向右显示窗口
7. AW_HOR_NEGATIVE: 自右向左显示窗口
8. AW_VER_POSITVE: 自顶向下显示窗口
9. AW_VER_NEGATIVE : 自下向上显示窗口
看懂了这些, 下面我们的工作会变得非常简单.
启动程序后, 动画效果显示窗口的代码如下:
Code
AnimateWindow(this.Handle, 1000, AW_SLIDE + AW_CENTER);
而关闭程序后, 动画效果显示窗口代码如下:
Code
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
AnimateWindow(this.Handle, 500, AW_SLIDE + AW_VER_POSITIVE + AW_HIDE);
}
