Windows界面编程第六篇动画启动效果（动画效果显示及隐藏窗口）

动画效果显示及隐藏窗口及大大美化程序界面，像QQ的登录窗口也是使用了动画效果显示及隐藏窗口。

本篇《Windows界面编程第六篇动画启动效果（动画效果显示及隐藏窗口）》就来介绍下如何使用动画效果来显示隐藏窗口。为了方便代码复用，本人已经将其封装成一个窗口动画效果类，先来看看这个窗口动画效果类的实现吧。

CAnimateWindow::CAnimateWindow(HWND hwnd)
{
	m_hwndWindow = hwnd;

void CAnimateWindow::SetWindowHwnd(HWND hwnd)
{
	m_hwndWindow = hwnd;
}

HWND CAnimateWindow::GetWindowHwnd()

	dwFlags = bShow ? AW_ACTIVATE : AW_HIDE;
	dwFlags |= bSlide ? AW_SLIDE : AW_BLEND;

	return ::AnimateWindow(m_hwndWindow, dwTime, dwFlags);
}

int CAnimateWindow::GetRandomNumber()
{
	srand((UINT)time(NULL));
	return rand() % 3;
}

代码非常简单，主要使用的是AnimateWindow函数。这个函数的函数原型如下：

BOOLAnimateWindow(

HWNDhwnd,

DWORDdwTime,

DWORDdwFlags

);

这个函数也极其简单，三个参数，一个表示窗口句柄，一个表示动画持续时间（毫秒），最后一个参数表示动画效果。可以有以下参数：

AW_SLIDE

Uses slide animation. By default, roll animation is used. This flag is ignored when used with AW_CENTER.

AW_ACTIVATE

Activates the window. Do not use this value with AW_HIDE.

AW_BLEND

Uses a fade effect. This flag can be used only if hwnd is a top-level window.

AW_HIDE

Hides the window. By default, the window is shown.

AW_CENTER

Makes the window appear to collapse inward if AW_HIDE is used or expand outward if the AW_HIDE is not used. The various direction flags have no effect.

AW_HOR_POSITIVE

Animates the window from left to right. This flag can be used with roll or slide animation. It is ignored when used with AW_CENTER or AW_BLEND.

AW_HOR_NEGATIVE

Animates the window from right to left. This flag can be used with roll or slide animation. It is ignored when used with AW_CENTER or AW_BLEND.

AW_VER_POSITIVE

Animates the window from top to bottom. This flag can be used with roll or slide animation. It is ignored when used with AW_CENTER or AW_BLEND.

AW_VER_NEGATIVE

Animates the window from bottom to top. This flag can be used with roll or slide animation. It is ignored when used with AW_CENTER or AW_BLEND.

参数有点多但归纳一下就知道分为水平方向，垂直方向，由里向外或由外向里这几种。

下面给出这个动画显示窗口类的使用范例。

代码中的CenterWindow是用来将窗口居中显示的，这个函数中的GetSystemMetrics(SM_CXSCREEN);和GetSystemMetrics(SM_CYSCREEN);可以参考《VC++获取屏幕大小第一篇像素大小GetSystemMetrics》。

}

运行效果如下所示，当然动画效果不好截图，大家可以从http://download.csdn.net/detail/morewindows/5128647下载（带源码且免积分），然后自己运行看下效果。

欢迎继续参考下面两篇《Windows界面编程第七篇文件拖拽(文件拖放)》和
