• 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。

    9.     void SetWindowHwnd(HWND hwnd); 
    10.     HWND GetWindowHwnd();

    9. CAnimateWindow::CAnimateWindow(HWND hwnd) 
    10. { 
    11.     m_hwndWindow = hwnd; 
    12.     m_nAnimateType = GetRandomNumber();

    25. BOOL CAnimateWindow::AnimateWindow(DWORD dwTime,BOOL bShow, BOOL bSlide) 
    26. { 
    27.     DWORD dwFlags; 
    28.     dwFlags = bShow ? AW_ACTIVATE : AW_HIDE; 
    29.     dwFlags |= bSlide ? AW_SLIDE : AW_BLEND; 
    30.     if (m_nAnimateType == 0) 
    31.         dwFlags |= AW_HOR_POSITIVE; 
    32.     elseif (m_nAnimateType == 1) 
    33.         dwFlags |= AW_VER_POSITIVE; 
    34.     else 
    35.         dwFlags |= AW_CENTER; 
    36.  
    37.     return ::AnimateWindow(m_hwndWindow, dwTime, dwFlags); 
    38. } 
    39.  
    40. int CAnimateWindow::GetRandomNumber() 
    41. { 
    42.     srand((UINT)time(NULL)); 
    43.     return rand() % 3; 
    44. } 

    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》。

    64. { 
    65.     RECT   rcDlg; 
    66.     int    nDlgWidth, nDlgHight; 
    67.     int    nScreenWidth, nScreenHight; 
    68.      
    69.     nScreenWidth = GetSystemMetrics(SM_CXSCREEN); 
    70.     nScreenHight = GetSystemMetrics(SM_CYSCREEN); 
    71.      
    72.     GetWindowRect(hwnd, &rcDlg); 
    73.     nDlgWidth = rcDlg.right - rcDlg.left; 
    74.     nDlgHight = rcDlg.bottom - rcDlg.top; 
    75.      
    76.     MoveWindow(hwnd, (nScreenWidth  - nDlgWidth) / 2, (nScreenHight - nDlgHight) / 2, nDlgWidth, nDlgHight, FALSE); 
    77. }  

    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。
