二、QQ淡出淡出显示实现

其实用到一个API函数:AnimateWindow,下面是这个函数的一些说明:

The AnimateWindow function enables you to produce special effects when showing or hiding windows.
There are two types of animation: roll animation and slide animation.
BOOL AnimateWindow(
     HWND hwnd, // handle to the window to animate
     DWORD dwTime, // duration of animation
     DWORD dwFlags // animation type
     );

上面的函数前两个参数一看就明白,不用说了,最后一个参数dwFlags设置动画窗口的样式:

Specifies the type of animation. This parameter can be one or more of the following flags.

各种标志说明:

标志 说明
AW_SLIDE Uses slide animation. By default, roll animation is used.
This flag is ignored when used with the AW_CENTER flag.
AW_ACTIVATE Activates the window. Do not use this flag 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 the AW_HIDE flag is used or expand outward
if the AW_HIDE flag is not used.
AW_HOR_POSITIVE Animate the window from left to right. This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
AW_HOR_NEGATIVE Animate the window from right to left. This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
AW_VER_POSITIVE Animate the window from top to bottom. This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
AW_VER_NEGATIVE Animate the window from bottom to top. This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.

以上内容是从MSDN中摘录的,要淡入淡出的效果的话,用到AW_BELND。

三、控制窗口显示的代码

CMainFrame::OnCreate(…)
{
  //...
  AnimateWindow(GetSafeHwnd(),1000,AW_CENTER|AW_BLEND);
  //…
}

四、关闭的代码

CMainFrame::OnClose(..)
{
  AnimateWindow(GetSafeHwnd(),1000,AW_HIDE|AW_CENTER|AW_BLEND);
}

其实AnimateWindow只是利用了windows本身的方法,如果您要更加有个性的窗口效果,那就得多做写些代码了,一分辛苦,一分收获吧

就这写这么多吧,不明白的,一看源码,二查MSDN,三请教高手。

五、结束语

其实就MSN的提示窗口来说,如果要从使用复杂一点的背景和效果,那么还有刷新屏幕的问题,应做到无闪刷新.由于时间苍促,不足之处必然有之,同时以上代码也参考了一部分以前 VCKBASE 技术文档,在此表示感谢!

如果有问题,欢迎交流!共同进步!
