制作 MSN、QQ 的消息提示窗口
作者:
用过QQ和MSN聊天工具的人都知道,只要好友上线,就会在托盘的位置处显示一个提示窗口,
可以是拉帘式的,或者是淡入淡出的形式出现;想想何不为自己的程式也加一个漂亮的提示窗口呢:)
说做就做。
一、MSN拉帘式窗口制作
分三部分:1、窗口的显示;2、窗口的停留;3、窗口的消失;
如果达到这样郊果,系统中要有三个定时器,进行分别控制。定义的定时器如下:
#define ID_TIMER_POP_WINDOW 1 #define ID_TIMER_DISPALY_DELAY 2 #define ID_TIMER_CLOSE_WINDOW 3
从CWnd 继承一个窗口,当然也可以从CFrameWnd进行派生,这不是主要问题,关键是看你是怎么处理WM_PAINT,WM_MOUSEMOVE,WM_TIMER的消息。一般情况,我从OnPaint()中进行显示图片,在WM_TIMER中处理定时器消息,下面是处里定时器时用到的代码:
CMsgWnd::CMsgWnd() { ... SetTimer(ID_TIEMR_POP_WINDOW,20,NULL); ... } void CMsgWnd::OnTimer(UINT nIDEvent) { static int nHeight=0; int cy=GetSystemMetrics(SM_CYSCREEN); int cx=GetSystemMetrics(SM_CXSCREEN); RECT rect; SystemParametersInfo(SPI_GETWORKAREA,0,&rect,0); int y=rect.bottom-rect.top; int x=rect.right-rect.left; x=x-WIN_WIDTH; switch(nIDEvent) { case ID_TIMER_POP_WINDOW: if(nHeight<=WIN_HEIGHT) { nHeight; MoveWindow(x, y-nHeight, WIN_WIDTH, WIN_HEIGHT); Invalidate(FALSE); } else { KillTimer(ID_TIMER_POP_WINDOW); SetTimer(ID_TIMER_DISPLAY_DELAY,5000,NULL); } break; case ID_TIMER_CLOSE_WINDOW: if(nHeight>=0) { nHeight--; MoveWindow(x, y-nHeight, WIN_WIDTH, nHeight); } else { KillTimer(ID_TIMER_CLOSE_WINDOW); SendMessage(WM_CLOSE); } break; case ID_TIMER_DISPLAY_DELAY: KillTimer(ID_TIMER_DISPLAY_DELAY); SetTimer(ID_TIMER_CLOSE_WINDOW,20,NULL); break; } CWnd::OnTimer(nIDEvent); }根据你设的定时器的长短来控制窗口的显示过程;
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.
