C++编写的托盘图标

C++编写的托盘图标,如果响应此图标的消息(Win32下,非MFC中)

Answer 1

声明一个自定义消息用于响应托盘消息：#define WM_NOTIFYICON WM_USER + 0x01 在CreateWindow后添加如下代码创建托盘图标： // 需添加头文件Shellapi.h
NOTIFYICONDATA nid = {0};
nid.cbSize = sizeof(NOTIFYICONDATA);
nid.hWnd = hWnd;
nid.uID = IDI_SMALL;
nid.hIcon = ::LoadIcon(hInst, MAKEINTRESOURCE(IDI_SMALL));
nid.uCallbackMessage = WM_NOTIFYICON;
nid.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP;
_tcscpy(nid.szTip, _T("托盘响应"));
::Shell_NotifyIcon(NIM_ADD, &nid); 在窗体过程函数中添加如下代码：case WM_NOTIFYICON:
if ((wParam == IDI_SMALL) && (lParam == WM_LBUTTONDOWN)) // 鼠标左键按下时响应
{
MessageBox(hWnd, _T("df"), NULL, MB_OK);
}
break; 在WM_DESTORY消息中销毁托盘图标
case WM_DESTROY:
// NOTIFYICONDATA nid = {0}; 语句放在switch前面
nid.hWnd = hWnd;
nid.uID = IDI_SMALL; // 托盘图标ID
::Shell_NotifyIcon(NIM_DELETE, &nid); PostQuitMessage(0);
break;
