系统任务栏上下文菜单不会消失 [英] System tray context menu doesn't disappear

问题描述

我创建带有以下内容的通知图标:

I create a notification icon with:

notifyIcon.cbSize = sizeof(NOTIFYICONDATA);
notifyIcon.hWnd   = mainWnd;
notifyIcon.uID    = 100;
notifyIcon.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE;
notifyIcon.hIcon  = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_LOGO));
notifyIcon.dwState = NIS_SHAREDICON;
notifyIcon.uVersion = NOTIFYICON_VERSION;
notifyIcon.uTimeout = 15000;
notifyIcon.uCallbackMessage = APP_MSG_TRAY;
wcscpy_s(notifyIcon.szTip, 127, WTXT_APP_TRAY_TOOLTIP);

Shell_NotifyIcon(NIM_ADD, &notifyIcon);
Shell_NotifyIcon(NIM_SETVERSION, &notifyIcon);

在WM_RBUTTONDOWN和WM_CONTEXTMENU上弹出上下文菜单，如下所示:

And have a context menu popup on WM_RBUTTONDOWN and WM_CONTEXTMENU like this:

MENUITEMINFO separatorBtn = {0};
separatorBtn.cbSize = sizeof(MENUITEMINFO);
separatorBtn.fMask = MIIM_FTYPE;
separatorBtn.fType = MFT_SEPARATOR;

HMENU hMenu = CreatePopupMenu();

if(hMenu) {
 InsertMenu(hMenu, -1, MF_BYPOSITION, APP_OPEN_OPTIONS, WTXT_OPTIONS);
 InsertMenuItem(hMenu, -1, FALSE, &separatorBtn);
 InsertMenu(hMenu, -1, MF_BYPOSITION, APP_MSG_EXIT, WTXT_EXIT);

 POINT pt;
 GetCursorPos(&pt);
 SetForegroundWindow(mainWnd);
 TrackPopupMenu(hMenu, TPM_RIGHTBUTTON, pt.x, pt.y, 0, mainWnd, NULL);
 PostMessage(mainWnd, WM_NULL, 0, 0);
 DestroyMenu(hMenu);
}

它可以正常工作，但是上下文菜单不会总是消失.有时(经常)如果您有ie.winamp和系统托盘中的我的应用程序图标，如果右键单击我的应用程序，然后在winamp上显示，则将出现bot菜单，并且在单击某个项目之前，我的菜单不会自动消失.

It works fine, but the context menu doesn't disappear always. Sometimes (often) if you have ie. winamp and my app icons in system tray, if you right click my app and winamp afterwards, bot menus will appear, and my menu won't disappear automatically until you click an item.

有什么想法吗?

谢谢...

推荐答案

不捕获WM_RBUTTONDOWN，而是捕获WM_RBUTTONUP.当然，不要同时处理WM_RBUTTONUP和WM_CONTEXTMENU，因为它们将都得到处理，并且每次右键单击都会显示两次上下文菜单.两次显示菜单会产生您所描述的效果:菜单显示了，但似乎没有消失(因为它再次第二次显示了).

Do not catch WM_RBUTTONDOWN but WM_RBUTTONUP. And of course do not handle both WM_RBUTTONUP and WM_CONTEXTMENU, since they will both get handled and you'd show the context menu twice for every right-click. Showing the menu twice would have the effect you describe: the menu shows up, but doesn't seem to disappear (because it shows up again right away a second time).
