托盘程序
制作系统托盘程序 VC 点击数：695 发布日期：2006-9-24 12:32:00 【收藏】 【评论】 【打印】 【编程爱好者论坛】 【关闭】 其实，在任务条上添加托盘比较容易实现，调用VC中的函数就可以解决，只是注意协调。接下来，我将给大家提供一个类，可以很容易的达到我们的目的，希望它能给大家一点帮助，如果你发现BUG也欢迎你和我联系。运行程序，左键双击或者右键单击任务条上的托盘，我们可以看到效果。 1. 有关类CsystemTray的说明：（文章的最后有本类的具体实现代码） CSystemTray是CObject的扩展类，实现以下功能： 1、在任务条显示托盘图标。 2、设置提示Tip 3、设置图标的形状 主要函数说明： Create(CWnd* pWnd, UINT uCallbackMessage, LPCTSTR szTip, HICON icon, UINT uID); 功能： 生成一个图标。 参数说明： pWnd：程序的主窗口， uCallbackMessage：对应的消息映射， szTip：鼠标停留时的提示文字， icon：显示的图标， uID：与之对应的菜单ID · BOOL CSystemTray::SetIcon(HICON hIcon) BOOL CSystemTray::SetIcon(LPCTSTR lpszIconName) BOOL CSystemTray::SetIcon(UINT nIDResource) BOOL CSystemTray::SetStandardIcon(LPCTSTR lpIconName) BOOL CSystemTray::SetStandardIcon(UINT nIDResource) 功能：更改托盘上的图标。 void CSystemTray::ShowIcon() 功能：显示图标。 · BOOL CSystemTray::SetTooltipText(LPCTSTR pszTip) BOOL CSystemTray::SetTooltipText(UINT nID) 功能：提示显示文字。 2. 使用本类的步骤如下： 第一步：在VC编程环境下，建立一个工程，基于对话框或者是单文档（或者是多文档）你随便，所有的选项都取默认值即可。 第二步：在mainfrm.h中定义变量CSystemTray m_TrayIcon;并添加函数声明： afx_msg LRESULT OnTrayNotification(WPARAM wParam, LPARAM lParam); afx_msg void OnSysCommand(UINT nID, LPARAM lParam); 第三步：在StaAFX.h中定义消息： #define WM_ICON_NOTIFY WM_USER + 1 第四步：自定义菜单IDR_POPUPMENU，其中最少包括一项：ID：ID_VIEW_MAIN_WINDOW，Caption为"显示主窗口"，并为该项在类CmainFrame中添加消息映射函数，COMMAND和UPDATE_COMMAND_UI。 第五步：在Mainframe.cpp中添加以下内容： 1. BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd) ON_COMMAND(ID_VIEW_MAIN_WINDOW, OnViewMainWindow) ON_UPDATE_COMMAND_UI(ID_VIEW_MAIN_WINDOW, OnUpdateViewMainWindow) ON_MESSAGE(WM_ICON_NOTIFY, OnTrayNotification) ON_WM_SYSCOMMAND() //}}AFX_MSG_MAP END_MESSAGE_MAP() 2. void CMainFrame::OnViewMainWindow() { if(IsWindowVisible()) { ShowWindow(SW_SHOWMINIMIZED); ShowWindow(SW_HIDE); m_TrayIcon.SetIcon(IDI_ICON1); } else { ShowWindow(SW_SHOW); ShowWindow(SW_RESTORE); m_TrayIcon.SetIcon(IDI_ICON2); } } void CMainFrame::OnUpdateViewMainWindow(CCmdUI* pCmdUI) { pCmdUI->SetCheck(IsWindowVisible()); } 3. int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; //创建托盘图标 if (!m_TrayIcon.Create(this, WM_ICON_NOTIFY,"大屏实时显示程序", NULL, IDR_POPUPMENU)) return -1; m_TrayIcon.SetIcon(IDI_ICON1); SetMenu(NULL); return 0; } 4. LRESULT CMainFrame::OnTrayNotification(WPARAM wParam, LPARAM lParam) { if (wParam != IDR_POPUPMENU) return 0L; CMenu menu, *pSubMenu; if (LOWORD(lParam) == WM_RBUTTONUP) { CPoint pos; GetCursorPos(&pos;); if (!menu.LoadMenu(IDR_POPUPMENU)) return 0; if (!(pSubMenu=menu.GetSubMenu(0))) return 0; ::SetMenuDefaultItem(pSubMenu->m_hMenu, 3, TRUE); SetForegroundWindow(); pSubMenu->TrackPopupMenu(TPM_RIGHTALIGN | TPM_BOTTOMALIGN | TPM_RIGHTBUTTON, pos.x, pos.y, this); menu.DestroyMenu(); } else if (LOWORD(lParam) == WM_LBUTTONDBLCLK) { if (!menu.LoadMenu(IDR_POPUPMENU)) return 0; if (!(pSubMenu = menu.GetSubMenu(0))) return 0; SetForegroundWindow(); //激活第2个菜单项 SendMessage(WM_COMMAND, pSubMenu->GetMenuItemID(1), 0); menu.DestroyMenu(); } return 0; } void CMainFrame::OnSysCommand(UINT nID, LPARAM lParam) { if(nID==SC_MINIMIZE) { ShowWindow(SW_SHOWMINIMIZED); ShowWindow(SW_HIDE); } else CFrameWnd::OnSysCommand(nID, lParam); } 3. 附录：类的实现代码 CsystemTray的头文件 #ifndef _INCLUDED_SYSTEMTRAY_H_ #define _INCLUDED_SYSTEMTRAY_H_ ///////////////////////////////////////////////////////////////////////////// // CSystemTray window class CSystemTray : public CObject { // Construction/destruction public: CSystemTray(); CSystemTray(CWnd* pWnd, UINT uCallbackMessage, LPCTSTR szTip, HICON icon, UINT uID); virtual ~CSystemTray(); // Operations public: CFrameWnd * m_pFrame; BOOL Enabled() { return m_bEnabled; } BOOL Visible() { return !m_bHidden; } //Create the tray icon Create(CWnd* pWnd, UINT uCallbackMessage, LPCTSTR szTip, HICON icon, UINT uID); //Change or retrieve the Tooltip text BOOL SetTooltipText(LPCTSTR pszTooltipText); BOOL SetTooltipText(UINT nID); CString GetTooltipText() const; //Change or retrieve the icon displayed BOOL SetIcon(HICON hIcon); BOOL SetIcon(LPCTSTR lpIconName); BOOL SetIcon(UINT nIDResource); BOOL SetStandardIcon(LPCTSTR lpIconName); BOOL SetStandardIcon(UINT nIDResource); HICON GetIcon() const; void HideIcon(); void ShowIcon(); void RemoveIcon(); void MoveToRight(); //Change or retrieve the window to send notification messages to BOOL SetNotificationWnd(CWnd* pNotifyWnd); CWnd* GetNotificationWnd() const; //Default handler for tray notification message // Overrides // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CSystemTray) //}}AFX_VIRTUAL // Implementation protected: BOOL m_bEnabled; // does O/S support tray icon?
