name="1">增强型的状态条</a></font></td></tr><tr><td><p>首先在你的应用中添加一个新类，这个类的基类是CStatusBar类。本文中这个类叫做CEnhanceStatusBar。<Br>在头文件中声明以下的控件ID和标志：<Br>#define IDC_PROGRESS 3001 //进程条<Br>#define IDC_INFOBUTTON 3002 //Info按钮<Br>#define IDC_LEFTBUTTON 3003 //左移按钮<Br>#define IDC_RIGHTBUTTON 3004 //右移按钮<Br></Br>#define ENHANCEBAR_PROGRESS 1 //进程条标志<Br>#define ENHANCEBAR_INFO 2 //Info按钮标志<Br>#define ENHANCEBAR_BUTTON 4 //左、右移按钮标志<Br></Br>将下列成员函数和成员变量添加到CEnhanceStatusBar类中，并且根据你的需要设置其属性为public/protected/private：<Br>CBitmapButton LeftButton; //左移按钮<Br>CBitmapButton RightButton; //右移按钮<Br>CBitmapButton InfoButton; //Info按钮<Br>CProgressCtrl ProgressControl; //进程条<Br></Br>//下面的四个成员函数返回各个控件：<Br>CBitmapButton& GetLeftButton() {return LeftButton;};<Br>CBitmapButton& GetRightButton() {return RightButton;};<Br>CBitmapButton& GetInfoButton() {return InfoButton;};<Br>CProgressCtrl& GetProgressControl() {return ProgressControl;};<Br></Br>UINT ButtonWidth; //按钮宽度<Br>UINT ButtonHeight; //按钮高度<Br>UINT ButtonSpace; //按钮间距<Br></Br>int StatusFlags; //状态条标志<Br>int ProgressPane; //进程条所在的pane标号<Br>int ButtonPane; //按钮所在的pane标号<Br></Br>BOOL Create(CWnd* wnd, int flags, int progress, int button);//状态条生成函数<Br>virtual BOOL AddButtonControl(); //添加按钮控件<Br>virtual BOOL AddProgressControl(); //添加进程条控件<Br>virtual void PositionControls(); //调整控件位置<Br>virtual void DestroyControls(); //删除控件<Br></Br>//下面是为了测试按钮及进程条控件而添加的一些函数及变量<Br>CStringList Messages; //一组CString，用于存贮讯息<Br>POSITION CurrentMessagePosition; //当前讯息在List中的位置<Br>virtual BOOL AddMessage(CString msg, int pos); //加入一条讯息<Br>virtual BOOL ClearMessages(); //删除所有讯息<Br>virtual void SetProgress(BOOL show, int range); //设置进程条<Br></Br>编写构造函数和析构函数,并给Create()函数加入代码：<Br>CEnhanceStatusBar::CEnhanceStatusBar()<Br>{<Br> //初始化参数<Br> ButtonWidth = 14;<Br> ButtonHeight = 13;<Br> ButtonSpace = 3;<Br> CurrentMessagePosition = 0;<Br> StatusFlags = 0;<Br> ProgressPane = 0;<Br> ButtonPane = 0;<Br>}<Br></Br>CEnhanceStatusBar::~CEnhanceStatusBar()<Br>{<Br> ClearMessages();//删除所有讯息<Br> DestroyControls();//删除控件<Br>}<Br></Br>BOOL CEnhanceStatusBar::Create(CWnd* wnd, int flags, int progress, int button)<Br>{<Br> if (m_hWnd ==0)<Br> {<Br> if (!CStatusBar::Create(wnd))<Br> return FALSE;<Br> }<Br> ClearMessages();<Br> DestroyControls();//在通过菜单命令改变状态条格式时,这个调用很重要,<Br> //因为各控件只能生成一次,所以必须先删除<Br></Br> //得到标志和pane号<Br> StatusFlags = flags;//flags标志状态条的格式，有无进程条和某些按钮等。<Br> ProgressPane = progress;//progress表示状态条所在的pane号<Br> ButtonPane = button;//button表示按钮所在的pane号<Br></Br> if (!AddProgressControl())//加入进程条<Br> return FALSE;<Br> if (!AddButtonControl())//加入按钮<Br> return FALSE;<Br> //加入你自己的控件<Br> //if (!AddCustomControl())<Br> // return FALSE;<Br> //加入你自己的控件<Br> EnableToolTips(TRUE);<Br> PositionControls();//调整控件位置<Br> //调整你自己的控件的位置<Br> //PositionCustomControl();<Br> //调整你自己的控件的位置<Br> return TRUE;<Br>}<Br></Br>给AddButtonControl()、AddProgressControl()和DestroyControls()函数加入代码：<Br>BOOL CEnhanceStatusBar::AddButtonControl()<Br>{<Br> //设置ButtonRect<Br> CRect ButtonRect;<Br> ButtonRect.left = 100;<Br> ButtonRect.top = 2;<Br> ButtonRect.right = 114;<Br> ButtonRect.bottom = 15;<Br></Br> //下面加入左移和右移按钮<Br> if (StatusFlags & ENHANCEBAR_BUTTON)<Br> {<Br> if (!LeftButton.Create("",WS_CHILD|WS_VISIBLE|BS_OWNERDRAW,<Br> ButtonRect,this, IDC_LEFTBUTTON))<Br> {<Br> TRACE0("Failed to create LeftButton button\n");<Br> return FALSE;<Br> }<Br> if (!LeftButton.LoadBitmaps(IDB_LEFTBUTTON,IDB_LEFTBUTTON_SEL,NULL,<Br> IDB_LEFTBUTTON_DIS))<Br> {<Br> TRACE0("Failed to load LeftButton bitmap\n");<Br> return FALSE;<Br> }<Br> LeftButton.EnableWindow(FALSE);<Br></Br> if(!RightButton.Create("",WS_CHILD|WS_VISIBLE|BS_OWNERDRAW,<Br> ButtonRect,this,IDC_RIGHTBUTTON))<Br> {<Br> TRACE0("Failed to create RightButton button\n");<Br> return FALSE;<Br> }<Br> if (!RightButton.LoadBitmaps(IDB_RIGHTBUTTON,IDB_RIGHTBUTTON_SEL,<Br> NULL,IDB_RIGHTBUTTON_DIS))<Br> {<Br> TRACE0("Failed to load RightButton bitmap\n");<Br> return FALSE;<Br> }<Br> RightButton.EnableWindow(FALSE);<Br> }<Br></Br> //下面加入Info按钮<Br> if (StatusFlags & ENHANCEBAR_INFO)<Br> {<Br> if (!InfoButton.Create("",WS_CHILD|WS_VISIBLE|BS_OWNERDRAW,<Br> ButtonRect,this,IDC_INFOBUTTON))<Br> {<Br> TRACE0("Failed to create InfoButton\n");<Br> return FALSE;<Br> }<Br> if (!InfoButton.LoadBitmaps(IDB_INFO,IDB_INFO_SEL,NULL,IDB_INFO_DIS))<Br> {<Br>

CEnhanceStatusBar::DestroyControls()<Br>{<Br> if (InfoButton.m_hWnd)<Br> InfoButton.DestroyWindow();//删除Info按钮<Br> if (LeftButton.m_hWnd)<Br> LeftButton.DestroyWindow();//删除左移按钮<Br> if (RightButton.m_hWnd)<Br> RightButton.DestroyWindow();//删除右移按钮<Br> if (ProgressControl.m_hWnd)<Br> ProgressControl.DestroyWindow();//删除进程条<Br> //删除你自己的控件<Br> //DestroyCustomControl();<Br> //删除你自己的控件<Br>}<Br></Br>给PositionControls()函数加入代码：<Br>void CEnhanceStatusBar::PositionControls()<Br>{<Br> if (StatusFlags & ENHANCEBAR_BUTTON)<Br> {<Br> if ((!LeftButton.m_hWnd || !RightButton.m_hWnd || ButtonPane == -1))<Br> return;<Br> CRect PaneRect, ButtonRect;<Br> //得到pane的大小，pane的宽度可以在CMainFrame的OnCreate()函数中设置<Br> GetItemRect(ButtonPane, &PaneRect);<Br> //计算ButtonRect<Br> ButtonRect.right = PaneRect.right - 1;<Br> ButtonRect.top = ((PaneRect.bottom - PaneRect.top) - ButtonHeight)/2<Br> + PaneRect.top;<Br> ButtonRect.bottom = ButtonRect.top + ButtonHeight;<Br> ButtonRect.left = ButtonRect.right - ButtonWidth;<Br> if (StatusFlags & ENHANCEBAR_INFO)<Br> {<Br> if ((!InfoButton.m_hWnd || ButtonPane == -1))<Br> return;<Br> InfoButton.MoveWindow(ButtonRect);//调整Info按钮的位置<Br> //计算ButtonRect<Br> ButtonRect.right = ButtonRect.left - ButtonSpace;<Br> ButtonRect.left = ButtonRect.right - ButtonWidth;<Br> }<Br> RightButton.MoveWindow(ButtonRect);//调整右移按钮的位置<Br> //计算ButtonRect<Br> ButtonRect.right = ButtonRect.left - ButtonSpace;<Br> ButtonRect.left = ButtonRect.right - ButtonWidth;<Br> LeftButton.MoveWindow(ButtonRect);//调整左移按钮的位置<Br> }<Br></Br> if (StatusFlags & ENHANCEBAR_PROGRESS)<Br> {<Br> if ((!ProgressControl.m_hWnd || ProgressPane == -1))<Br> return;<Br> CRect ProgressRect;<Br> GetItemRect(ProgressPane, &ProgressRect);//得到ProgressRect的大小<Br> if (ProgressControl.m_hWnd)<Br> ProgressControl.MoveWindow(ProgressRect);//调整进程条的位置<Br> }<Br>}<Br></Br>现在修改Mainfrm.cpp，修改其中indicators[]和OnCreate()函数：<Br>static UINT indicators[] =<Br>{<Br> ID_SEPARATOR, // status line indicator<Br> ID_INDICATOR_CONTROLS,//按钮<Br> ID_INDICATOR_MISC,//进程条<Br>};<Br></Br>int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)<Br>{......<Br> if (!m_wndStatusBar.Create(this, ENHANCEBAR_PROGRESS | ENHANCEBAR_INFO<Br> | ENHANCEBAR_BUTTON, 2, 1) || !m_wndStatusBar.SetIndicators<Br> (indicators, sizeof(indicators)/sizeof(UINT)))<Br>⌨️ 快捷键说明
