1、VC技巧四 - 工具條和狀態(tài)條增強(qiáng)型的狀態(tài)條 首先在你的應(yīng)用中添加一個(gè)新類，這個(gè)類的基類是CStatusBar類。本文中這個(gè)類叫做CEnhanceStatusBar。在頭文件中聲明以下的控件ID和標(biāo)志：#define IDC_PROGRESS 3001 /進(jìn)程條#define IDC_INFOBUTTON 3002 /Info按鈕#define IDC_LEFTBUTTON 3003 /左移按鈕#define IDC_RIGHTBUTTON 3004 /右移按鈕#define ENHANCEBAR_PROGRESS 1 /進(jìn)程條標(biāo)志#define ENHANCEBAR_INFO 2 /Info

2、按鈕標(biāo)志#define ENHANCEBAR_BUTTON 4 /左、右移按鈕標(biāo)志將下列成員函數(shù)和成員變量添加到CEnhanceStatusBar類中，并且根據(jù)你的需要設(shè)置其屬性為public/protected/private：CBitmapButton LeftButton; /左移按鈕CBitmapButton RightButton; /右移按鈕CBitmapButton InfoButton; /Info按鈕CProgressCtrl ProgressControl; /進(jìn)程條/下面的四個(gè)成員函數(shù)返回各個(gè)控件：CBitmapButton& GetLeftButton() re

3、turn LeftButton;CBitmapButton& GetRightButton() return RightButton;CBitmapButton& GetInfoButton() return InfoButton;CProgressCtrl& GetProgressControl() return ProgressControl;UINT ButtonWidth; /按鈕寬度UINT ButtonHeight; /按鈕高度UINT ButtonSpace; /按鈕間距int StatusFlags; /狀態(tài)條標(biāo)志int ProgressPane; /進(jìn)

4、程條所在的pane標(biāo)號(hào)int ButtonPane; /按鈕所在的pane標(biāo)號(hào)BOOL Create(CWnd* wnd, int flags, int progress, int button);/狀態(tài)條生成函數(shù)virtual BOOL AddButtonControl(); /添加按鈕控件virtual BOOL AddProgressControl(); /添加進(jìn)程條控件virtual void PositionControls(); /調(diào)整控件位置virtual void DestroyControls(); /刪除控件/下面是為了測(cè)試按鈕及進(jìn)程條控件而添加的一些函數(shù)及變量CStrin

5、gList Messages; /一組CString，用于存貯訊息POSITION CurrentMessagePosition; /當(dāng)前訊息在List中的位置virtual BOOL AddMessage(CString msg, int pos); /加入一條訊息virtual BOOL ClearMessages(); /刪除所有訊息virtual void SetProgress(BOOL show, int range); /設(shè)置進(jìn)程條編寫構(gòu)造函數(shù)和析構(gòu)函數(shù),并給Create()函數(shù)加入代碼：CEnhanceStatusBar:CEnhanceStatusBar() /初始化參數(shù) B

6、uttonWidth = 14; ButtonHeight = 13; ButtonSpace = 3; CurrentMessagePosition = 0; StatusFlags = 0; ProgressPane = 0; ButtonPane = 0;CEnhanceStatusBar:CEnhanceStatusBar() ClearMessages();/刪除所有訊息 DestroyControls();/刪除控件BOOL CEnhanceStatusBar:Create(CWnd* wnd, int flags, int progress, int button) if (m_

7、hWnd =0) if (!CStatusBar:Create(wnd) return FALSE; ClearMessages(); DestroyControls();/在通過菜單命令改變狀態(tài)條格式時(shí),這個(gè)調(diào)用很重要, /因?yàn)楦骺丶荒苌梢淮?所以必須先刪除 /得到標(biāo)志和pane號(hào) StatusFlags = flags;/flags標(biāo)志狀態(tài)條的格式，有無進(jìn)程條和某些按鈕等。 ProgressPane = progress;/progress表示狀態(tài)條所在的pane號(hào) ButtonPane = button;/button表示按鈕所在的pane號(hào) if (!AddProgressCont

8、rol()/加入進(jìn)程條 return FALSE; if (!AddButtonControl()/加入按鈕 return FALSE; /加入你自己的控件 /if (!AddCustomControl() / return FALSE; /加入你自己的控件 EnableToolTips(TRUE); PositionControls();/調(diào)整控件位置 /調(diào)整你自己的控件的位置 /PositionCustomControl(); /調(diào)整你自己的控件的位置 return TRUE;給AddButtonControl()、AddProgressControl()和DestroyControls(

9、)函數(shù)加入代碼：BOOL CEnhanceStatusBar:AddButtonControl() /設(shè)置ButtonRect CRect ButtonRect; ButtonRect.left = 100; ButtonRect.top = 2; ButtonRect.right = 114; ButtonRect.bottom = 15; /下面加入左移和右移按鈕 if (StatusFlags & ENHANCEBAR_BUTTON) if (!LeftButton.Create("",WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, But

10、tonRect,this, IDC_LEFTBUTTON) TRACE0("Failed to create LeftButton buttonn"); return FALSE; if (!LeftButton.LoadBitmaps(IDB_LEFTBUTTON,IDB_LEFTBUTTON_SEL,NULL, IDB_LEFTBUTTON_DIS) TRACE0("Failed to load LeftButton bitmapn"); return FALSE; LeftButton.EnableWindow(FALSE); if(!RightB

11、utton.Create("",WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, ButtonRect,this,IDC_RIGHTBUTTON) TRACE0("Failed to create RightButton buttonn"); return FALSE; if (!RightButton.LoadBitmaps(IDB_RIGHTBUTTON,IDB_RIGHTBUTTON_SEL, NULL,IDB_RIGHTBUTTON_DIS) TRACE0("Failed to load RightButton bit

12、mapn"); return FALSE; RightButton.EnableWindow(FALSE); /下面加入Info按鈕 if (StatusFlags & ENHANCEBAR_INFO) if (!InfoButton.Create("",WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, ButtonRect,this,IDC_INFOBUTTON) TRACE0("Failed to create InfoButtonn"); return FALSE; if (!InfoButton.LoadBitmaps(IDB_INFO,IDB_INFO_SEL,NULL,IDB_INFO_DIS) TRACE0("Failed to load InfoButton bitmapn"); return FALSE; InfoButt
