MFC工具栏

相关类:

CToolBarCtrl - 父类是 CWnd  封装了工具栏控件相关操作
CToolBar - 父类是CControlBar  封装了工具栏和框架窗口之间的关系
工具栏使用:
//把工具栏对象定义为 CMyFrameWnd成员:
CToolBar toolbar;
//在窗口创建时,加载工具栏资源
int CMyFrameWnd::OnCreate(LPCREATESTRUCT lpc)
{
toolbar.CreateEx(this,TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_ALIGN_TOP|CBRS_GRIPPER|CBRS_SIZE_DYNAMIC|CBRS_TOOLTIPS|CBRS_FLYBY);
toolbar.LoadToolBar(IDR_TOOLBAR1);
toolbar.EnableDocking(CBRS_ALIGN_ANY);//设置工具栏准备停靠的位置:
this->EnableDocking(CBRS_ALIGN_ANY);//框架窗口允许停靠的位置
this->DockControlBar(&toolbar,AFX_IDW_DOCKBAR_BOTTOM);//框架窗口设置初始停靠的位置
return CFrameWnd::OnCreate(lpc);
}
//工具栏风格:
TBSTYLE_FLAT:平滑风格
CBRS_GRIPPER:有推动把手
CBRS_SIZE_DYNAMIC:动态改变形状
CBRS_TOOLTIPS:能提示文字
CBRS_FLYBY:在状态栏显示提示




//映射消息,使用ID绑定COMMAND事件
ON_COMMAND(IDM_new,OnNew)
TOOLBAR的提示格式示例:新建\n新建,
\n前面的文字用于状态栏显示,后面的用于tooltip提示
//控制工具栏显示与隐藏:ShowControlBar(),
是否为显示状态:IsWindowVisible()
void CMyFrameWnd::ShowToolBar()
{
this->ShowControlBar(&toolbar,!toolbar.IsWindowVisible(),FALSE);
menu.CheckMenuItem(IDM_toolbar,MF_BYCOMMAND|toolbar.IsWindowVisible()?MF_CHECKED:MF_UNCHECKED);
}


MFC状态栏

相关类:

CStatusBar - 父类是 CControlBar,封装了状态栏的创建和各种操作
状态栏的使用:
创建状态栏:
CStatusBar statusbar;
statusbar.CreateEx(this,TBSTYLE_FLAT);


设置指示器:
在字符串表中加字符串:IDS_TIME,IDS_POS
全局数组:
UINT g_hIndicator[]={
0,IDS_TIME,IDS_POS
};//ID为0的为默认指示器
statusbar.SetIndicators(g_hIndicator,sizeof(g_hIndicator)/sizeof(UINT));
//修改每个指示器的风格(包括宽度)
statusbar.SetPaneInfo(1,IDS_TIME,SBPS_NORMAL,200);
statusbar.SetPaneInfo(2,IDS_POS,SBPS_NORMAL,100);
::SetTimer(this->m_hWnd,1,1000,NULL);//定时器
ON_WM_TIMER()
 void CMyFrameWnd::OnTimer(UINT uid)
 {
SYSTEMTIME st={0};
::GetLocalTime(&st);
CString str;
str.Format("%d-%d-%d %d:%d:%d",st.wYear,st.wMonth,st.wDay,
st.wHour,st.wMinute,st.wSecond);
statusbar.SetPaneText(1,str,TRUE);//设置文字到指示器
 }
//鼠标移动实时显示鼠标位置
ON_WM_MOUSEMOVE()
void CMyFrameWnd::OnMouseMove(UINT id, CPoint pt)
{
CString str;
str.Format("x=%d,y=%d",pt.x,pt.y);
statusbar.SetPaneText(2,str);
}

MFC 视图窗口

提供一个显示数据的窗口,与用户进行交互

  相关类:CView  父类为 CWnd
写CMyView类派生自CView
在框架的WM_CREATE处理函数中创建CMyView对象
CMyView * pView=new CMyView;
pView->Create(NULL,"myview",WS_CHILD|WS_VISIBLE,CRect(0,0,200,200),this,AFX_IDW_PANE_FIRST);
m_pViewActive=pView;//设置为活跃视图
//重写纯虚函数
void CMyView::OnDraw(CDC* pDC)
{
pDC->TextOut(100,100,"CMyView::OnDraw");
}

在CView中,如果有消息调用OnPaint(),则不调用 OnDraw(),建议只写OnDraw。


工具栏,状态栏使用:

#include <afxwin.h>
#include <AFXEXT.H>


cpp文件代码:

// MFCtoolbar.cpp : Defines the entry point for the application.//#include "stdafx.h"#include "resource.h"UINT g_hIndicator[]={0,IDS_TIME,IDS_POS};class CMyFrameWnd:public CFrameWnd{DECLARE_MESSAGE_MAP()public:CToolBar toolbar;CMenu menu;CStatusBar statusbar;afx_msg int OnCreate(LPCREATESTRUCT lpc);afx_msg void OnNew();afx_msg void ShowToolBar();afx_msg void OnTimer(UINT uid);afx_msg void OnMouseMove(UINT id, CPoint pt);};void CMyFrameWnd::OnMouseMove(UINT id, CPoint pt){CString str;str.Format("x=%d,y=%d",pt.x,pt.y);statusbar.SetPaneText(2,str);} void CMyFrameWnd::OnTimer(UINT uid) { SYSTEMTIME st={0}; ::GetLocalTime(&st); CString str; str.Format("%d-%d-%d %d:%d:%d",st.wYear,st.wMonth,st.wDay, st.wHour,st.wMinute,st.wSecond); statusbar.SetPaneText(1,str,TRUE); }BEGIN_MESSAGE_MAP(CMyFrameWnd,CFrameWnd)ON_WM_CREATE()ON_COMMAND(IDM_new,OnNew)ON_COMMAND(IDM_toolbar,ShowToolBar)ON_WM_TIMER()ON_WM_MOUSEMOVE()//ON_COMMAND_RANGE(IDM_new,ID_blue,OnNew)END_MESSAGE_MAP()void CMyFrameWnd::OnNew(){AfxMessageBox("CMyFrameWnd::OnNew");}void CMyFrameWnd::ShowToolBar(){this->ShowControlBar(&toolbar,!toolbar.IsWindowVisible(),FALSE);menu.CheckMenuItem(IDM_toolbar,MF_BYCOMMAND|toolbar.IsWindowVisible()?MF_CHECKED:MF_UNCHECKED);}int CMyFrameWnd::OnCreate(LPCREATESTRUCT lpc){toolbar.CreateEx(this,TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_ALIGN_TOP|CBRS_GRIPPER|CBRS_SIZE_DYNAMIC|CBRS_TOOLTIPS|CBRS_FLYBY);toolbar.LoadToolBar(IDR_TOOLBAR1);toolbar.SetWindowText("工具栏");toolbar.EnableDocking(CBRS_ALIGN_ANY);this->EnableDocking(CBRS_ALIGN_ANY);this->DockControlBar(&toolbar,AFX_IDW_DOCKBAR_TOP);menu.LoadMenu(IDR_MENU1);SetMenu(&menu);statusbar.CreateEx(this,TBSTYLE_FLAT);statusbar.SetIndicators(g_hIndicator,sizeof(g_hIndicator)/sizeof(UINT));statusbar.SetPaneInfo(1,IDS_TIME,SBPS_NORMAL,200);statusbar.SetPaneInfo(2,IDS_POS,SBPS_NORMAL,100);::SetTimer(this->m_hWnd,1,1000,NULL);return CFrameWnd::OnCreate(lpc);}class CMyWinApp:public CWinApp{public:     virtual BOOL InitInstance();};CMyWinApp theApp;BOOL CMyWinApp::InitInstance(){    CMyFrameWnd *pFrame=new CMyFrameWnd;pFrame->Create(NULL,"TOOLBAR"/*,WS_OVERLAPPEDWINDOW,CFrameWnd::rectDefault,NULL,MAKEINTRESOURCE(IDR_MENU1)*/);m_pMainWnd=pFrame;   pFrame->ShowWindow(SW_SHOW);pFrame->UpdateWindow();return TRUE;}


视图窗口使用代码:

// MFCview.cpp : Defines the entry point for the application.//#include "stdafx.h"class CMyView:public CView{public:virtual void OnDraw(CDC* pDC);};void CMyView::OnDraw(CDC* pDC){pDC->TextOut(100,100,"CMyView::OnDraw");}class CMyFrameWnd:public CFrameWnd{DECLARE_MESSAGE_MAP()public:afx_msg void OnPaint();afx_msg int OnCreate(LPCREATESTRUCT lpc);};BEGIN_MESSAGE_MAP(CMyFrameWnd,CFrameWnd)ON_WM_PAINT()ON_WM_CREATE()END_MESSAGE_MAP()int CMyFrameWnd::OnCreate(LPCREATESTRUCT lpc){CMyView * pView=new CMyView;pView->Create(NULL,"myview",WS_CHILD|WS_VISIBLE,CRect(0,0,200,200),this,AFX_IDW_PANE_FIRST);m_pViewActive=pView;//设置为活跃视图//AFX_IDW_PANE_FIRST  为第一个视图窗口IDreturn CFrameWnd::OnCreate(lpc);}void CMyFrameWnd::OnPaint(){PAINTSTRUCT ps={0};HDC hdc=::BeginPaint(m_hWnd,&ps);::TextOut(hdc,100,100,"hello",5);::EndPaint(m_hWnd,&ps);}class CMyWinApp:public CWinApp{public:virtual BOOL InitInstance();};CMyWinApp theApp;BOOL CMyWinApp::InitInstance(){CMyFrameWnd *pFrame=new CMyFrameWnd;pFrame->Create(NULL,"MFCview");m_pMainWnd=pFrame;pFrame->ShowWindow(SW_SHOW);pFrame->UpdateWindow();return TRUE;}
