实验五 菜单、工具栏、状态栏程序设计

实验五菜单、工具栏、状态栏程序设计

【实验目的】

1、掌握主菜单程序设计方法

2、学会工具栏程序设计

3、掌握快捷菜单程序设计方法

4、学会增加状态栏窗格

【实验内容】

1、建立一个单文档应用程序，添加菜单显示，其中包含“文本”和“图形”2

个菜单项，分别输出文本和图形。

参考代码：

void CSDIDispView::OnText()

{

// TODO: Add your command handler code here

CClientDC dc(this);

dc.TextOut(20,20,"我已经学会了如何设计菜单程序!");

}

void CSDIDispView::OnPicture()

{

// TODO: Add your command handler code here

CClientDC dc(this);

CBrush *BrushOld,BrushNew;

BrushNew.CreateSolidBrush(RGB(255,0,0));

BrushOld=dc.SelectObject(&BrushNew); //选用画刷

dc.Rectangle(50,50,250,150);

dc.SelectObject(BrushOld); //还原画刷

BrushNew.DeleteObject(); //释放画刷

}

2、为上述应用程序添加菜单控制功能，选中“文本”时，“图形”菜单项无效；

当选中“图形”时，“文本”菜单项无效。

参考代码：

void CSDIDispView::OnText()

{

// TODO: Add your command handler code here

CClientDC dc(this);

dc.TextOut(20,20,"我已经学会了如何设计菜单程序!");

m_picture=false;

}

void CSDIDispView::OnPicture()

{

// TODO: Add your command handler code here

CClientDC dc(this);

CBrush *BrushOld,BrushNew;

BrushNew.CreateSolidBrush(RGB(255,0,0));

BrushOld=dc.SelectObject(&BrushNew); //选用画刷

dc.Rectangle(50,50,250,150);

dc.SelectObject(BrushOld); //还原画刷

BrushNew.DeleteObject(); //释放画刷

m_text=false;

}

void CSDIDispView::OnUpdateText(CCmdUI* pCmdUI)

{

// TODO: Add your command update UI handler code here

pCmdUI->Enable(m_text);

}

void CSDIDispView::OnUpdatePicture(CCmdUI* pCmdUI)

{

// TODO: Add your command update UI handler code here

pCmdUI->Enable(m_picture);

}

3、为上述应用程序工具栏添加两个工具按钮，单击第一个按钮，在视图窗口中弹出“打开文件”对话框，单击第二个按钮，在消息框中显示文本信息。

参考代码：

void CXiTi4_3View::OnText()

{

// TODO: Add your command handler code here

MessageBox("我已经学会了使用默认工具栏了！");

}

4、创建一个单文档应用程序，在状态栏中显示鼠标光标的坐标。

(1)在MainFrm.h中将状态栏对象修改为public

public:

CStatusBar m_wndStatusBar;

(2)在MainFrm.cpp中添加状态栏窗格ID_INDICATOR_COR

(3)在串表中设置添加窗格的字符串格式

(4)添加WM_MOUSEMOVE消息及其相应函数

void CXiTi4_4View::OnMouseMove(UINT nFlags, CPoint point)

{

// TODO: Add your message handler code here and/or call default

CString str;

CMainFrame *pFrame=(CMainFrame*)AfxGetApp()->m_pMainWnd;

CStatusBar *pStatus=&pFrame->m_wndStatusBar;

str.Format("%d,%d",point.x,point.y);

pStatus->SetPaneText(pStatus->CommandToIndex(ID_INDICATOR_COR),str);

CView::OnMouseMove(nFlags, point);

}

5、建立一个单文档应用程序，添加“时间”主菜单项，包含时、分、秒三

个菜单项，分别在视图窗口中显示当前系统时间的时、分和秒。添加相

应的工具栏和快捷菜单，并在状态栏中显示系统时间。

(1)添加菜单项、添加工具栏

插入工具栏并编辑，添加工具栏类

定义工具栏对象：

CToolBar m_wndToolBar, m_wndToolBar1;

加载工具栏：

OnCreate( ):

if (!m_wndToolBar1.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP

| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||

!m_wndToolBar1.LoadToolBar(IDR_TOOLBAR1))

{

TRACE0("Failed to create toolbar\n");

return -1; // fail to create

}

m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);

m_wndToolBar1.EnableDocking(CBRS_ALIGN_ANY);

EnableDocking(CBRS_ALIGN_ANY);

DockControlBar(&m_wndToolBar);

DockControlBar(&m_wndToolBar1);

设置时钟：

SetTimer(1,1000,NULL);

(2)添加状态栏

添加状态栏窗格：

ID_INDICATOR_TIME,

设置字符串格式

状态栏数据成员设置为公有成员

void CMainFrame::OnTimer(UINT nIDEvent)

{

// TODO: Add your message handler code here and/or call default

CTime time;

time=CTime::GetCurrentTime();//获得系统时间

CString str=time.Format("%H:%M:%S");//将系统时间转换成时:分:秒格式的字符串

m_wndStatusBar.SetPaneText(m_https://www.360docs.net/doc/fe15253200.html,mandToIndex(ID_INDICAT OR_TIME),str);//更新时间窗格显示的时间内容

CFrameWnd::OnTimer(nIDEvent);

}

void CMainFrame::OnClose()

{

// TODO: Add your message handler code here and/or call default

KillTimer(1);//关闭计时器

CFrameWnd::OnClose();

}

(3)添加菜单消息响应

定义CTime类的对象time

添加菜单消息响应函数：

void CSTimeView::OnSecond()

{

// TODO: Add your command handler code here

time=CTime::GetCurrentTime();//获得系统时间

CString str=time.Format("%S");//将系统时间转换成秒格式的字符串CClientDC dc(this);

dc.TextOut(100,100,"现在是"+str+"秒");

}

void CSTimeView::OnHour()

{

// TODO: Add your command handler code here

time=CTime::GetCurrentTime();//获得系统时间

CString str=time.Format("%H");//将系统时间转换成时格式的字符串CClientDC dc(this);

dc.TextOut(100,100,"现在是"+str+"时");

}

void CSTimeView::OnMinute()

{

// TODO: Add your command handler code here

time=CTime::GetCurrentTime();//获得系统时间

CString str=time.Format("%M");//将系统时间转换成分格式的字符串CClientDC dc(this);

dc.TextOut(100,100,"现在是"+str+"分");

}

(4)添加快捷菜单

设计快捷菜单

添加WM_ContextMenu消息响应函数：

void CSTimeView::OnContextMenu(CWnd*, CPoint point)

{

// CG: This block was added by the Pop-up Menu component

{

if (point.x == -1 && point.y == -1){

//keystroke invocation

CRect rect;

GetClientRect(rect);

ClientToScreen(rect);

point = rect.TopLeft();

point.Offset(5, 5);

}

CMenu menu;

VERIFY(menu.LoadMenu(CG_IDR_POPUP_STIME_VIEW));

CMenu* pPopup = menu.GetSubMenu(0);

ASSERT(pPopup != NULL);

CWnd* pWndPopupOwner = this;

while (pWndPopupOwner->GetStyle() & WS_CHILD)

pWndPopupOwner = pWndPopupOwner->GetParent();

pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,

pWndPopupOwner);

}

}

6、绘制正弦和余弦曲线，设置线型和颜色的变换。

1）

添加菜单

添加工具栏资源

添加快捷菜单资源

2）加载工具栏：

Mainfrm.h:

CToolBar m_wndToolBar1;

Mainfrm.cpp:

Oncreate:

if (!m_wndToolBar1.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP

| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||

!m_wndToolBar1.LoadToolBar(IDR_TOOLBAR1))

{

TRACE0("Failed to create toolbar\n");

return -1; // fail to create

}

// TODO: Delete these three lines if you don't want the toolbar to

// be dockable

m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);

m_wndToolBar1.EnableDocking(CBRS_ALIGN_ANY);

EnableDocking(CBRS_ALIGN_ANY);

DockControlBar(&m_wndToolBar);

DockControlBar(&m_wndToolBar1);

3）加载快捷菜单：

添加视图类得wm_context消息

void CP1View::OnContextMenu(CWnd* pWnd, CPoint point)

{

// TODO: Add your message handler code here

CMenu menu,*pPopup;

menu.LoadMenu(IDR_MENU1); //加载快捷菜单

pPopup = menu.GetSubMenu(0);

CWnd* pWndPopupOwner = this;

pWndPopupOwner = pWndPopupOwner->GetParent();

//显示快捷菜单

pPopup->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,point.x, point.y,pWndPopupOwner);

4）添加视图类的成员变量及成员函数

Cview.h

const double PI=3.1416;

double y;

y=cos(x*PI/180);

return y;

}

void CCurveView::drawaxis(CDC *pDC)

{

CString str;

CFont myfont,*oldfont;

myfont.CreatePointFont(80,"Arial",pDC);

oldfont=pDC->SelectObject(&myfont);

drawline(pDC,50,10,50,290);

drawline(pDC,45,150,780,150);

for(int i=50;i<780;i=i+90)

{

drawline(pDC,i,145,i,150);

str.Format("%d",i-50);

if((i-50)!=0) pDC->TextOut(i,155,str);

}

for(i=0;i<11;i++)

{

drawline(pDC,50,50+20*i,55,50+20*i);

str.Format("%.2f",1-0.2*i);

if(i!=5) pDC->TextOut(15,45+20*i,str);

else pDC->TextOut(15,45+20*i,"0");

}

pDC->SelectObject(oldfont);

myfont.DeleteObject();

}

pDC->MoveTo(x1,y1);

pDC->LineTo(x2,y2);

}

void CCurveView::drawcurve(CDC* pDC)

{

drawaxis(pDC);

CPoint point[750];

CPen mypen,*oldpen;

mypen.CreatePen(PS_SOLID,m_wid,m_col);

oldpen=pDC->SelectObject(&mypen);

for(int i=0;i<722;i++)

{

point[i].x=i+50;

if(m_typ==1)

point[i].y=(int)(150-calsin(i)*100);

else if(m_typ==2)

point[i].y=(int)(150-calcos(i)*100);

}

for(i=0;i<721;i++)

drawline(pDC,point[i].x,point[i].y,point[i+1].x,point[i+1].y);

pDC->SelectObject(oldpen);

mypen.DeleteObject();

}

5）添加菜单消息响应函数

{

// TODO: Add your command handler code here

m_col=RGB(0,0,255);

Invalidate();

void CCurveView::OnUpdateColb(CCmdUI* pCmdUI)

{

// TODO: Add your command update UI handler code here pCmdUI->Enable(m_able);

if(m_col==RGB(0,0,255))

pCmdUI->SetCheck(true);

else

pCmdUI->SetCheck(false);
