VS2013 MFC Windows 程序设计之Accel

1.新建一个项目Accel，修改属性。创建头文件Accel.h和源文件Accel.cpp。

2.

#include <afxwin.h>#include "Accel.h"

class CMyWinApp : public CWinApp{};class CMyFrameWnd : public CFrameWnd{};

添加InitInstance函数:

3.

this->m_pMainWnd = new CMyFrameWnd;this->m_pMainWnd->ShowWindow(this->m_nCmdShow);this->m_pMainWnd->UpdateWindow();return TRUE;

构造函数的声明:

class CMyFrameWnd : public CFrameWnd{public:CMyFrameWnd();};

构造函数的定义，写都源文件里

CMyWinApp app;

CMyFrameWnd::CMyFrameWnd(){this->Create(NULL, TEXT("Accel"), WS_OVERLAPPEDWINDOW);}

4.单元格的高度、宽度和视图:

在类视图中，双击CMyFrameWnd，右击--添加--添加变量。

protected:int m_nCellWidth;int m_nCellHeight;int m_nRibbonWidth;int m_nViewWidth;//最大的显示。int m_nViewHeight;

6.我们要初始化上面的数据，初始化数据在创建窗口的时候。

CClientDC dc(this);m_nCellWidth = dc.GetDeviceCaps(LOGPIXELSX);//运用dc的方法。m_nCellHeight = dc.GetDeviceCaps(LOGPIXELSX) / 4;m_nRibbonWidth = m_nCellWidth / 2;m_nViewWidth = (26 * m_nCellWidth) + m_nRibbonWidth;m_nViewHeight = m_nCellHeight * 100;

7.添加OnPaint:

‘

CPen pen(PS_SOLID, 0, RGB(192, 192, 192));//宽度是0。CPen *pOldPen = dc.SelectObject(&pen);for (int i = 0; i < 99; i++){int y = (i * m_nCellHeight) + m_nCellHeight;dc.MoveTo(0, y);dc.LineTo(m_nViewWidth, y);}//上面是横线，我们在画上竖线。for (int j = 0; j < 26; j++){int x = (j*m_nCellWidth) + m_nRibbonWidth;dc.MoveTo(x, 0);dc.LineTo(x, m_nViewHeight);}dc.SelectObject(&pOldPen);//接下来，画行头。CBrush brush;brush.CreateStockObject(LTGRAY_BRUSH);CRect rcTop(0, 0, m_nViewWidth, m_nCellHeight);dc.FillRect(rcTop, &brush);CRect rcLeft(0, 0, m_nRibbonWidth, m_nViewHeight);dc.FillRect(rcLeft, &brush);dc.MoveTo(0, m_nCellHeight);dc.LineTo(m_nViewWidth, m_nCellHeight);dc.MoveTo(m_nRibbonWidth, 0);dc.LineTo(m_nRibbonWidth, m_nViewHeight);dc.SetBkMode(TRANSPARENT);for (int i = 0; i < 99; i++){int y = (i * m_nCellHeight) + m_nCellHeight;dc.MoveTo(0, y);dc.LineTo(m_nRibbonWidth, y);CString string;string.Format(TEXT("%d"), i + 1);CRect rect(0, y, m_nRibbonWidth, y + m_nCellHeight);dc.DrawText(string, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);rect.top++;dc.Draw3dRect(rect, RGB(255, 255, 255), RGB(128, 128, 128));}for (int j = 0; j < 26; j++){int x = (j* m_nCellWidth) + m_nRibbonWidth;dc.MoveTo(x, 0);dc.LineTo(x, m_nCellHeight);CString string;string.Format(TEXT("%c"), j + 'A');CRect rect(x, 0, x + m_nCellWidth, m_nCellHeight);dc.DrawText(string, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);rect.left++;dc.Draw3dRect(rect, RGB(255, 255, 255), RGB(128, 128, 128));}CPen pen(PS_SOLID, 0, RGB(192, 192, 192));//宽度是0。CPen *pOldPen = dc.SelectObject(&pen);for (int i = 0; i < 99; i++){int y = (i * m_nCellHeight) + m_nCellHeight;dc.MoveTo(0, y);dc.LineTo(m_nViewWidth, y);}//上面是横线，我们在画上竖线。for (int j = 0; j < 26; j++){int x = (j*m_nCellWidth) + m_nRibbonWidth;dc.MoveTo(x, 0);dc.LineTo(x, m_nViewHeight);}dc.SelectObject(&pOldPen);//接下来，画行头。CBrush brush;brush.CreateStockObject(LTGRAY_BRUSH);CRect rcTop(0, 0, m_nViewWidth, m_nCellHeight);dc.FillRect(rcTop, &brush);CRect rcLeft(0, 0, m_nRibbonWidth, m_nViewHeight);dc.FillRect(rcLeft, &brush);dc.MoveTo(0, m_nCellHeight);dc.LineTo(m_nViewWidth, m_nCellHeight);dc.MoveTo(m_nRibbonWidth, 0);dc.LineTo(m_nRibbonWidth, m_nViewHeight);dc.SetBkMode(TRANSPARENT);for (int i = 0; i < 99; i++){int y = (i * m_nCellHeight) + m_nCellHeight;dc.MoveTo(0, y);dc.LineTo(m_nRibbonWidth, y);CString string;string.Format(TEXT("%d"), i + 1);CRect rect(0, y, m_nRibbonWidth, y + m_nCellHeight);dc.DrawText(string, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);rect.top++;dc.Draw3dRect(rect, RGB(255, 255, 255), RGB(128, 128, 128));}for (int j = 0; j < 26; j++){int x = (j* m_nCellWidth) + m_nRibbonWidth;dc.MoveTo(x, 0);dc.LineTo(x, m_nCellHeight);CString string;string.Format(TEXT("%c"), j + 'A');CRect rect(x, 0, x + m_nCellWidth, m_nCellHeight);dc.DrawText(string, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);rect.left++;dc.Draw3dRect(rect, RGB(255, 255, 255), RGB(128, 128, 128));}

8.下面是创建滚动条:

滚动条有不同的通知码，下面是编写各种通知码:

int m_nHScrollPos;//保存水平滚动条的位置。int m_nVScrollPos;//保存垂直滚动条的位置。

//在创建窗口的时候，指定滚动条的位置。m_nHScrollPos = m_nVScrollPos = 0;

int nDelta;switch (nSBCode){case SB_LINEDOWN:nDelta = m_nCellHeight;break;}m_nVScrollPos += nDelta;SetScrollPos(SB_VERT, m_nVScrollPos, TRUE);

#define LINESIZE 8

int nDelta;switch (nSBCode){case SB_LINEUP:nDelta = -LINESIZE;break;case SB_LINEDOWN:nDelta = LINESIZE;break;

int m_nHPageSize;int m_nVPageSize;

int nHScrollMax = 0;//水平可以滚动的最大距离。m_nHPageSize = 0;if (cx < m_nViewWidth){m_nHPageSize = cx;nHScrollMax = m_nViewWidth - 1;}SCROLLINFO si;si.fMask = SIF_PAGE | SIF_RANGE | SIF_POS;si.nMin = 0;si.nMax = nHScrollMax;si.nPos = m_nHScrollPos;si.nPage = m_nHPageSize;SetScrollInfo(SB_HORZ, &si, TRUE);

int nVScrollMax = 0;m_nVPageSize = 0;if (cy < m_nViewHeight){nVScrollMax = m_nViewHeight - 1;m_nVPageSize = cy;}si.fMask = SIF_PAGE | SIF_RANGE | SIF_POS;si.nMin = 0;si.nMax = nVScrollMax;si.nPos = m_nVScrollPos;si.nPage = m_nVPageSize;SetScrollInfo(SB_VERT,&si, TRUE);

效果图:

<span style="white-space:pre"></span>case SB_THUMBTRACK:<span style="white-space:pre"></span>nDelta = (int)nPos - m_nVScrollPos;<span style="white-space:pre"></span>break;    case SB_PAGEUP:<span style="white-space:pre"></span>nDelta = -m_nVPageSize;<span style="white-space:pre"></span>    break;    case SB_PAGEDOWN:<span style="white-space:pre"></span>nDelta = m_nVPageSize;<span style="white-space:pre"></span>    break;<span style="white-space:pre"></span>default:<span style="white-space:pre"></span>return;

下面写水平滚动条:

int nDelta;switch (nSBCode){case SB_LINELEFT:nDelta = -LINESIZE;break;case SB_LINERIGHT:nDelta = LINESIZE;break;case SB_PAGELEFT:nDelta = -m_nHPageSize;break;case SB_PAGERIGHT:nDelta = m_nHPageSize;break;case SB_THUMBTRACK:nDelta = (int)nPos - m_nHScrollPos;break;default:break;}if (nDelta != 0){m_nHScrollPos += nDelta;SetScrollPos(SB_HORZ, m_nHScrollPos, TRUE);}

ScrollWindow(0, -nDelta);

<span style="white-space:pre"></span>dc.SetWindowOrg(m_nHScrollPos, m_nVScrollPos);//图上是错误的。
