MFC tabcontrol切换界面

article/2025/10/10 0:17:36

1.添加控件tabcontrol。

2.切换到资源界面->Dialog->插入Dialog，创建两个Dialog界面。

3.为新建的两个Dialog添加类，在新建的Dialog界面右键类向导添加对应的类。

4.添加TabSheet.cpp 和TabSheet.h 这两个文件从网上下载即可，具体源码如下：

TabSheet.cpp：

// TabSheet.cpp : implementation file  
#include "stdafx.h"  
#include "TabSheet.h"  
#ifdef _DEBUG  
#define new DEBUG_NEW  
#undef THIS_FILE  
static char THIS_FILE[] = __FILE__;  
#endif  
/  
// CTabSheet  
CTabSheet::CTabSheet()  
{  m_nNumOfPages = 0;  m_nCurrentPage = 0;  
}  CTabSheet::~CTabSheet()  
{  
}  BEGIN_MESSAGE_MAP(CTabSheet, CTabCtrl)  //{{AFX_MSG_MAP(CTabSheet)  ON_WM_LBUTTONDOWN()  //}}AFX_MSG_MAP  
END_MESSAGE_MAP()  /  
// CTabSheet message handlers  BOOL CTabSheet::AddPage(LPCTSTR title, CDialog *pDialog,UINT ID)  
{  if( MAXPAGE == m_nNumOfPages )  return FALSE;  m_nNumOfPages++;  m_pPages[m_nNumOfPages-1] = pDialog;  m_IDD[m_nNumOfPages-1] = ID;  m_Title[m_nNumOfPages-1] = title;  return TRUE;  
}  void CTabSheet::SetRect()  
{  CRect tabRect, itemRect;  int nX, nY, nXc, nYc;  GetClientRect(&tabRect);  GetItemRect(0, &itemRect);  nX=itemRect.left;  nY=itemRect.bottom+1;  nXc=tabRect.right-itemRect.left-2;  nYc=tabRect.bottom-nY-2;  m_pPages[0]->SetWindowPos(&wndTop, nX, nY, nXc, nYc, SWP_SHOWWINDOW);  for( int nCount=1; nCount < m_nNumOfPages; nCount++ )  m_pPages[nCount]->SetWindowPos(&wndTop, nX, nY, nXc, nYc, SWP_HIDEWINDOW);  }  void CTabSheet::Show()  
{  for( int i=0; i < m_nNumOfPages; i++ )  {  m_pPages[i]->Create( m_IDD[i], this );  InsertItem( i, m_Title[i] );  }  m_pPages[0]->ShowWindow(SW_SHOW);  for( int i=1; i < m_nNumOfPages; i++)  m_pPages[i]->ShowWindow(SW_HIDE);  SetRect();  }  void CTabSheet::OnLButtonDown(UINT nFlags, CPoint point)   
{  CTabCtrl::OnLButtonDown(nFlags, point);  if(m_nCurrentPage != GetCurFocus())  {  m_pPages[m_nCurrentPage]->ShowWindow(SW_HIDE);  m_nCurrentPage=GetCurFocus();  m_pPages[m_nCurrentPage]->ShowWindow(SW_SHOW);  //      m_pPages[m_nCurrentPage]->SetFocus();  }  
}  int CTabSheet::SetCurSel(int nItem)  
{  if( nItem < 0 || nItem >= m_nNumOfPages)  return -1;  int ret = m_nCurrentPage;  if(m_nCurrentPage != nItem )  {  m_pPages[m_nCurrentPage]->ShowWindow(SW_HIDE);  m_nCurrentPage = nItem;  m_pPages[m_nCurrentPage]->ShowWindow(SW_SHOW);  //      m_pPages[m_nCurrentPage]->SetFocus();  CTabCtrl::SetCurSel(nItem);  }  return ret;  
}  int CTabSheet::GetCurSel()  
{  return CTabCtrl::GetCurSel();  
} //释放page资源
void CTabSheet::Free()
{CTabCtrl::DeleteAllItems();for( int i=0; i < m_nNumOfPages; i++ )  {  m_pPages[i]->DestroyWindow();m_IDD[i] = NULL;m_Title[i] = NULL;}  m_nCurrentPage = 0;m_nNumOfPages = 0;//CTabCtrl::DestroyWindow();  //注意不要将this指针释放了
}

TabSheet.h

#if !defined(AFX_TABSHEET_H__42EE262D_D15F_46D5_8F26_28FD049E99F4__INCLUDED_)

5.将TabSheet.cpp和TabSheet.h添加到工程中。
