MFC编程Tab控件的使用

MFC编程实例一
MFC标签控件的使用
首先添加TabSheet类，菜单Insert->New Class
在弹出的对话框中类名写TabSheet，基类选择TabCtrl
TabSheet.h里面CTabSheet window用如下代码替换：
#define MAXPAGE 16
class CTabSheet : public CTabCtrl
{
// Construction
public:
CTabSheet();
// Attributes
public:
// Operations
public:
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CTabSheet)
//}}AFX_VIRTUAL
// Implementation
public:
int GetCurSel();
int SetCurSel(int nItem);
void Show();
void SetRect();
BOOL AddPage(LPCTSTR title, CDialog *pDialog, UINT ID);
virtual ~CTabSheet();
// Generated message map functions
protected:
LPCTSTR m_Title[MAXPAGE];
UINT m_IDD[MAXPAGE];
CDialog* m_pPages[MAXPAGE];
int m_nNumOfPages;
int m_nCurrentPage;
//{{AFX_MSG(CTabSheet)
afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
///////////////////////////////////////////////////////////////////// ////////
//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.
#endif
// !defined(AFX_TABSHEET_H__42EE262D_D15F_46D5_8F26_28FD049E99F4__INC LUDED_)
TabSheet.cpp里面TabSheet后面用如下代码替换：
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( 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();
}
///////////////////////////////////////////////////////////////////// ////////
// CTabSheet
添加Tab控件，设置变量m_tab的类型为TabSheet
新建两个对话框，CStudent和CClassDlg,对话框内容根据需要自己设计。

将这两个对话框属性设置为：styles选项卡里面style选择child,然后将title bar复选框勾选删掉
tabDlg.h文件里面添加
#include "TabSheet.h"
#include "Student.h"//标签里面要显示的对话框类
#include "ClassDlg.h"
在class tabDlg里面添加private成员并声明要显示的对话框的一个对象，即private:
CStudent dlg;
ClassDlg dlg2;
最后在tabDlg.cpp初始化函数中添加如下代码即可
m_tab.AddPage("班级成绩", &dlg, IDD_DIALOG1);
m_tab.AddPage("年级成绩", &dlg2, IDD_DIALOG2);
m_tab.Show();
运行结果:。
