Tab control of MFC advanced control (CTabCtrl)

The label control provides a set of label buttons and the display page corresponding to the buttons , Users can click the label button to select different display pages , This different page is actually a different dialog . The header file to use the label control is afxcmn.h, You can add the following code to the header file ：

#include <afxcmn.h>

The following is an example to demonstrate CTabCtrl Control creation , Application of common member functions .

1. newly build MFC Dialog project . Add a... In the dialog box CTabCtrl Control , as follows ：

2. Associate a variable with this price control , as follows ：

 3. In order to make the running program interface look better , Add a... In the dialog box GroupBox Control , And add the previously added CTabCtrl Control to GroupBox Control , And add a button , As shown in the figure below ：

There is a display order on it , If  GroupBox The order of the controls is 1,CTabCtrl Control will be GroupBox Control is overwritten and cannot be displayed .

 4. Insert content In the dialog box OnInitDialog() Add the following code to the function ：

complete  OnInitDialog() The function code is as follows :

BOOL CCTabCtrlTestDlg::OnInitDialog()
{
	CDialogEx::OnInitDialog();

	//  take “ About ...” Menu items are added to the system menu .

	// IDM_ABOUTBOX  Must be within the scope of the system command .
	ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
	ASSERT(IDM_ABOUTBOX < 0xF000);

	CMenu* pSysMenu = GetSystemMenu(FALSE);
	if (pSysMenu != nullptr)
	{
		BOOL bNameValid;
		CString strAboutMenu;
		bNameValid = strAboutMenu.LoadString(IDS_ABOUTBOX);
		ASSERT(bNameValid);
		if (!strAboutMenu.IsEmpty())
		{
			pSysMenu->AppendMenu(MF_SEPARATOR);
			pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
		}
	}

	//  Set the icon for this dialog .   When the application's main window is not a dialog box , The frame will automatically 
	//   Do this 
	SetIcon(m_hIcon, TRUE);			//  Set the big icon 
	SetIcon(m_hIcon, FALSE);		//  Set up small icons 

	// TODO:  Add additional initialization code here 
	m_TabCtrl.InsertItem(0,_T(" The product design "));
	m_TabCtrl.InsertItem(1, _T(" Mold design and manufacturing "));
	m_TabCtrl.InsertItem(2, _T(" Design and manufacture of fixtures and supporting special machines "));
	m_TabCtrl.InsertItem(3, _T(" Sample making and confirmation "));
	m_TabCtrl.InsertItem(4, _T(" Trial production and handover for mass production "));
	m_TabCtrl, ShowWindow(SW_SHOW);
	return TRUE;  //  Unless you set the focus to the control , Otherwise return to  TRUE
}

Start execution without debugging , give the result as follows ：

 5. Design label dialog   Design corresponding dialog boxes respectively , The newly designed dialog box Style Set to child, And add corresponding classes for the dialog . as follows ：

 

 

6. stay CTabCtrlTestDlg.h Contains the header file of the new dialog response class , as follows ：

#include "CPTest.h"
#include "CSample.h"
#include "CMoldDesignAndManufacture.h"
#include "CTMDesignAndManufacture.h"
#include "CDialog_PDesign.h"

7. stay CTabCtrlTestDlg.h Declare variables in , as follows ：

   CDialog_PDesign* pCDialog_PDesign;
    CPTest* pCPTest;
    CSample* pCSample;
    CMoldDesignAndManufacture* pCMoldDesignAndManufacture;
    CTMDesignAndManufacture* pCTMDesignAndManufacture;

8. CTabCtrlTestDlg.cpp Of OnInitDialog() Add the following code to ：

  After adding code OnInitDialog() as follows ：

BOOL CCTabCtrlTestDlg::OnInitDialog()
{
	CDialogEx::OnInitDialog();

	//  take “ About ...” Menu items are added to the system menu .

	// IDM_ABOUTBOX  Must be within the scope of the system command .
	ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
	ASSERT(IDM_ABOUTBOX < 0xF000);

	CMenu* pSysMenu = GetSystemMenu(FALSE);
	if (pSysMenu != nullptr)
	{
		BOOL bNameValid;
		CString strAboutMenu;
		bNameValid = strAboutMenu.LoadString(IDS_ABOUTBOX);
		ASSERT(bNameValid);
		if (!strAboutMenu.IsEmpty())
		{
			pSysMenu->AppendMenu(MF_SEPARATOR);
			pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
		}
	}

	//  Set the icon for this dialog .   When the application's main window is not a dialog box , The frame will automatically 
	//   Do this 
	SetIcon(m_hIcon, TRUE);			//  Set the big icon 
	SetIcon(m_hIcon, FALSE);		//  Set up small icons 

	// TODO:  Add additional initialization code here 
	m_TabCtrl.InsertItem(0,_T(" The product design "));
	m_TabCtrl.InsertItem(1, _T(" Mold design and manufacturing "));
	m_TabCtrl.InsertItem(2, _T(" Design and manufacture of fixtures and supporting special machines "));
	m_TabCtrl.InsertItem(3, _T(" Sample making and confirmation "));
	m_TabCtrl.InsertItem(4, _T(" Trial production and handover for mass production "));
	pCDialog_PDesign = new CDialog_PDesign();
	pCDialog_PDesign->Create(IDD_DIALOG_PDESIGN,&m_TabCtrl);
	pCPTest = new CPTest();
	pCPTest->Create(IDD_DIALOG_PTEST, &m_TabCtrl);
	pCSample = new CSample();
	pCSample->Create(IDD_DIALOG_SAMPLING, &m_TabCtrl);
	pCMoldDesignAndManufacture = new CMoldDesignAndManufacture();
	pCMoldDesignAndManufacture->Create(IDD_DIALOG_MOLDDM, &m_TabCtrl);
	pCTMDesignAndManufacture = new CTMDesignAndManufacture();
	pCTMDesignAndManufacture->Create(IDD_DIALOG_TMDM, &m_TabCtrl);
	pCDialog_PDesign->CenterWindow();
	pCDialog_PDesign->ShowWindow(SW_SHOW);
	
	return TRUE;  //  Unless you set the focus to the control , Otherwise return to  TRUE
}

 9. For in conversation CTabCtrl Controls to add OnTcnSelchange Message handler , as follows ：

void CCTabCtrlTestDlg::OnTcnSelchangeTab1(NMHDR *pNMHDR, LRESULT *pResult)
{
	// TODO:  Add control notification handler code here 
	int mSel = m_TabCtrl.GetCurSel();
	switch (mSel)
	{
	case 0:
		pCDialog_PDesign->CenterWindow();
		pCDialog_PDesign->ShowWindow(SW_SHOW);
		pCPTest-> ShowWindow(SW_HIDE);
		pCSample-> ShowWindow(SW_HIDE);
		pCMoldDesignAndManufacture-> ShowWindow(SW_HIDE);
		pCTMDesignAndManufacture-> ShowWindow(SW_HIDE);
		break;
	case 1:
		pCDialog_PDesign->ShowWindow(SW_HIDE);
		pCPTest->ShowWindow(SW_HIDE);
		pCSample->ShowWindow(SW_HIDE);
		pCMoldDesignAndManufacture->CenterWindow();
		pCMoldDesignAndManufacture->ShowWindow(SW_SHOW);
		pCTMDesignAndManufacture->ShowWindow(SW_HIDE);
		break;
	case 2:
		pCDialog_PDesign->ShowWindow(SW_HIDE);
		pCPTest->ShowWindow(SW_HIDE);
		pCSample->ShowWindow(SW_HIDE);
		pCMoldDesignAndManufacture->ShowWindow(SW_HIDE);
		pCTMDesignAndManufacture->CenterWindow();
		pCTMDesignAndManufacture->ShowWindow(SW_SHOW);
		break;
	case 3:
		pCDialog_PDesign->ShowWindow(SW_HIDE);
		pCPTest->ShowWindow(SW_HIDE);
		pCSample->CenterWindow();
		pCSample->ShowWindow(SW_SHOW);
		pCMoldDesignAndManufacture->ShowWindow(SW_HIDE);
		pCTMDesignAndManufacture->ShowWindow(SW_HIDE);
		break;
	case 4:
		pCDialog_PDesign->ShowWindow(SW_HIDE);
		pCPTest->CenterWindow();
		pCPTest->ShowWindow(SW_SHOW);
		pCSample->ShowWindow(SW_HIDE);
		pCMoldDesignAndManufacture->ShowWindow(SW_HIDE);
		pCTMDesignAndManufacture->ShowWindow(SW_HIDE);
		break;
	default:
		pCDialog_PDesign->CenterWindow();
		pCDialog_PDesign->ShowWindow(SW_SHOW);
		pCPTest->ShowWindow(SW_HIDE);
		pCSample->ShowWindow(SW_HIDE);
		pCMoldDesignAndManufacture->ShowWindow(SW_HIDE);
		pCTMDesignAndManufacture->ShowWindow(SW_HIDE);
		break;
	}
	*pResult = 0;
}

Execution procedure （ Don't debugging ）, give the result as follows ：

  Click on “ Mold design and manufacturing ”, give the result as follows ：

  Here is a complete demonstration CTabCtrl( label ) Control creation process , The implementation in the dialog box is not completed .
