WTL CTabCtrl 使用实例

WTL CTabCtrl 使用实例
假设基于对话框界面开发， 实现一组Tab页面。

在 .H  文件中，对类及成员的定义如下：

对话框子类继承：

class CMyMainDlg :  public CDialogImpl<CMyMainDlg>,public CWinDataExchange<CMyMainDlg>

消息映射：

BEGIN_MSG_MAP_EX(CMyMainDlg)MSG_WM_INITDIALOG(OnInitDialog)MESSAGE_HANDLER(WM_SYSCOMMAND, OnSysCommand)NOTIFY_HANDLER_EX(IDC_TAB1, TCN_SELCHANGE, OnSelchangeTab1)END_MSG_MAP()

响应函数声明：

LRESULT OnSelchangeTab1(LPNMHDR pnmh);

定义类成员变量：
界面上，放置有4个Tab页面：

CDialogImpl* m_pFunctionDlg[4];int m_CurSelTabIndex;CTabCtrlm_tab;

在源文件中，增加TabCtrl变量的初始化、点击响应过程如下：

BOOL CMyMainDlg::OnInitDialog(CWindow wndFocus, LPARAM lInitParam){m_tab = GetDlgItem(IDC_TAB1);    TCITEM t1;t1.mask = TCIF_TEXT;t1.pszText = (LPTSTR)“1”;//_T("完整性检查");    m_tab.InsertItem(0, &t1);    m_Dlg1.Create(m_tab.m_hWnd);    m_pFunctionDlg[0] = (CDialogImpl *)&m_Dlg1;    m_pFunctionDlg[0]->MoveWindow(&rc);    m_pFunctionDlg[0]->ShowWindow(SW_SHOW);    TCITEM t2;t2.mask = TCIF_TEXT;t2.pszText = (LPTSTR)“2”;m_tab.InsertItem(1, &t2);m_Dlg2.Create(m_tab.m_hWnd);m_pFunctionDlg[1] = (CDialogImpl *)&m_Dlg2;m_pFunctionDlg[1]->MoveWindow(&rc);m_pFunctionDlg[1]->ShowWindow(SW_HIDE);    TCITEM t3;t3.mask = TCIF_TEXT;t3.pszText = (LPTSTR)“3”;m_tab.InsertItem(2, &t3);m_Dlg3.Create(m_tab.m_hWnd);m_pFunctionDlg[2] = (CDialogImpl *)&m_Dlg3;m_pFunctionDlg[2]->MoveWindow(&rc);m_pFunctionDlg[2]->ShowWindow(SW_HIDE);TCITEM t3;t3.mask = TCIF_TEXT;t3.pszText = (LPTSTR)“3”;m_tab.InsertItem(3, &t3);m_Dlg3.Create(m_tab.m_hWnd);m_pFunctionDlg[3] = (CDialogImpl *)&m_Dlg3;m_pFunctionDlg[3]->MoveWindow(&rc);m_pFunctionDlg[3]->ShowWindow(SW_HIDE);m_CurSelTabIndex = 0;return TRUE;  // return TRUE unless you set the focus to a control}LRESULT CMyMainDlg::OnSelchangeTab1(LPNMHDR pnmh){m_pFunctionDlg[m_CurSelTabIndex]->ShowWindow(SW_HIDE);m_CurSelTabIndex = m_tab.GetCurSel();m_pFunctionDlg[m_CurSelTabIndex]->ShowWindow(SW_SHOW);return 0;}
