            修改控件style的方法

            簡單的說:

            After the control has been created, these styles cannot be modified, except as noted.


            修改控件風格
            ( )

            CWnd* pWnd 為你控件的指針 ,LPCTSTR lpszClassName 是你控件的類名 , 比如編輯框是 "Edit", 按鈕是 "Button", 詳情可以使用 SPY++ 查看 .

            ?

            BOOL ModifyControlStyle(CWnd* pWnd,LPCTSTR lpszClassName,DWORD dwRemove,DWORD dwAdd,DWORD dwRemoveEx,DWORD dwAddEx)

            {

            ?CWnd* pParentWnd = pWnd->GetParent();

            ?

            ?CFont* pFont = pWnd->GetFont();

            ?

            ?CString strText;

            ?pWnd->GetWindowText(strText);

            ?

            ?{

            ? // 在此添加保存控件其他屬性的代碼 , 我只保存了字體和文字

            ?}

            ?

            ?CRect rcWindow;

            ?pWnd->GetWindowRect(&rcWindow);

            ?pParentWnd->ScreenToClient(rcWindow);

            ?

            ?DWORD dwNewStyle = (pWnd->GetStyle() & ~dwRemove) | dwAdd;

            ?DWORD dwNewStyleEx = (pWnd->GetExStyle() & ~dwRemoveEx) | dwAddEx;

            ?

            ?UINT nID = pWnd->GetDlgCtrlID();

            ?

            ?pWnd->ShowWindow(SW_HIDE);

            ?pWnd->DestroyWindow();

            ?

            ?BOOL bResult = pWnd->CreateEx(dwNewStyleEx,lpszClassName,strText,dwNewStyle,rcWindow,pParentWnd,nID);

            ?

            ?pWnd->SetFont(pFont);

            ?

            ?return bResult;

            }

            ?

            測試代碼 :

            ?

            void CAboutDlg::OnButton()

            {

            ?CWnd* pWnd = GetDlgItem(IDC_EDIT1);

            ?

            ?if(pWnd->GetStyle() & ES_PASSWORD)

            ?{

            ? ModifyControlStyle(pWnd,"Edit",ES_PASSWORD,0,0,0);

            ?}

            ?else

            ?{

            ? ModifyControlStyle(pWnd,"Edit",0,ES_PASSWORD,0,0);

            ?}

            }

            ?

            修改控件風格的第二種方法:

            Changing Edit Control Styles at Runtime

            It is not possible to change all the styles of an Edit Control at runtime using ModifyStyle() or ModifyStyleEx(). If you have the need to change the text alignment at runtime, for example, it is best to construct the Edit Control by calling new and CreateEx, then deleting it and creating a new one when the style is to be changed. Alternatively, you can have 2 Edit Controls superimposed and hide the one with the incorrect style.

            ?

            In the demo, I use CreateEx to create the Edit Control, because then the extended style WS_EX_CLIENTEDGE can be used to give the 3D border for the control.

            ?

            ??? m_pFlyEdit->CreateEx(WS_EX_CLIENTEDGE, _T("EDIT"),

            ??????? "", dwStyle, rc, this, IDC_EDIT6);

            You will note the two lines that are commented out. If you enable those and comment out the above line, you will get a flat Edit Control (without border, unless you also uncomment the WS_BORDER style). The control remains flat because WS_EX_CLIENTEDGE is one of the styles that cannot be changed after creation.

            ?

            //??? m_pFlyEdit->Create( dwStyle, rc, this, IDC_EDIT6 );

            //??? m_pFlyEdit->ModifyStyleEx( 0, WS_EX_CLIENTEDGE );

            In the demo, the Edit Controls headed 'Text Alignment test' change the alignment style. The code deletes the old Edit Control and creates a new one each time the radio buttons are clicked. ModifyStyle() is called for m_Edit3 but as you will note, it has no effect.

            ?

            void CEditCtrlTutorialDlg::OnAlignmentChange(UINT nID)

            {

            ??? UpdateData();

            ??? TRACE("CEditCtrlTutorialDlg::OnAlignmentChange( %d )\n",

            ???????????????????????????????????????????????? m_nAlignment);

            ??? DWORD dwStyle =

            ????? WS_CHILD|WS_VISIBLE|WS_TABSTOP/*|WS_BORDER*/|ES_AUTOHSCROLL;

            ?

            ??? switch( m_nAlignment )

            ??? {

            ??? case 1:

            ??????? dwStyle |= ES_CENTER;

            ??????? m_Edit3.ModifyStyle(ES_RIGHT|ES_LEFT,ES_CENTER);

            ??????? break;

            ??? case 2:

            ??????? dwStyle |= ES_RIGHT;

            ??????? m_Edit3.ModifyStyle(ES_CENTER|ES_LEFT,ES_RIGHT);

            ??????? break;

            ??? default:

            ??????? dwStyle |= ES_LEFT;

            ??????? m_Edit3.ModifyStyle(ES_CENTER|ES_RIGHT,ES_LEFT);

            ??????? break;

            ??? }

            ??? m_Edit3.Invalidate();

            ?

            ??? CString str = _T("");

            ??? if( m_pFlyEdit )

            ??? {

            ??????? m_pFlyEdit->GetWindowText( str );

            ??????? delete m_pFlyEdit;

            ??? }

            ?

            ??? CRect rc;

            ??? m_Template.GetWindowRect( &rc );

            ??? ScreenToClient( &rc );

            ??? m_pFlyEdit = new CEdit;

            //??? m_pFlyEdit->Create( dwStyle, rc, this, IDC_EDIT6 );

            //??? m_pFlyEdit->ModifyStyleEx( 0, WS_EX_CLIENTEDGE );

            ??? m_pFlyEdit->CreateEx(WS_EX_CLIENTEDGE, _T("EDIT"),

            ?????????????????????????? "", dwStyle, rc, this, IDC_EDIT6);

            ??? // set font same as dialog to be sure they are the same

            ??? m_pFlyEdit->SetFont( GetFont() );

            ??? m_pFlyEdit->SetWindowText( str );

            ?

            ??? UpdateData(FALSE);

            }

            ES_UPPERCASE and ES_LOWERCASE styles need to be treated in the same way. ES_READONLY style can be changed by calling the SetReadOnly() member function as shown in the demo.

            ?

            void CEditCtrlTutorialDlg::OnReadOnly()

            {

            ??? UpdateData();

            ??? m_Edit2.SetReadOnly( m_bReadOnly );

            }

            The ES_NUMBER style can also be changed at runtime using ModifyStyle(). It is handy where an Edit Control is used for multiple purposes and also to turn the style in case it was forgotten in the RC script. The code below will actually toggle the style:

            ?

            void CEditCtrlTutorialDlg::OnNumbersOnly()

            {

            ??? UpdateData();

            ??? m_Edit7.SetSel(0,-1);??????? // select all the text

            ??? m_Edit7.Clear();??????????? // delete selection

            ??? m_Edit7.ModifyStyle(ES_NUMBER*(m_bNumbersOnly==FALSE),

            ?????????????????????????? ??ES_NUMBER*(m_bNumbersOnly==TRUE));

            }

            In this example, the Edit Control is also cleared while the style is changed. A number-only Edit Control can have non-numeric characters in it. It just won't permit them to be entered from the keyboard.

            ?
