WTL-Aero,DWM,GDI

Windows 7系统自带一个小附件程序，叫做Windows Mobility Center:

这个小程序在整个Aero界面上添加了几个“区块”，每个区块上有一些系统内置控件。

我尝试着用WTL编写一个类似风格的窗口，实现了一部分功能：

 

实现代码：

class CAeroButton :

    public CAeroControlImpl<CAeroButton,CButton>

{

public:

    DECLARE_WND_SUPERCLASS(_T("WTL Aero Button"),GetWndClassName())

    typedef CAeroControlImpl<CAeroButton,CButton> _baseAeroCtrl;

    BEGIN_MSG_MAP(CAeroButton)

        CHAIN_MSG_MAP(_baseAeroCtrl)

    END_MSG_MAP()

};

class CAeroStatic :

    public CAeroControlImpl<CAeroStatic,CStatic>

{

public:

    DECLARE_WND_SUPERCLASS(_T("WTL Aero Static"),GetWndClassName())

    typedef CAeroControlImpl<CAeroStatic,CStatic> _baseAeroCtrl;

    BEGIN_MSG_MAP(CAeroStatic)

        MSG_WM_CREATE(OnCreate)

        MSG_OCM_CTLCOLORSTATIC(OnCtlColorStatic)

        CHAIN_MSG_MAP(_baseAeroCtrl)

    END_MSG_MAP()

    int OnCreate(LPCREATESTRUCT /*lpCreateStruct*/)

    {

        m_BkgndBrush.CreateSysColorBrush(COLOR_WINDOW);

        return 0;

    }

    HBRUSH OnCtlColorStatic(CDCHandle /*dc*/, CStatic /*wndStatic*/)

    {

        return m_BkgndBrush;

    }

private:

    CBrush m_BkgndBrush;

};

class CAeroComboBox :

    public CAeroControlImpl<CAeroComboBox,CComboBox>

{

public:

    DECLARE_WND_SUPERCLASS(_T("WTL Aero ComboBox"),GetWndClassName())

    typedef CAeroControlImpl<CAeroComboBox,CComboBox> _baseAeroCtrl;

    BEGIN_MSG_MAP(CAeroComboBox)

        REFLECTED_COMMAND_CODE_HANDLER_EX(CBN_DROPDOWN,OnDropDown)

        CHAIN_MSG_MAP(_baseAeroCtrl)

    END_MSG_MAP()

    LRESULT OnDropDown(UINT /*uNotifyCode*/, int /*nID*/, CWindow /*wndCtl*/)

    {

        DefWindowProc();

        InvalidateRect(NULL,FALSE);

        return 0;

    }

};

enum

{

    IDC_AERO_BUTTON = 1001,

    IDC_AERO_STATIC,

    IDC_AERO_COMBOBOX

};

class CClientView :

    public CAeroControlImpl<CClientView>

{

public:

    DECLARE_WND_CLASS(_T("WTL client view"))

    typedef CAeroControlImpl<CClientView> _baseAeroCtrl;

    BEGIN_MSG_MAP(CClientView)

        MSG_WM_CREATE(OnCreate)

        REFLECT_NOTIFICATIONS_EX()

        CHAIN_MSG_MAP(_baseAeroCtrl)

    END_MSG_MAP()

public:

    int OnCreate(LPCREATESTRUCT /*lpCreateStruct*/)

    {

        CLogFont lf;

        TCHAR fontName[] = _T("Courier New");

        _tcscpy_s(lf.lfFaceName,fontName);

        lf.lfHeight = 40;

        m_TextFont.CreateFontIndirect(&lf);

        m_GuiFont = AtlGetDefaultGuiFont();

        CRect rc(10,10,130,50);
