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;
    }
