100分！win32＋Duilib写视频播放器的，有经验的高手请入。

[maya8maya85]

我的问题不难，但请高手们要给出代码，而不是随便写个函数名，写个宏。如果是这样，分是不会给的。
我想要的效果就一个，全屏与退出全屏。请对win32+duilib了解高手们指导。
现在的情况是：

代码如下：以省去不重要的代码

// 将HWND显示到CControlUI上面
class CWndUI: public CControlUI
{
public:
    CWndUI(): m_hWnd(NULL){}

    virtual void SetVisible(bool bVisible = true)
    {
        __super::SetVisible(bVisible);
        ::ShowWindow(m_hWnd, bVisible);
    }

    virtual void SetInternVisible(bool bVisible = true)
    {
        __super::SetInternVisible(bVisible);
        ::ShowWindow(m_hWnd, bVisible);
    }

    virtual void SetPos(RECT rc,bool bNeedInvalidate = true)
    {
        __super::SetPos(rc);
        ::SetWindowPos(m_hWnd, NULL, rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top, SWP_NOZORDER | SWP_NOACTIVATE);
    }

    BOOL Attach(HWND hWndNew)
    {
        if (! ::IsWindow(hWndNew))
        {
            return FALSE;
        }

        m_hWnd = hWndNew;
        return TRUE;
    }

    HWND Detach()
    {
        HWND hWnd = m_hWnd;
        m_hWnd = NULL;
        return hWnd;
    }

    HWND GetHWND()
    {
        return m_hWnd;
    }

protected:
    HWND m_hWnd;
};

class CDuiPlayFrameWnd : public WindowImplBase
{
	virtual LPCTSTR GetWindowClassName() const { return _T("DUIMainFrame"); }
	virtual CDuiString GetSkinFile() { return _T("PlayWindow.xml"); }
	virtual CDuiString GetSkinFolder() { return _T(""); }
	virtual CControlUI* CreateControl(LPCTSTR pstrClassName)
	{
		if (_tcsicmp(pstrClassName, _T("WndPlayPanel")) == 0)//WndPlayPanel播放控件
		{
			pUI = new CWndUI;
                        //如果加上WS_POPUP能全屏，但是这个子窗口就会不跟随父窗口了
			hWnd = CreateWindow(_T("#32770"), NULL, WS_VISIBLE | WS_CHILD, 0, 0, 0, 0, m_PaintManager.GetPaintWindow(), (HMENU)0, NULL, NULL);
			pUI->Attach(hWnd);
			return pUI;
		}
		return NULL;
	}
	virtual void Notify(TNotifyUI& msg)
	{
		if (msg.sType == _T("click"))
		{
			if (msg.pSender->GetName() == _T("BtnFS"))//点击全屏按钮，下面的代码都是不行的
			{
				///////////////////////////////////////////////////////////////////////////////////////////////////
				//LONG Style = GetWindowLong(hWnd, GWL_STYLE);
				//Style = WS_CHILD | WS_POPUP;
				//SetWindowLong(hWnd, GWL_STYLE, Style);
				////////////////////////////////////////////////////////////////////////////////////////////////////
				//SetWindowLong(hWnd, GWL_STYLE, WS_VISIBLE | WS_MAXIMIZE);//不成功
				//SetWindowLong(hWnd, GWL_STYLE, WS_VISIBLE | WS_POPUP);
				//RECT r;
				//GetWindowRect(m_hWnd, &r);
				//RECT rr;
				//GetWindowRect(hWnd, &rr);
				////////////////////////////////////////////////////////////////////////////////////////////////////
				//SetWindowPos(hWnd, NULL, 0, 0, GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN), SWP_SHOWWINDOW);
				//ShowWindow(hWnd, SW_MAXIMIZE);
				//UpdateWindow(hWnd);
				//////////////////////////////////////////
			}
		}
	}
public:
	CWndUI *pUI;
}

int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
	CPaintManagerUI::SetInstance(hInstance);
	HRESULT Hr = ::CoInitialize(NULL);
	if (FAILED(Hr)) return 0;

	CDuiPlayFrameWnd PlayWindowFrame;
	PlayWindowFrame.Create(NULL, _T("DUISWnd"), UI_WNDSTYLE_FRAME, WS_EX_WINDOWEDGE);
	PlayWindowFrame.CenterWindow();
	PlayWindowFrame.ShowModal();
	
	::CoUninitialize();
	return 0;
}

还有是XML：

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<Window size="720,480" sizebox="4,4,4,4" caption="0,0,0,30" mininfo="720,480">
    <VerticalLayout enabled="true" width="720" height="480">
        <HorizontalLayout enabled="true" height="30" bkimage="file='PlayWindow.png' corner='160,32,0,0'">
            <VerticalLayout enabled="true" height="30" />
            <VerticalLayout enabled="true" width="568" height="30">
				<Button name="BtnFS" float="true" tooltip="全屏" pos="460,5,0,0" width="24" height="22"  align="center" fivestatusimage="file='FS.png'" />   
            </VerticalLayout>
        </HorizontalLayout>
    </VerticalLayout>
</Window>
