DuiLib（3）——DuiLib与MFC嵌套攻略

一、做一个duilib公共头文件

#pragma once
#include <UIlib.h>
using namespace DuiLib;

#ifdef _DEBUG
#   ifdef _UNICODE
#       pragma comment(lib, "DuiLib_ud.lib")
#   else
#       pragma comment(lib, "DuiLib_d.lib")
#   endif
#else
#   ifdef _UNICODE
#       pragma comment(lib, "DuiLib_u.lib")
#   else
#       pragma comment(lib, "DuiLib.lib")
#   endif
#endif


// 以XML生成界面的窗口基类
class CXMLWnd : public WindowImplBase
{
public:
    explicit CXMLWnd(LPCTSTR pszXMLPath) 
        : m_strXMLPath(pszXMLPath)
	{}

public:
    virtual LPCTSTR GetWindowClassName() const
    {
        return _T("XMLWnd");
    }

    virtual CDuiString GetSkinFile()
    {
        return m_strXMLPath;
    }

    virtual CDuiString GetSkinFolder()
    {
        return _T("");
    }

protected:
    CDuiString m_strXMLPath;
};


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

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

    virtual void SetPos(RECT rc, bool bNeedInvalidate)
    {
        __super::SetPos(rc, bNeedInvalidate);
        ::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;
    }

protected:
    HWND m_hWnd;
};

二、MFC中的对话框，作为一个自定义控件，放到duilib界面上

头文件DuiFrameWnd.h

#pragma once
#include "duilib.h"
#include "MyDlg.h"
#include "resource.h"
class CDuiFrameWnd :
	public CXMLWnd
{
public:
	explicit CDuiFrameWnd(const CString& strXmlPath, CMyDlg* pDlgMain = NULL);
	~CDuiFrameWnd();
private: 
	virtual void Notify(TNotifyUI& msg);
	virtual void OnFinalMessage(HWND hWnd);
	virtual CControlUI* CreateControl(LPCTSTR pstrClassName);
	virtual LRESULT HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam);
protected:
	CMyDlg* m_pDlgMain; // 主对话框，所有的消息处理都交给他
	vector<CWnd *> m_btn; // 收集所有的指针，方便最后销毁
};

源文件DuiFrameWnd.cpp

#include "stdafx.h"
#include "DuiFrameWnd.h"
#define IDC_BUTTON_DUI_NEXT 2000
CDuiFrameWnd::CDuiFrameWnd(const CString& strXmlPath, CMyDlg* pDlgMain)
	: CXMLWnd(strXmlPath),m_pDlgMain(pDlgMain)
{
	CPaintManagerUI::SetInstance(AfxGetInstanceHandle());                    // 指定duilib的实例
	CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath());    // 指定duilib资源的路径，这里指定为和exe同目录
}

CDuiFrameWnd::~CDuiFrameWnd()
{}
void CDuiFrameWnd::OnFinalMessage(HWND hWnd)
{
	if (!m_btn.empty()) {
		for (auto* e : m_btn)
		{
			if (e != NULL) {
				delete e;
				e = NULL;
			}
		}
	}
	delete this;
}
void CDuiFrameWnd::Notify(TNotifyUI& msg)
{
	if (msg.sType == _T("click"))
	{
		if (msg.pSender->GetName() == _T("btn"))
		{
			if (m_pDlgMain != NULL) {
				/*转移到m_pDlgMain中处理*/
			}
		}
	}
	__super::Notify(msg);
}
CControlUI* CDuiFrameWnd::CreateControl(LPCTSTR pstrClassName) 
{
	if (_tcsicmp(pstrClassName, _T("Wnd")) == 0)
	{
		CWndUI *pUI = new CWndUI;
		CButton * btn = new CButton;
		btn->Create(_T("MFC"), WS_VISIBLE | WS_CHILD | BS_PUSHBUTTON, CRect(0, 0, 0,0), CWnd::FromHandle(m_PaintManager.GetPaintWindow()), IDC_BUTTON_DUI_NEXT);
		pUI->Attach(btn->GetSafeHwnd());
		m_btn.push_back(btn);
		return pUI;
	}
	else if (_tcsicmp(pstrClassName, _T("Dialog")) == 0)
	{
		CWndUI  *pUI = new CWndUI;
		CMyDlg* m_pDlg = new CMyDlg;
		m_pDlg->Create(IDD_DIALOG1);
		pUI->Attach(m_pDlg->GetSafeHwnd());
		m_pDlgMain = m_pDlg;
		m_btn.push_back(m_pDlgMain);
		return pUI;
	}
	return NULL;
}
LRESULT CDuiFrameWnd::HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam) 
{
	switch (uMsg)
	{
	case WM_COMMAND: {
		if (IDC_BUTTON_DUI_NEXT == wParam) {
			if (m_pDlgMain != NULL) {
				/*转移到m_pDlgMain中处理*/
			}
		}
		break;
	}
	default:
		break;
	}
	return __super::HandleMessage(uMsg, wParam, lParam);
}

三、在MFC中的app里初始化duilib对话框

	CDuiFrameWnd *pFrame = new CDuiFrameWnd(_T("skin.xml"));
	m_pMainWnd = CWnd::FromHandle(*pFrame);

	pFrame->Create(NULL, _T("DUIWnd"), UI_WNDSTYLE_FRAME, WS_EX_WINDOWEDGE);
	pFrame->CenterWindow();
	INT_PTR nResponse = pFrame->ShowModal();
