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();
