duilib的通用窗口类WindowImplBase

前言

duilib程序中，编写自己的窗口类一般的继承关系有两种，一种是继承自CWindowWnd、INotifyUI、IMessageFilterUI，而第二种方式是继承自duilib封装好的通用窗口类WindowImplBase

WindowImplBase类

从源码中可以看到WindowImplBase其实是继承自一般能用到的所有基础类：

class DUILIB_API WindowImplBase
		: public CWindowWnd
		, public CNotifyPump
		, public INotifyUI
		, public IMessageFilterUI
		, public IDialogBuilderCallback

优点

从上可以看到，一般编写自己的duilib窗口类所需要继承的几个类都已经被WindowImplBase继承了，而且已经做了部分封装，这样我们直接继承WindowImplBase不是方便了很多，而且只需要实现以下几个函数即可实现简单的duilib窗口，很简洁方便

virtual CDuiString GetSkinFolder() = 0;
virtual CDuiString GetSkinFile() = 0;
virtual LPCTSTR GetWindowClassName(void) const = 0 ;

缺点

WindowImplBase通用窗口类目前不完全统计bug较多，好多地方需要自己修改，这个就要根据自己的需求不同自己去调整该类的源码，达到自己想要的效果。

示例

下面实现一个简单的例子：

MainFrame.h

#include "resource.h"
class CMainFrame : public WindowImplBase
{
public:
	CMainFrame();
	~CMainFrame();
public:
	LPCTSTR GetWindowClassName() const;
	virtual CDuiString GetSkinFile();
	virtual CDuiString GetSkinFolder();
	
	virtual LRESULT HandleCustomMessage(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
	virtual LRESULT HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam);
	
public:
	
protected:
	void Notify(TNotifyUI& msg);
	bool OnBtnClickOfEnter(TNotifyUI& msg);
};

MainFrame.cpp

#include "stdafx.h"
#include "MainFrame.h"
#include "DefControlName.h"
#include "PersonalCenterDialog.h"
HWND g_hMainFrame = NULL;

CMainFrame::CMainFrame()
{
}

CMainFrame::~CMainFrame()
{
	PostQuitMessage(0);
}

LPCTSTR CMainFrame::GetWindowClassName() const
{
	return _T("App");
}

CDuiString CMainFrame::GetSkinFile()
{
	return _T("MainFrame.xml");
}

CDuiString CMainFrame::GetSkinFolder()
{
	return  _T("skin\\");
}

//duilib自身消息
void CMainFrame::Notify(TNotifyUI& msg)
{
	if (_tcsicmp(msg.sType, _T("windowinit")) == 0)
	{
		
	}
	else if (_tcsicmp(msg.sType, _T("killfocus")) == 0)
	{

	}
	else if (_tcsicmp(msg.sType, _T("click")) == 0)
	{
		if (_tcsicmp(msg.pSender->GetName(), kMainFrameBtnClose) == 0)
		{
			Close();
		}
		else if (_tcsicmp(msg.pSender->GetName(), kMainFrameBtnEnter) == 0)
		{
			OnBtnClickOfEnter(msg);
		}
	}
	else if (_tcsicmp(msg.sType, _T("timer")) == 0)
	{ }
	else if (_tcsicmp(msg.sType, _T("selectchanged")) == 0)
	{ }
	else if (_tcsicmp(msg.sType, _T("itemactivate")) == 0)
	{ }
	else if (_tcsicmp(msg.sType, _T("itemclick")) == 0)
	{ }
}

bool CMainFrame::OnBtnClickOfEnter(TNotifyUI & msg)
{
	CPersonalCenterDialog* pDialog = new CPersonalCenterDialog();
	if (pDialog == NULL)
		return false;

	DWORD dwStyle = UI_WNDSTYLE_FRAME;
	dwStyle = dwStyle^WS_MAXIMIZEBOX;
#if defined(WIN32) && !defined(UNDER_CE)
	pDialog->Create(NULL, _T("个人中心"), dwStyle | WS_POPUP, NULL, 0, 0, 0, 0);
#else
	pDialog->Create(NULL, _T("个人中心"), dwStyle | WS_POPUP, NULL, 0, 0, 0, 0);
#endif

	pDialog->CenterWindow();
	::ShowWindow(g_hMainFrame, SW_HIDE);
	::ShowWindow(*pDialog, SW_SHOW);

	return true;

}

//处理自定义消息
LRESULT CMainFrame::HandleCustomMessage(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
	switch (uMsg)
	{
	/*case WM_APPOBD_MSG_SHOW_MAIN_FRAME:
	{
		::ShowWindow(m_hWnd, SW_SHOW);
		break;
	}*/
	default:
		break;
	}

	return 0;
}

//处理事件消息
LRESULT CMainFrame::HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	switch (uMsg)
	{
	case WM_DEVICECHANGE:
	{
		break;
	}
	//case WM_CLOSE:
	//	PostQuitMessage(0);
	//	break;
	default:
		break;
	}

	return WindowImplBase::HandleMessage(uMsg, wParam, lParam);
}
