duilib教程

首先下载duilib v1.1

打开后用vs2008 运行DuiLib.sln

解决方案窗口中你会发现7个项目分别为 360Safe,DuiLib,FlashDemo,GameDemo,ListDemo,QQDemo,TestApp1

右击360Safe项目 选择 设为启动项目 按Ctrl+F5运行程序, 然后弹出一个小窗口.

现在让我们来分析代码

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE /*hPrevInstance*/, LPSTR /*lpCmdLine*/, int nCmdShow)
{
	CPaintManagerUI::SetInstance(hInstance);//设置实例句柄
	CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath() + _T("skin"));
	CPaintManagerUI::SetResourceZip(_T("360SafeRes.zip"));//设置包含资源的压缩包,里面是图片和要用到的xml

	HRESULT Hr = ::CoInitialize(NULL);//CoInitialize和CoUninitialize必须成对使用。 
	if( FAILED(Hr) ) return 0;//以上代码一般不变

	C360SafeFrameWnd* pFrame = new C360SafeFrameWnd();//初始化实例
	if( pFrame == NULL ) return 0;
	pFrame->Create(NULL, _T("360安全卫士"), UI_WNDSTYLE_FRAME, 0L, 0, 0, 800, 572);//注册类和窗口
	pFrame->CenterWindow();//把窗口放置在中间
	::ShowWindow(*pFrame, SW_SHOW);

	CPaintManagerUI::MessageLoop();//进入消息循环

	::CoUninitialize();
	return 0;
}

然后我们进入 类 C360SafeFrameWnd 中看看

 

class C360SafeFrameWnd : public CWindowWnd, public INotifyUI
{
public:
	C360SafeFrameWnd() { };
	LPCTSTR GetWindowClassName() const { return _T("UIMainFrame"); };
	UINT GetClassStyle() const { return CS_DBLCLKS; };
	void OnFinalMessage(HWND /*hWnd*/) { delete this; };

	void Init() {
		m_pCloseBtn = static_cast<CButtonUI*>(m_pm.FindControl(_T("closebtn")));//得到该按钮对象
		m_pMaxBtn = static_cast<CButtonUI*>(m_pm.FindControl(_T("maxbtn")));//
		m_pRestoreBtn = static_cast<CButtonUI*>(m_pm.FindControl(_T("restorebtn")));//
		m_pMinBtn = static_cast<CButtonUI*>(m_pm.FindControl(_T("minbtn")));//
	}

	void OnPrepare() {//准备代码
	}

	void Notify(TNotifyUI& msg)//消息函数 msg为得到的消息对象
	{
		if( msg.sType == _T("windowinit") ) OnPrepare();//窗口初始化
		else if( msg.sType == _T("click") ) {//点击消息
			if( msg.pSender == m_pCloseBtn ) {
				PostQuitMessage(0);//退出消息

			else if( msg.pSender == m_pRestoreBtn ) {

		}
		else if(msg.sType==_T("setfocus"))//焦点消息
		{
			CStdString name = msg.pSender->GetName();//得到该按钮名字
			CTabLayoutUI* pControl = static_cast<CTabLayoutUI*>(m_pm.FindControl(_T("switch")));
			if(name==_T("examine"))
				 pControl->SelectItem(0);
			else if(name==_T("trojan"))
