MFC 学习之 多对话框及列表控件

MFC 在界面这块，不得不说比较难看，虽然如此，但是它的简洁性（当然，不是说它的代码，而是相对于程序员，减少了自己敲写代码的工作量）。

下面的例子是新建对话框，在新的对话框里添加列表控件，在列表控件里显示必要信息。

效果如图：

新建 MFC 工程，命名为 Draw，添加对话框，新建类 MyPanel

<pre name="code" class="cpp">//CDrawDlg.h

public:
	afx_msg void OnBnClickedBtStart();
	afx_msg void Dlg2_Init();

public:
	MyPanel * panel;

//CDrawDlg.cpp

UINT Func_Thread(LPVOID lpParam)
{
	CDrawDlg * dlg = (CDrawDlg *)lpParam;
	Text_Show(lpParam);
	return 0;
}

void CDrawDlg::OnBnClickedBtStart()
{
	// TODO: 在此添加控件通知处理程序代码
	Dlg2_Init();
	panel->ShowWindow(SW_SHOW);
	AfxBeginThread(Func_Thread, this);
}

void CDrawDlg::Dlg2_Init()
{
	panel->Create(IDD_MY_DIALOG);
}

MyPanel.h

#pragma once
#include "afxcmn.h"

int Text_Show(LPVOID lpParam);
// MyPanel 对话框

class MyPanel : public CDialogEx
{
	DECLARE_DYNAMIC(MyPanel)

public:
	MyPanel(CWnd* pParent = NULL);   // 标准构造函数
	virtual ~MyPanel();

// 对话框数据
	enum { IDD = IDD_MY_DIALOG };

protected:
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV 支持
	//自己添加的，初始化Teechart
	virtual BOOL OnInitDialog();
	DECLARE_MESSAGE_MAP()

public:
	void OnTimer(UINT_PTR nIDEvent);
	void OnCustomdrawMyList ( NMHDR* pNMHDR, LRESULT* pResult );
