Windows Explorer Application

Introduction

A tree explorer is the type of application that displays a tree control on one side and another type of control on another side of a main window. Many applications nowadays use this scenario. Windows Explorer, although not the only one, is the most popular of them:

In Windows Explorer, a tree control displays on the left side and a list control on the right side. In some other applications, the tree may be positioned to the top, the right, the bottom, or a corner of the parent window.

When the user clicks an item in the tree, another view changes to display items that are related to the tree. There are no preset rules as to what to display or what kind of item to display. Everything depends on the person or the company that created the application.

The Tree Explorer in MFC Applications

Because of the complexities of the document/view architecture, the MFC probably doesn't provide the least difficult approach to creating a tree explorer. In an MFC application, you usually have to involve each view around the document class in order to get the necessary functionality. For example, if you plan to create an object like Windows Explorer, you may want to use a CTreeView object on the left side and a CListView on the right side. To implement their functionality, that is, to get information to flow from one view to another, you would consider a CDocument variable as the central object.
 
 

Practical Learning: Starting the Exercise
  1. Start Microsoft Visual C++
  2. Create a new project using MFC AppWizard or as an MFC Application
  3. Name it Championships
  4. Create the project as a Single Document
  5. Click the Windows Explorer radio button
     
  6. Change the file names in the dialog box as follows:
     
      Class Name Header File Implementation File Base Class
    CChampionshipsView CRightView RightView.h RightView.cpp CListView
    CChampionshipsApp CExerciseApp No Change No Change No Change
    CChampionshipsDoc CExerciseDoc ExerciseDoc.h ExerciseDoc.cpp No Change
    CLeftView No Change No Change No Change No Change
  7. Click Finish
     
  8. In the Class View, double-click CLeftView and notice that is has a method called GetDocument() that returns a CExerciseDoc pointer
  9. In the Class View, double-click CRightView and notice that is has a method called GetDocument() that returns a CExerciseDoc pointer
    This means that the document class will plan as the intermediary between the views. Now you need to let the document class know about the view classes
  10. In Class View, double-click CExerciseDoc to access its header file
  11. Declare a pointer to each view class as follows:
      
    // ExerciseDoc.h : interface of the CExerciseDoc class
//
/////////////////////////////////////////////////////////////////////////////

#pragma once

class CLeftView;
class CRightView;

class CExerciseDoc : public CDocument
{
protected: // create from serialization only
	CExerciseDoc();
	DECLARE_DYNCREATE(CExerciseDoc)

// Attributes
public:

// Operations
public:
	CLeftView  *pLeftView;
	CRightView *pRightView;

// Overrides
	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CExerciseDoc)
	public:
	virtual BOOL OnNewDocument();
	virtual void Serialize(CArchive& ar);
	//}}AFX_VIRTUAL

// Implementation
public:
	virtual ~CExerciseDoc();
#ifdef _DEBUG
	virtual void AssertValid() const;
	virtual void Dump(CDumpContext& dc) const;
#endif

protected:

// Generated message map functions
protected:
	//{{AFX_MSG(CExerciseDoc)
	//}}AFX_MSG
	DECLARE_MESSAGE_MAP()
};
  12. Using the ClassWizard dialog box or the Properties window, generate the WM_CREATE message of the CLeftView class
     
  13. Whenever a view goes through the document class to access the left view, you need to communicate to the document view what object is being called. To indicate this, implement the OnCreate() event as follows:
      
    int CLeftView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
	if (CTreeView::OnCreate(lpCreateStruct) == -1)
		return -1;
	
	// TODO: Add your specialized creation code here
	GetDocument()->pLeftView = this;

	return 0;
}
  14. Using the ClassWizard dialog box or the Properties window, generate the WM_CREATE message of the CLeftView class
  15. Whenever a view goes through the document class to access the right view, you need to communicate to the document view what object is being called. To indicate this, implement the OnCreate() event as follows:
      
    int CRightView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
	if (CListView::OnCreate(lpCreateStruct) == -1)
		return -1;
	
	// TODO: Add your specialized creation code here
	GetDocument()->pRightView = this;

	return 0;
}
  16. On the main menu, click Insert -> Resource...
  17. In the Insert Resource dialog box, double-click Bitmap
  18. Change the ID of the bitmap to IDB_TREE_BMP
  19. Set its Width to 96
  20. Set its Height to 16
  21. Design the bitmap as follows:
     
  22. In the header file of the CLeftView class, declare a CImageList variable named:
      
    #pragma once

class CExerciseDoc;

class CLeftView : public CTreeView
{
protected: // create from serialization only
	CLeftView();
	DECLARE_DYNCREATE(CLeftView)

// Attributes
public:
	CExerciseDoc* GetDocument();

// Operations
public:
	CImageList m_TreeImages;

// Overrides
	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CLeftView)
	public:
	virtual void OnDraw(CDC* pDC);  // overridden to draw this view
	virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
	protected:
	virtual BOOL OnPreparePrinting(CPrintInfo* pInfo);
	virtual void OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo);
	virtual void OnEndPrinting(CDC* pDC, CPrintInfo* pInfo);
	virtual void OnInitialUpdate(); // called first time after construct
	//}}AFX_VIRTUAL

// Implementation
public:
	virtual ~CLeftView();
#ifdef _DEBUG
	virtual void AssertValid() const;
	virtual void Dump(CDumpContext& dc) const;
#endif

protected:

// Generated message map functions
protected:
	//{{AFX_MSG(CLeftView)
	afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
	//}}AFX_MSG
	DECLARE_MESSAGE_MAP()
};

#ifndef _DEBUG  // debug version in LeftView.cpp
inline CExerciseDoc* CLeftView::GetDocument()
   { return (CExerciseDoc*)m_pDocument; }
#endif
  23. To create some items for the tree, in Class View, right-click CLeftView -> Add Member Function...
  24. Set the return type to void
  25. Set the Function Name to CreateLeagues
     
  26. Press Enter and implement the method as follows:
      
    void CLeftView::CreateLeagues()
{
	// If there is anything in the tree, remove it
	GetTreeCtrl().DeleteAllItems();

	CTreeCtrl &ctlLeagues = this->GetTreeCtrl();
	m_TreeImages.Create(IDB_TREE_BMP, 16, 1, RGB(255, 255, 255));

	ctlLeagues.SetImageList(&m_TreeImages, TVSIL_NORMAL);

	HTREEITEM hRoot;
	HTREEITEM hSeason;

	hRoot = ctlLeagues.InsertItem(_T("World Football Championships"), 0, 1);

	hSeason = ctlLeagues.InsertItem("English Premier League", 2, 3, hRoot);
	ctlLeagues.InsertItem(_T("2004-2005"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2003-2004"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2002-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2000-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("1999-2000"), 4, 5, hSeason);

	hSeason = ctlLeagues.InsertItem("Lega Nazionale Professionisti", 2, 3, hRoot);
	ctlLeagues.InsertItem(_T("2004-2005"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2003-2004"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2002-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2000-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("1999-2000"), 4, 5, hSeason);
	
	hSeason = ctlLeagues.InsertItem("Ligue Nationale", 2, 3, hRoot);
	ctlLeagues.InsertItem(_T("2004-2005"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2003-2004"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2002-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2000-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("1999-2000"), 4, 5, hSeason);

	hSeason = ctlLeagues.InsertItem("Major League Soccer", 2, 3, hRoot);
	ctlLeagues.InsertItem(_T("2004-2005"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2003-2004"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2002-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2000-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("1999-2000"), 4, 5, hSeason);

	hSeason = ctlLeagues.InsertItem("Primera Liga", 2, 3, hRoot);
	ctlLeagues.InsertItem(_T("2004-2005"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2003-2004"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2002-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("2000-2001"), 4, 5, hSeason);
	ctlLeagues.InsertItem(_T("1999-2000"), 4, 5, hSeason);

	ctlLeagues.Expand(hRoot, TVE_EXPAND);
}
  27. In the Class View, under the CExerciseDoc node, double-click OnNewDocument
  28. To display the tree when the application comes up, call the above method the pointer to the left view class:
      
    BOOL CExerciseDoc::OnNewDocument()
{
	if (!CDocument::OnNewDocument())
		return FALSE;

	this->pLeftView->CreateLeagues();

	return TRUE;
}
  29. In the top section of the file, add a #include "LeftView.h" line:
      
    // ExerciseDoc.cpp : implementation of the CExerciseDoc class
//

#include "stdafx.h"
#include "Championships.h"

#include "ExerciseDoc.h"
#include "LeftView.h"
  30. To add the options to the tree list, access the OnInitialUpdate() event and type the following line that sets the style:
      
    void CLeftView::OnInitialUpdate()
{
	GetTreeCtrl().ModifyStyle(NULL, TVS_HASBUTTONS | TVS_HASLINES | TVS_LINESATROOT);

	CTreeView::OnInitialUpdate();
}
  31. To give more room to the list tree, access the OnCreateClient and change the width of the left frame as follows:
      
    BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/,
	CCreateContext* pContext)
{
	// create splitter window
	if (!m_wndSplitter.CreateStatic(this, 1, 2))
		return FALSE;

	if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CLeftView), CSize(200, 100), pContext) ||
		!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CRightView), CSize(100, 100), pContext))
	{
		m_wndSplitter.DestroyWindow();
		return FALSE;
	}

	return TRUE;
}

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
	if( !CFrameWnd::PreCreateWindow(cs) )
		return FALSE;

	cs.style &= ~FWS_ADDTOTITLE;

	return TRUE;
}
  32. Test the application
     
  33. After using it, close it and return to your programming environment
  34. When an item is selected in the tree, whether by the user or else, you can specify what should happen in another view, such as the right frame for our example. To make this exercise simpler and clearer, we will call a different function of the right frame when a category of node is selected in the left frame (of course, there are other ways to do this but for now, we will use this simplistic approach).
    First of all, we need a mechanism to erase the list view every time it must be updated, otherwise, the items to display would just be added to the existing ones.
    In the Class View, right-click the CRightView class -> Add Member Function...
  35. Set the return type to void and the function name to ResetLeagues. Keep it public and press Enter
  36. Implement the method as follows:
      
    void CRightView::ResetLeagues()
{
	CListCtrl &ctlLView = GetListCtrl();

	ctlLView.DeleteAllItems();
	while(ctlLView.DeleteColumn(0))
		;

	UpdateWindow();
}
  37. When the root node is selected in the left frame, we will display a list of leagues.
    In the Class View, right-click the CRightView class -> Add Member Function...
  38. Set the return type to void and the function name to DisplayLeagues. Keep it public and press Enter
  39. Implement the method as follows:
      
    void CRightView::DisplayLeagues()
{
	CListCtrl &ctlLeagues = this->GetListCtrl();

	ResetLeagues();

	ctlLeagues.InsertColumn(0, _T("Country"), LVCFMT_LEFT, 80);
	ctlLeagues.InsertColumn(1, _T("League Name"), LVCFMT_LEFT, 160);
	ctlLeagues.InsertColumn(2, _T("Address"), LVCFMT_LEFT, 180);
	ctlLeagues.InsertColumn(3, _T("Web Site"), LVCFMT_LEFT, 200);

	int nItem;

	nItem = ctlLeagues.InsertItem(0, "England");
	ctlLeagues.SetItemText(nItem, 1, "English Premier League");
	ctlLeagues.SetItemText(nItem, 2, "Don't Know");
	ctlLeagues.SetItemText(nItem, 3, "http://www.premierleague.com");
	
	nItem = ctlLeagues.InsertItem(0, "Italie");
	ctlLeagues.SetItemText(nItem, 1, "Lega Nazionale Professionisti");
	ctlLeagues.SetItemText(nItem, 2, "Forgot");
	ctlLeagues.SetItemText(nItem, 3, "http://www.lega-calcio.it");

	nItem = ctlLeagues.InsertItem(0, "Kamerun");
	ctlLeagues.SetItemText(nItem, 1, "Ligue Nationale");
	ctlLeagues.SetItemText(nItem, 2, "Can't Remember");
	ctlLeagues.SetItemText(nItem, 3, "http://www.cameroon.fifa.com");

	nItem = ctlLeagues.InsertItem(0, "U.S.A.");
	ctlLeagues.SetItemText(nItem, 1, "Major League Soccer");
	ctlLeagues.SetItemText(nItem, 2, "Can't Remember");
	ctlLeagues.SetItemText(nItem, 3, "http://www.mlsnet.com");

	nItem = ctlLeagues.InsertItem(0, "Espagne");
	ctlLeagues.SetItemText(nItem, 1, "Primera Liga");
	ctlLeagues.SetItemText(nItem, 2, "Where?");
	ctlLeagues.SetItemText(nItem, 3, "Need to find out");
}
  40. In the same way, when an item is selected in the list, we will find out what its string is, pass that string to the list view and then update the list view accordingly.
    In the Class View, right-click the CRightView class -> Add Member Function...
  41. Set the return type to void and the function name to DisplayLeague(CString League). Keep it public and press Enter
  42. Implement the method as follows:
      
    void CRightView::DisplayLeague(CString League)
{
	CListCtrl &ctlRightView = this->GetListCtrl();

	ResetLeagues();

	ctlRightView.InsertColumn(0,  _T("Season"), LVCFMT_LEFT,   80);
	ctlRightView.InsertColumn(1,  _T("Rank"),   LVCFMT_LEFT,   50);
	ctlRightView.InsertColumn(2,  _T("Team"),   LVCFMT_LEFT,  100);
	ctlRightView.InsertColumn(3,  _T("P"),      LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(4,  _T("W"),      LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(5,  _T("D"),      LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(6,  _T("L"),      LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(7,  _T("F"),      LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(8,  _T("A"),      LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(9,  _T("GD"),     LVCFMT_RIGHT,  30);
	ctlRightView.InsertColumn(10, _T("Pts"),    LVCFMT_RIGHT,  30);

	int nItem;

	if( League == "English Premier League" )

  46. To make this exercise again simpler, we will mostly care only for the Report View
    Access the OnInitialUpdate() event of the CRightView class and change it as follows:
      
    void CRightView::OnInitialUpdate()
{
	CListView::OnInitialUpdate();

	CListCtrl &ctlCarParts = this->GetListCtrl();
	ctlCarParts.ModifyStyle(NULL, LVS_REPORT);
	ctlCarParts.SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES);
}
  47. Now that we have the necessary functions we can react when a node changes in the tree view.
    Using either the ClassWizard, the Messages section of the Properties, or whatever, generate a TVN_SELCHANGED message for the CLeftView class
     
  48. Implement the OnSelchanged event as follows:
      
    // LeftView.cpp : implementation of the CLeftView class
//

#include "stdafx.h"
#include "Championships.h"

#include "ExerciseDoc.h"
#include "LeftView.h"
