Easy way to access listview from treeview and vice versa

Introduction

This is an easy way to access the listview from treeview and vice-versa in a Windows Explorer Style MFC application. (It is specified in step number 5 of 6 in the MFC app wizard)

Let's say the project name is "F".

What is to be done ?

• Create an SDI application with Windows Explorer style, with name "F".
• Add a public member variable (a pointer to CTreeView type) to CLeftView class with name m_treeview. This will be of the shape CTreeView * m_treeview.
• Add a public member variable (a pointer to CListView type) to CFView class (where F is the name of the app.) with name m_listview. This will be of the shape CListView * m_listview.
• Add a public member function and which is void with name GetViews() to the CMainFrame class
• Write the following code in the function:
  MC++

  void CMainFrame::GetViews()
  {
  //Code beginning
   //get the right view (the list view)
   CWnd* pWnd = m_wndSplitter.GetPane(0, 1);
   //cast the right view to the CFView type where F is 
   //the name of Application and store it in list variable
   CFView* list= DYNAMIC_DOWNCAST(CFView, pWnd);
   //get the left view (the tree view)
   pWnd = m_wndSplitter.GetPane(0, 0);
   //cast it to CLeftView type and store it in tree variable
   CLeftView * tree = DYNAMIC_DOWNCAST(CLeftView, pWnd);
   //store the list view in the m_listview variable 
   //(member of CLeftView class)
   tree->m_listview=list;
   //store the tree view in the m_treeview 
   //variable (member of CFView class)
   list->m_treeview=tree;
   //end of code
  }

• Add GetViews(); in the CMainFrame::OnCreate() function just before "return true;"

So how do I use that code

To access the ListView from Treeview,

• On any event you want (click, double click, select) in the CLeftView class, add the following code:
  MC++

  m_listview->GetListCtrl().InsertColumn(0,"Test");

To access the TreeView From ListView,

• On any event you want (click ,double click, select) in the CFView class, add the following code:
  MC++

  m_treeview->GetTreeCtrl().InsertItem("Test");

I hope that I helped.
