Overview

I needed a FileTree control to use in an ATL/WTL project and I decided to port MFC Control to WTL. The following ATL files contain the port:

• FileFind.h/FileFind.cpp - Contain the CFileFind class and implementation for WTL which performs local file searches
• WtlFileTreeCtrl.h/WtlFileTreeCtrl.cpp - Contain the CWtlFileTreeCtrl class and implementation for WTL

How to use the control in your WTL App:

1. Create a WTL Project
2. Design the dialog and add the Tree control
3. Add the WtlFileTreeCtrl.h header file to your project
4. Assign a CWtlFileTreeCtrl to your tree.
5. In OnInitDialog(), subclass tree control (CWtlFileTreeCtrl) to ID using the SubclassWindow method.
6. In your dialog, don't forget to add the macro REFLECT_NOTIFICATIONS which allows the CWtlFileTreeCtrl to get messages like TVN_ITEMEXPANDING.

#include "WtlFileTreeCtrl.h"


//...


class CMainDlg : public CDialogImpl<CMainDlg>
{
     BEGIN_MSG_MAP(CMainDlg)
          ...
          MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)
          REFLECT_NOTIFICATIONS()
     END_MSG_MAP()
     ...
     LRESULT OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, 
         LPARAM /*lParam*/, BOOL& /*bHandled*/);
     ...
     CWtlFileTreeCtrl m_Tree;
     ...
};

//...


LRESULT CMainDlg::OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, 
        LPARAM /*lParam*/, BOOL& /*bHandled*/) 

{
     ...
     m_Tree.SubclassWindow( ::GetDlgItem( m_hWnd, IDC_TREE1 ) );
     ...
}

Requirements

You will require the WTL Libraries, these can be downloaded from the microsoft site.

Note - This control uses the STL std::string class and the STL std::vector template class.
