[HELP] Recursive sync wxDir and wxTreeCtrl

[mykula91]

Hello,

I am new in wxWidgets. I need to write application, such as file browser. It is neede to expand and collapses all subdirectories.
I have a problem with recursion in enumerating the tree.

Code: Select all

 
 wxDir dir3, dir2;
    wxString myParentFolder = _T("C:/Qt");
    wxString filename;
    bool cont, can;
    wxString temp;


bool newTreeFrame::UdateTree(wxString myParentFolder, wxTreeItemId root,  bool cont)
    {
        dir3.Open( myParentFolder );
        cont = dir3.GetFirst(&filename);

        if (cont)
        {
            Child = my_treectrl->AppendItem(root,filename, 0);
            UdateTree((myParentFolder+"/"+filename), Child, cont);
        }
        else
        {
            return false;
        }

    }

What exactly is the problem?

And did you look into wxGenericDirCtrl ? It sounds like it does what you need.
http://docs.wxwidgets.org/trunk/classwx ... _ctrl.html

Build the "widgets" sample that comes with wxWidgets to see the control in action.

wxGenericDirCtrl resolved my problem. Thanks very much for your help.

I have a second question - is it possible to save the state of wxGenericDirCtrl object between sessions?

You mean which folders are expanded and which not? There is no function for this in wxGenericDirCtrl itself, you'd have to implement that yourself.

Is wxPersistentManager would be a good idea? I have no experience with using this tool.

Hi,
I think wxPersistentyManager is for storing and retrieving the control position/size.
I may be wrong though. Try it.

Thank you.

OneEyeMan is correct. Use wxConfig or similar for storing whatever you want and store it before program exits and restore immediately after UI creation is done!
