1、
I read some source code, I think that original ideas is that get last word and compare it with libPathSep.
but the paramter of wxString::SubString is begin position with end position, not begin position with length.
libPath.SubString(libPath.Length() - 1, 1) ;//will Over the border

So I replace SubString to Mid, it run fine.

define :

Code
wxString wxString::SubString(size_t from, size_t to) const


 and
Code
wxString wxString::Mid(size_t first, size_t count = wxSTRING_MAXLEN) const






2、 About wxTreeItemId problem(wxTreeItemId  don't always==true)

    If you run codeblocks and open project 、 select "Build Option" Menu , then sel.IsOk==false
    Sometime I will get crash in this problem.
   


Code
FileTreeData* ftd = (FileTreeData*)tree->GetItemData(sel);

to

Code
FileTreeData* ftd=sel.IsOk()?(FileTreeData*)tree->GetItemData(sel):0;
