Iterating Over All Tree Items in wxTreeCtrl

[Everydaydiesel]

Hello, I have the following recursive code but the problem is that it does not iterate over the last tree view item. I am unsure why really.

Code: Select all

void Form::GetAllTreeViewItems(wxTreeCtrl *tv, const wxTreeItemId& tiiCurrent)
{
    wxTreeItemIdValue cookie;
    wxTreeItemId child = tv->GetFirstChild(tiiCurrent, cookie);

    while (child.IsOk())
    {
        m_tiiAllTreeViewItems.push_back(child);
        string sCurrentPath = GetPathOfTreeViewItem(child);
        wxMessageBox(sCurrentPath);

        GetAllTreeViewItems(tv, child);
        child = tv->GetNextChild(child, cookie);
    }

Hi,
So it prints all of them in the message box but the last one?

Thank you.

The loop just doesn't work this way. The first parameter to GetFirstChild/GetNextChild must remain the same, but with "child = tv->GetNextChild(child, cookie);" you immediately change it.

Check the method "GetItemsRecursively" from the "treectrl" sample which shows how it works.
