CMarkupTreeCtrl problem

 

In general, I think the native Windows tree control is a disaster :(

 

Replacing your "NULL" with the actual text of the item does the trick. Windows seems to calculate the widths upon the InsertItem call!

 

---------------------------------------------------------------------------

CString GetInnerText(CXTPMarkupObject* pParent);

 

HTREEITEM CMarkupTreeCtrl::AddItem(LPCTSTR lpszItem, int nImage, int nSelectedImage, HTREEITEM hParent/* = TVI_ROOT*/, HTREEITEM hInsertAfter/* = TVI_LAST*/)
{
    CXTPMarkupUIElement* pUIElement = Parse(lpszItem);
   
    HTREEITEM hItem;

    if (pUIElement)
    {
        hItem = InsertItem(GetInnerText(pUIElement), nImage, nSelectedImage, hParent, hInsertAfter);
        SetItemData(hItem, (DWORD_PTR)pUIElement);
    }
    else
    {
        hItem = InsertItem(lpszItem, nImage, nSelectedImage, hParent, hInsertAfter);
    }

    return hItem;
}
