lptvdi
Address of an NMTVDISPINFO structure. The itemOld and itemNew members contain valid information about the currently selected item and the newly selected item. The action member indicates whether a mouse or keyboard action is causing the selection to change. For a list of possible values, see the description of the TVN_SELCHANGED notification message.

If the pszText member of the item's TVITEM structure is the LPSTR_TEXTCALLBACK value, the control sends this notification to set the item's text. In this case, the mask member of lptvdi will have the TVIF_TEXT flag set.
