24 * Note that TREEVIEW_INFO * and HTREEITEM are the same thing.
25 *
26 * Note2: If item's text == LPSTR_TEXTCALLBACKA we allocate buffer
27 * of size TEXT_CALLBACK_SIZE in DoSetItem.
28 * We use callbackMask to keep track of fields to be updated.
29 *
30 * TODO:
31 * missing notifications: TVN_GETINFOTIP, TVN_KEYDOWN,
32 * TVN_SETDISPINFO, TVN_SINGLEEXPAND
33 *
34 * missing styles: TVS_FULLROWSELECT, TVS_INFOTIP, TVS_RTLREADING,
35 *
36 * missing item styles: TVIS_CUT, TVIS_EXPANDPARTIAL
37 *
38 * Make the insertion mark look right.
39 * Scroll (instead of repaint) as much as possible.
