/* Treeview control
*
* Copyright 1998 Eric Kohl <ekohl@abo.rhein-zeitung.de>
* Copyright 1998,1999 Alex Priem <alexp@sci.kun.nl>
*
*
* TODO:
* list-handling stuff: sort, sorted insertitem.
* [should be merged with mm-handling stuff as done in listview]
* refreshtreeview:
-small array containing info about positions.
-better implementation of RefreshItem:
1) draw lines between parents
2) draw items
3) draw lines from parent<->items.
-implement partial drawing?
* -drag&drop: TVM_CREATEDRAGIMAGE should create drag bitmap.
* -scrollbars: horizontal scrollbar doesn't work.
* -Unicode messages
* -check custom draw
* -I_CHILDRENCALLBACK
* FIXME: check fontsize. (uRealItemHeight)
* test focusItem (redraw in different color)
uHotItem
Edit: needs timer
better implementation.
* WM_HSCROLL is broken.
* use separate routine to get item text/image.
*
* Separate drawing/calculation.
*
* FIXMEs (for personal use)
Expand: -ctlmacro expands twice ->toggle.
-DblClick: ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
-treehelper: stack corruption makes big window.
