11 * TODO:
12 * Using DPA to store the item ptr would be good.
13 * Node label edition is implemented but something appened in wine in the
14 * two last weeks of march 99 that broke it.
15 * refreshtreeview:
16 -small array containing info about positions.
17 -better implementation of RefreshItem:
18 1) draw lines between parents
19 2) draw items
20 3) draw lines from parent<->items.
21 -implement partial drawing?
22 * -drag&drop: TVM_CREATEDRAGIMAGE should create drag bitmap.
23 * -scrollbars: horizontal scrollbar doesn't work.
24 * -Unicode messages
25 * -check custom draw
26 * -I_CHILDRENCALLBACK
27 * FIXME: check fontsize. (uRealItemHeight)
28 * test focusItem (redraw in different color)
29 uHotItem
30 Edit: needs timer
31 better implementation.
32 * WM_HSCROLL is broken.
33 * use separate routine to get item text/image.
34 *
35 * Separate drawing/calculation.
36 *
37 * FIXMEs (for personal use)
38 Expand: -ctlmacro expands twice ->toggle.
39 -DblClick: ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
40 -treehelper: stack corruption makes big window.
