21 * Note that TREEVIEW_INFO * and HTREEITEM are the same thing.
22 *
23 * Note2: All items always! have valid (allocated) pszText field.
24 * If item's text == LPSTR_TEXTCALLBACKA we allocate buffer
25 * of size TEXT_CALLBACK_SIZE in DoSetItem.
26 * We use callbackMask to keep track of fields to be updated.
27 *
28 * TODO:
29 * missing notifications: NM_SETCURSOR, TVN_GETINFOTIP, TVN_KEYDOWN,
30 * TVN_SETDISPINFO, TVN_SINGLEEXPAND
31 *
32 * missing styles: TVS_FULLROWSELECT, TVS_INFOTIP, TVS_NOSCROLL,
33 * TVS_RTLREADING, TVS_TRACKSELECT
34 *
35 * missing item styles: TVIS_CUT, TVIS_EXPANDPARTIAL
36 *
37 * Make the insertion mark look right.
38 * Scroll (instead of repaint) as much as possible.

4196 * TREEVIEW_ProcessLetterKeys
4197 *
4198 * Processes keyboard messages generated by pressing the letter keys
4199 * on the keyboard.
4200 * What this does is perform a case insensitive search from the
4201 * current position with the following quirks:
4202 * - If two chars or more are pressed in quick succession we search
4203 * for the corresponding string (e.g. 'abc').
4204 * - If there is a delay we wipe away the current search string and
4205 * restart with just that char.
4206 * - If the user keeps pressing the same character, whether slowly or
4207 * fast, so that the search string is entirely composed of this
4208 * character ('aaaaa' for instance), then we search for first item
4209 * that starting with that character.
4210 * - If the user types the above character in quick succession, then
4211 * we must also search for the corresponding string ('aaaaa'), and
4212 * go to that string if there is a match.
4213 *
4214 * RETURNS
4215 *
4216 * Zero.
4217 *
4218 * BUGS
4219 *
4220 * - The current implementation has a list of characters it will
4221 * accept and it ignores averything else. In particular it will
4222 * ignore accentuated characters which seems to match what
4223 * Windows does. But I'm not sure it makes sense to follow
4224 * Windows there.
4225 * - We don't sound a beep when the search fails.
4226 * - The search should start from the focused item, not from the selected
4227 * item. One reason for this is to allow for multiple selections in trees.
4228 * But currently infoPtr->focusedItem does not seem very usable.
