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_EXPANDPARTIAL, TVIS_EX_FLAT,
37 * TVIS_EX_DISABLED
38 *
39 * Make the insertion mark look right.
40 * Scroll (instead of repaint) as much as possible.

4474 * TREEVIEW_ProcessLetterKeys
4475 *
4476 * Processes keyboard messages generated by pressing the letter keys
4477 * on the keyboard.
4478 * What this does is perform a case insensitive search from the
4479 * current position with the following quirks:
4480 * - If two chars or more are pressed in quick succession we search
4481 * for the corresponding string (e.g. 'abc').
4482 * - If there is a delay we wipe away the current search string and
4483 * restart with just that char.
4484 * - If the user keeps pressing the same character, whether slowly or
4485 * fast, so that the search string is entirely composed of this
4486 * character ('aaaaa' for instance), then we search for first item
4487 * that starting with that character.
4488 * - If the user types the above character in quick succession, then
4489 * we must also search for the corresponding string ('aaaaa'), and
4490 * go to that string if there is a match.
4491 *
4492 * RETURNS
4493 *
4494 * Zero.
4495 *
4496 * BUGS
4497 *
4498 * - The current implementation has a list of characters it will
4499 * accept and it ignores everything else. In particular it will
4500 * ignore accentuated characters which seems to match what
4501 * Windows does. But I'm not sure it makes sense to follow
4502 * Windows there.
4503 * - We don't sound a beep when the search fails.
4504 * - The search should start from the focused item, not from the selected
4505 * item. One reason for this is to allow for multiple selections in trees.
4506 * But currently infoPtr->focusedItem does not seem very usable.
