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.

4430 * TREEVIEW_ProcessLetterKeys
4431 *
4432 * Processes keyboard messages generated by pressing the letter keys
4433 * on the keyboard.
4434 * What this does is perform a case insensitive search from the
4435 * current position with the following quirks:
4436 * - If two chars or more are pressed in quick succession we search
4437 * for the corresponding string (e.g. 'abc').
4438 * - If there is a delay we wipe away the current search string and
4439 * restart with just that char.
4440 * - If the user keeps pressing the same character, whether slowly or
4441 * fast, so that the search string is entirely composed of this
4442 * character ('aaaaa' for instance), then we search for first item
4443 * that starting with that character.
4444 * - If the user types the above character in quick succession, then
4445 * we must also search for the corresponding string ('aaaaa'), and
4446 * go to that string if there is a match.
4447 *
4448 * RETURNS
4449 *
4450 * Zero.
4451 *
4452 * BUGS
4453 *
4454 * - The current implementation has a list of characters it will
4455 * accept and it ignores everything else. In particular it will
4456 * ignore accentuated characters which seems to match what
4457 * Windows does. But I'm not sure it makes sense to follow
4458 * Windows there.
4459 * - We don't sound a beep when the search fails.
4460 * - The search should start from the focused item, not from the selected
4461 * item. One reason for this is to allow for multiple selections in trees.
4462 * But currently infoPtr->focusedItem does not seem very usable.
