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

4333 * TREEVIEW_ProcessLetterKeys
4334 *
4335 * Processes keyboard messages generated by pressing the letter keys
4336 * on the keyboard.
4337 * What this does is perform a case insensitive search from the
4338 * current position with the following quirks:
4339 * - If two chars or more are pressed in quick succession we search
4340 * for the corresponding string (e.g. 'abc').
4341 * - If there is a delay we wipe away the current search string and
4342 * restart with just that char.
4343 * - If the user keeps pressing the same character, whether slowly or
4344 * fast, so that the search string is entirely composed of this
4345 * character ('aaaaa' for instance), then we search for first item
4346 * that starting with that character.
4347 * - If the user types the above character in quick succession, then
4348 * we must also search for the corresponding string ('aaaaa'), and
4349 * go to that string if there is a match.
4350 *
4351 * RETURNS
4352 *
4353 * Zero.
4354 *
4355 * BUGS
4356 *
4357 * - The current implementation has a list of characters it will
4358 * accept and it ignores averything else. In particular it will
4359 * ignore accentuated characters which seems to match what
4360 * Windows does. But I'm not sure it makes sense to follow
4361 * Windows there.
4362 * - We don't sound a beep when the search fails.
4363 * - The search should start from the focused item, not from the selected
4364 * item. One reason for this is to allow for multiple selections in trees.
4365 * But currently infoPtr->focusedItem does not seem very usable.
