21 * Note that TREEVIEW_INFO * and HTREEITEM are the same thing.
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.
29 * missing notifications: NM_SETCURSOR, TVN_GETINFOTIP, TVN_KEYDOWN,
30 * TVN_SETDISPINFO, TVN_SINGLEEXPAND
32 * missing styles: TVS_FULLROWSELECT, TVS_INFOTIP, TVS_NOSCROLL,
33 * TVS_RTLREADING, TVS_TRACKSELECT
35 * missing item styles: TVIS_CUT, TVIS_EXPANDPARTIAL
37 * Make the insertion mark look right.
38 * Scroll (instead of repaint) as much as possible.

4226 * TREEVIEW_ProcessLetterKeys
4228 * Processes keyboard messages generated by pressing the letter keys
4230 * What this does is perform a case insensitive search from the
4231 * current position with the following quirks:
4232 * - If two chars or more are pressed in quick succession we search
4233 * for the corresponding string (e.g. 'abc').
4234 * - If there is a delay we wipe away the current search string and
4235 * restart with just that char.
4236 * - If the user keeps pressing the same character, whether slowly or
4237 * fast, so that the search string is entirely composed of this
4238 * character ('aaaaa' for instance), then we search for first item
4239 * that starting with that character.
4240 * - If the user types the above character in quick succession, then
4241 * we must also search for the corresponding string ('aaaaa'), and
4242 * go to that string if there is a match.
4250 * - The current implementation has a list of characters it will
4251 * accept and it ignores averything else. In particular it will
4252 * ignore accentuated characters which seems to match what
4253 * Windows does. But I'm not sure it makes sense to follow
4255 * - We don't sound a beep when the search fails.
4256 * - The search should start from the focused item, not from the selected
4257 * item. One reason for this is to allow for multiple selections in trees.
4258 * But currently infoPtr->focusedItem does not seem very usable.
