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