haiku/headers/os/interface/MenuItem.h
Axel Dörfler 083de48a4b * Rewrote the trigger selection mechanism: it now searches for uppercase
characters first, and then falls back to take everything. fTrigger is now
  uint32 and works with all unicode characters; unlike in BeOS, the
  MenuTriggerTest application now works correctly in Haiku.
* fTriggerIndex is now a character position, not a byte position of the label;
  this allows BMenuItem::DrawContent() to draw the trigger at the correct
  position, even if there are multi-byte UTF-8 characters.
* The above fixed bug #1506; triggers are still not working, though.
* Rewrote Menu.h header.
* Renamed all private methods (that are not called by BWindow) to have the
  underscore prefix.
* Removed unused methods.
* Some minor cleanup.
