[Qt-interest] Meaning of Qt::Key_<>, etc for non-latin keyboards ?

[Constantin Makshin]

When a non-latin keyboard layout is used, QKeyEvent::key() returns code of the upper-case version of the character, i.e. QChar(keyEvent->key()) is the upper-case character the user has pressed. For example, if I press 'Ф' (Cyrillic letter usually placed on the same key as latin 'A'), QKeyEvent::key() returns 1060 (0x424) — code of the 'Ф' letter in Unicode character set.

At least it works this way on my Debian system. :)
I guess on other systems this function has the same behavior, at least because there are too many layouts to make it possible to implement simple and platform-independent "non-latin <--> latin" key code conversion/mapping.
