How to hide and disable virtual keyboad key?

[Nekk]

Hi all,
I'd like to modify the "style.qml" file to hide some keys of the virtual keyboard. In particular, I want to hide the follow keys:

• language (item "languageKeyPanel")
• handwriting (item "handwritingKeyPanel")
• mode (item "modeKeyPanel")
• hide (item "hideKeyPanel")

I can hide the key by setting its "visible" property to "false" but I can't disable the function associated to its touch event.

Any advice?

Another question. How can I rearrange the keyboard layout?

Many thanks
