[Qt-qml] [Qt-components] QML TextInput, extending Qt input method query and input method event

[henrik.hartz at nokia.com]

Hi Kimmo,

I suppose the only way to do this the 'proper' way is to add the appropriate hooks from C++ - meaning you need a new QML element. A new QML element could be added as a plugin, which would prevent LMT dependancies in  QML. Perhaps someone on the qt-qml list could comment on how to best approach this? (the crosspost didn't go through, perhaps you're not subscribed?)
