/*!
\qmlmethod bool InputMethod::keyEvent(int key, string text, int modifiers)
The purpose of this method is to handle the key events generated by the the
input engine.
The \a key parameter specifies the code of the key to handle. The key code
does not distinguish between capital and non-capital letters. The \a
text parameter contains the Unicode text for the key. The \a modifiers
parameter contains the key modifiers that apply to \a key.
This method returns \c true if the key event was successfully handled.
If the return value is \c false, the key event is redirected to the default
input method for futher processing.
*/
/*!
\qmlmethod InputMethod::reset()
This method is called by the input engine when this input method needs to be
reset. The input method must reset its internal state only. The main
difference to the update() method is that reset() modifies only
the input method state; it must not modify the input context.
*/
/*!
\qmlmethod InputMethod::update()
This method is called by the input engine when the input method needs to be
updated. The input method must close the current pre-edit text and
restore the internal state to the default.
*/
/*!
\qmlmethod list<int> InputMethod::selectionLists()
Returns the list of selection types used for this input method.
This method is called by the input engine when the input method is being
activated. The input method can reserve the selection lists for its use
by returning a list of selection list types required.
*/
/*!
\qmlmethod int InputMethod::selectionListItemCount(int type)
Returns the number of items in the selection list identified by \a type.
*/
/*!
\qmlmethod var InputMethod::selectionListData(int type, int index, int role)
Returns item data for a selection list identified by \a type. The \a role
parameter specifies which data is requested. The \a index parameter is a
zero based index into the selecteion list.
*/
/*!
\qmlmethod void InputMethod::selectionListItemSelected(int type, int index)
This method is called when an item at \a index has been selected by the
user. The selection list is identified by the \a type parameter.

changed.
