Save key input with japanish language (use of QInputMethodEvent)



  • Hi,

    I have a Qt application and need to save user key input in an array. I mean, what user writes using keyboard (without using any textedit or similar) must be saved in an array.

    If I Use @MyClass::eventFilter( QObject *obj, QEvent *event )@

    method, 'QEvent::KeyPress' gives me input chars (keyEvent->key()), BUT NOT non-Latin characters, i.e. when japanish language is set.

    I have read about QInputMethodEvent Class (http://qt-project.org/doc/qt-5.0/qtgui/qinputmethodevent.html#details), and it seems to be what I need ('...Input methods are widely used to enter text for languages with non-Latin alphabets.'), BUT I do not understand how to use it...

    I have tested input panel example (http://qt-project.org/doc/qt-4.8/tools-inputpanel.html), and altough I understand what it does, I do not know how to use this classes for muy purpose.

    As far as I know:

    I need a Widget (class A) which receives input chars using @void inputMethodEvent( QInputMethodEvent* m )@

    previous setAttribute( Qt::WA_InputMethodEnabled). But this method is called from a QInputContext. When a QTextEdit is used, a generic QInputContext calls automatically this method and the text is displayed on the edit.
    But in my case I have no textEdit, so I suppose I need a class B which inherits QInputContext and sends this event somewhen. But I do not how to do this... If I use '::eventFilter' in class B, I receive char input, BUT when I set japanish, as I said previously.

    I am really stuck, so I would appreciate any help.

    Thanks in advance,

    Diego
