<![CDATA[How to get nativeVirtualKey for arrow keys [SOLVED]]]>Hi.
I need to find a method how to get nativeVirtualKey for arrow keys.
I've tried so: QKeyEvent(QEvent::KeyPress, Qt::Key_Up, Qt::NoModifier).nativeVirtualKey()
but it's not work.

oh, i thought Qt would send same Qt::Key_xx
regardless of the actual keyboard.

Good to know it wont.

So I wanted to use nativeVirtualKey to perform the same reaction on same keys (but in different language). But it hadn't worked for arrow keys: Qt::Key_Up has value 16 777 235. So I needed to do something with that.

Hi
yes sym = symbol key. bad name. its more like native key value.
The reason its not working is that the native/os/nativeVirtualKey is part of the real os event and added to the
QKeyEvent class when a real OS event happens.
So I do not think creating one will contain the info you want.

I have never seen such function but Qt is big so there might be something.
You might be able to borrow some from KDE
http://api.kde.org/4.x-api/kdelibs-apidocs/kdeui/html/kkeyserver__win_8cpp_source.html

Can I ask why you want native values and cant just use Qt::Key_xx ?

I'm sorry. I meant this in last message: QKeyEvent(QEvent::KeyPress, Qt::Key_Up, Qt::NoModifier).nativeScanCode(); It had not worked too, and now I almost understand why. Explain please, what is sym key? Symbol key?
I don't know am I right, but I think that it hadn't worked because real event calls this constructor with ready nativeVirtualKey and scanCode:
QKeyEvent::QKeyEvent(Type type, int key, Qt::KeyboardModifiers modifiers, quint32 nativeScanCode, quint32 nativeVirtualKey, quint32 nativeModifiers, const QString & text = QString(), bool autorep = false, ushort count = 1)
I thought, this codes are calculating somewhere In constructor, but as i see - they need to be listed when constructor is called.

I get good nativeVirtualKey in keyboardEvent and it also equals 37, 38, 39, 40, but I wanted to get constants anywhere else and not to use Windows constants. Is there any possible way?

No its another function than native virtualkey.

void keyPressEvent ( QKeyEvent* ke )
    {
        int nativeCode = ke->nativeScanCode();
        qDebug() << nativeCode;

   }

lists values for arrow keys. Not sure sure if it is the one you want.

For test I also tried nativeVirtualKey and it returns
37,38,39,40 for arrows which seems to be VK_LEFT etc.

From this line I assume you try to use it as lookup call ?QKeyEvent(QEvent::KeyPress, Qt::Key_Up, Qt::NoModifier).nativeVirtualKey();

You are not catching a real key even but try into to convert from qt::key_up to sort of like VK_ARROWUP ?

I do not think this can work since the real event provides the sym key and here you just construct a fake one so this info is not there.

QKeyEvent(QEvent::KeyPress, Qt::Key_Up, Qt::NoModifier).nativeVirtualKey();
This is not works too - this statement returns 0.

hi and welcome

Did you test with quint32 QKeyEvent::nativeScanCode() const ?
