QString convert unicode

[Jeronimo]

@kshegunov said in QString convert unicode:

wchar_t buffer[5]

say me the follow:
'inicializando' : no se puede realizar la conversi¢n de 'QByteArray' a 'char *'
No hay disponible ning£n operador de conversi¢n definido por el usuario que pueda realizar esta conversi¢n, o bien no se puede llamar al operador

In other words when i do this

wchar_t buffer[5];
QString string = QString::fromWCharArray(buffer);
char *utf8encoded = string.toUtf8();

I can't do the conversion.

You really should check the docs on this.
I've made a minor mistake, but it's easily correctable.

QByteArray utf8data = string.toUtf8();
const char * utf8encoded = utf8data.constData();

@kshegunov said in QString convert unicode:

QByteArray utf8data = string.toUtf8();
const char * utf8encoded = utf8data.constData();

one question normally i think must show unicode text like this :

Normally i can do this
QString::fromUtf16((ushort*)buffer)

But i have one problem with this only show me in unicode when i am using some modificator like ctrl. It's for one keyboard in different languages.

[kshegunov]

I don't understand the question. Unicode has little to do with control or with the keyboard, it's an encoding for text, not a device driver ...

@kshegunov i think is problem of my instance or i'm doing something wrong.

Hi,

Then tell us what you are trying to do.

[Jeronimo]

@SGaist Sorry i said instance¿? i wanted to say encoding*

[SGaist]

That still doesn't explain what you are trying to do.

Why do you need all these conversion ?

[Jeronimo]

@SGaist i'm trying to do keyboard in different languages and like i was trying to show key's in other languages like(german or others..) i couldn't because i can't get unicode text to translate it.

[SGaist]

Something like the QtVirtualKeyboard module ?

[Jeronimo]

@SGaist Nope it's for windows so i am using setwindowshookex

[SGaist]

Why not make use of Window's virtual keyboard ?
