  Digia has been doing a lot of work in Qt here.
  Their "Flow'd":http://www.flowd.com application, their Qt4.5 "Web Browser":http://www.digia.com/browser and plenty of other stuff on their website.
  I wonder if they have used this QML keyboard in anything. They certainly didn't use it in Flowd.

Where is there an example on how to use the CLKeyboard ?

I would like to use it "linked to" a TextInput item. How do I create "the link" ?

Thanks for your answer.

rodrigob, I've made a simple virtual keyboard for touchscreen displays.
There are also some example to use it with Qt.

How do you delete letters with this keyboard ?

[rotoZOOM]

There is exists Backspace key on the top/right corner.

[aabc]

And you just do text += <the backspace code> ?

[rotoZOOM]

No. This is just UI. It sends signal which of key is pressed.
In case of backspace pressed it sends sigButtonPressed ('backspace').
Your application should handle it.
You can see it from my example.

[aabc]

Can I use it with QML TextInput ?

[rotoZOOM]

Yes. You can manual handle sigButtonPressed and in case of button=='backspace' remove character just before cursorPosition of the TextInput.

[aabc]

Isnt there is something more generic that use sendEvent(QKeyEvent) that simulate the real Keyboard ?

[rotoZOOM]

In my example I do
QCoreApplication::postEvent(_target, key_event_press);
QCoreApplication::postEvent(_target, key_event_release);

that, I believe, emulate click on to the key.

[aabc]

What is the _target ? Is it the TextInput ?

[rotoZOOM]

It is QWidget object, that setted by client and accept QKeyEvent

[aabc]

Did you try it with a QML Item ?

[rotoZOOM]

No, I didn't. What's difference between QML Item and QWidget*?
If you can obtain QTextInput QWidget pointer (and you can), than it'll be work.

[aabc]

I try it and it din't work

[rotoZOOM]

Ok, as soon as I have time I'll check it.

[aabc]

Thanks.
I'll wait

you can also try maliit. Its a full framework for input methods. Has virtual keyboards also. I think they have QML keyboards as well now.

[aabc]

What is maliit ?
