Well, the first thing you need to do is expose your QML TextField to C++. This is done with an object name property ala:

TextField {
    objectName: "myTextField"
    ...
}

Next, find this child from your C++:

QmlDocument *qml =  QmlDocument::create("asset:///my.qml");
Container *root = qml->createRootObject<bb::cascades::Container>(); //or whatever the root control is
TextField *textField = root->findChild<TextField*>("myTextField");

From then on, simply use textField->text().

We have 3 parts in this problem

First on in Qml your text area and bottom when clicked send text area to function in c++

TextField {
               id: n2
            }
  Button {
            id: button

            text: "send text"
            onClicked: {
               app.sendtext(n2.text)
            }

Second part your c++ function in your ApplicationUI to receive this text 

 QString ApplicationUI::sendtext(QString txtarea)
  {
     QString text = txtarea;
     return text;
  }

Third and final part in your ApplicationUI.h u must make this function INVOKABLE to access it in Qml

so u will need this line 

Q_INVOKABLE QString sendtext(QString txtarea);
