How to read a text from a text field from c++

Question

I have a text field and a button purely designed in c++(without importing a qml doc). How do i read the text from the text field when I click the buton.

I am unable to find a function associated for that.

Are the button and the textfield QObjects? – Theolodis Nov 19 '13 at 09:25 — Theolodis, Nov 19 '13 at 09:25
Yes they are inherited by Qobject – DesirePRG Nov 19 '13 at 09:33 — DesirePRG, Nov 19 '13 at 09:33

To hook up the button to a method, use the following code:

button = new Button();
texField = new TextField();

connect(button, SIGNAL(clicked()), this, SLOT(onClicked());

Then define the onClicked slot as so:

void ClassName::onClicked() {
    qDebug() << textField->text(); //print the textField's text
}

For this to work, this method has to be marked in the class as a Q_SLOT and the object itself must be marked as a Q_OBJECT.

The question is about QML in which C++ doesn't have direct access to UI elements, so `textField` is not available in the C++ by default. – Isaac Jul 31 '15 at 11:39
Actually, he said that the button was designed in C++. – Konrad Lindenbach Aug 10 '15 at 16:40
Oh, Sorry. The `qml` tag on the question misled me. – Isaac Sep 04 '15 at 21:09
