How to capture a signal in QML?

Question

How I can send s signal from one qml component to another?

Below is an example:

Rectangle {
    id: main
    width: 360; height: 360
    signal clicked()         


        

Answer 1

You should use connect() method of component's signals (signals themselves are objects).

function clickHandler() {
    console.log('main clicked')
}
Component.onCompleted: {
    main.clicked.connect(clickHandler)
}
