How do I do to trigger a collision among two rectangles?

[Cold_Distance]

Hi, I don't know how to do a collision among two rectangles. I was searching for some day but I don't see any clear example that guides me to do it in a simple program.

One of the rectangle moves automatically, and the other is controlled by the user. I will put the code I wrote:

CoheteAuto.qml

import QtQuick 2.3

Item {
    id: root

    Rectangle {

        id: contcohete
        width: 78
        height: 151
        color: "#00000000"

        Image {
            id: imacohete
            anchors.fill: parent
            source: "images/cohete.png"
        }

        MouseArea {
            id: clicacohete
            anchors.fill: parent
            onClicked: anim.start()
        }

        transitions: [
            Transition {
                to: anim.start()
            }
        ]


    }

    ParallelAnimation {
        id: anim

        NumberAnimation {
            target: contcohete
            properties: "y"
            to: 20
            duration: 5000

        }
        NumberAnimation {
            target: contcohete
            properties: "x"
            to: 160
            duration: 5000
        }

        onStopped: anim2.start()
    }

    SequentialAnimation {
        id: anim2
        NumberAnimation {
            target: contcohete
            properties: "y"
            to: 100
            // 60% of time to travel up
            duration: 10000
        }
        NumberAnimation {
            target: contcohete
            properties: "x"
            to: 400
            // 40% of time to travel sideways
            duration: 10000
        }
    }
}

CuadroManual.qml

import QtQuick 2.3

Item{
    id: root


    Rectangle {
        id:cuadrado
        width: 150
        height: 150
        color: "#53a135"
        border.color: "#61e361"

    }

    // A partir de aquí podemos empezar a manipular el 'cuadrado' desde el teclado
    focus: true
    //Keys.onLeftPressed: cuadrado.x -= 8
    //Keys.onRightPressed: cuadrado.x += 8
    //Keys.onUpPressed: cuadrado.y -= 8
    //Keys.onDownPressed: cuadrado.y += 8
    Keys.onPressed: {
        switch(event.key) {
        case Qt.Key_Plus:
            cuadrado.scale += 0.2
            break;
        case Qt.Key_Minus:
            cuadrado.scale -= 0.2
            break;
        case Qt.Key_A:
            cuadrado.x -= 8
            break;
        case Qt.Key_D:
            cuadrado.x += 8
            break;
        case Qt.Key_W:
            cuadrado.y -= 8
            break;
        case Qt.Key_S:
            cuadrado.y += 8
            break;
        }
    }
}

main.qml

import QtQuick 2.3
import QtQuick.Window 2.2

Window {
    visible: true
    width: 800
    height: 600

    Image {
        id: fondoventana
        anchors.fill: parent
        source: "images/campo.jpg"
    }

    CoheteAuto{
        id: cohete
        x: 65
        y: 215

        Behavior on x{

        }
        Behavior on y{

        }

    }

    CuadroManual{
        id: cuadro
        x: 500
        y: 300

    }
}

It doesn't mind if the code is not orthodox, the only thing I want is to collide the two rectangles.

I think u follow rectangles corner point so u know where is the rectangles. And when locations are collision, u can alert something.
