QML keyboard keys unfunctionality

[qcoderpro]

Hi,

Why are the Plus and Minus keys caught and working as expected but other keys (the arrows) are not working nor do they cause no effect on the program, please?

import QtQuick
import QtQuick.Controls

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    
    Rectangle {
        id: square
        width: 100; height: 100
        anchors.centerIn: parent
        color: "green"
        focus: true
        
        Keys.onPressed:(event)=>{
                           switch(event.key) {
                               case Qt.Key_Plus:
                               square.scale += 0.2
                               break;
                               
                               case Qt.Key_Minus:
                               square.scale -= 0.2
                               break;
                               
                               case Qt.Key_Up:
                               square.y -= 8
                               break;
                               
                               case Qt.Key_Down:
                               square.y += 8
                               break;
                               
                               case Qt.Key_Right:
                               square.x += 8
                               break;
                               
                               case Qt.Key_Left:
                               square.x -= 8
                               break;
                           }
                       }
    }
}

Hi @qcoderpro,

You need to remove anchors.centerIn: parent.
