PySide2 QQmlApplicationEngine No Window

ruchitinfushion

Hi,
I am trying to run below code inside Maya, it runs without any error but still engine window is not visible. Tell me what's wrong or missing in code ??

ball. py

from PySide2.QtCore import QObject, QUrl, Slot
from PySide2.QtQml import QQmlApplicationEngine
from PySide2.QtQuick import QQuickWindow
import maya.cmds as mc

class Ball(QObject):
    def __init__(self):
        QObject.__init__(self)

    @Slot(int) 
    def add(self, arg1):
        mc.polySphere(r=arg1)
        
engine = QQmlApplicationEngine()
ball = Ball()
engine.rootContext().setContextProperty("ball", ball)
engine.load("E:/code/ball.qml")

ball.qml

import QtQuick 2.3
import QtQuick.Controls 1.2

ApplicationWindow {
    id: itemID
    visible: true
    width:480
    height:320
    color: "whitesmoke"

    Slider {
        id: radiusSliderID
        x: 214
        y: 141
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter
        stepSize: 1
        maximumValue: 20
        minimumValue: 1
        value: 1
    }

    Text {
        id: radiusValueID
        x: 218
        y: 194
        text: radiusSliderID.value
        font.bold: true
        anchors.horizontalCenter: parent.horizontalCenter
        font.pixelSize: 30
    }

    Button {
        id: sphereBtnID
        x: 208
        y: 262
        width: 80
        height: 30
        text: qsTr("Create Sphere")
        anchors.horizontalCenter: parent.horizontalCenter
        onClicked: {
            ball.add(radiusSliderID.value)
        }
    }

}

Have you doublechecked how things should be run inside Maya?

I suggest you try running the code as a standalone Python QT app first. For that, your code will need to also instantiate a QApplication object and then run the _exec method on it. That may actually be the reason why you're seeing nothing...
