PyQt5.4. No window shown

hongquan

Hi. I try a minimal PyQt5.4 app:

https://bitbucket.org/snippets/hongquan/Kond

When I run

python3 run.y

no window shows. What did I do wrong?

Did you get any errors when you try to run it?

The following works perfectly for me on Mac OSX 10.8, Python3.4, Qt5.4:

test.qml

import QtQuick 2.2
import QtQuick.Controls 1.1

ApplicationWindow{
  width: 400
  height: 300
  visible: true
  title: qsTr("Hello")
  Label{
    text: qsTr("Hello")
    anchors.centerIn: parent
  }
}

run.py

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtQml import *
from sys import argv, exit

def createApplication():
    app=QGuiApplication(argv)
    engine=QQmlApplicationEngine(app)
    engine.load(QUrl("test.qml"))
    return app    

if __name__=="__main__":
    app=createApplication()
    exit(app.exec_())

To execute:

$ python run.py
