Question

pySide2组合框与pyqt5组合有很大不同吗？

这是我的qml，在同一个foder中我有两个python文件，一个有pyqt5绑定，一个有pySide，大多数其他东西我没有问题绑定，但我在使用组合框时出错了。

import QtQuick 2.10
import QtQuick.Controls 2.1
import QtQuick.Window 2.2
import QtQuick.Controls.Material 2.3


ApplicationWindow {
    id: applicationWindow
    Material.theme: Material.Light
    title: qsTr("Test Invoke")
    visible: true

    width: 600
    height: 500

    ComboBox {
        id: comboBox
        width: 200
        model: Manager.stations
    }
}

pyqt5只需要这个

import sys
import os

from PyQt5.QtCore import QObject, QUrl, Qt, pyqtSlot, pyqtSignal,    pyqtProperty
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQml import QQmlApplicationEngine
from PyQt5 import QtGui


my_list = ['here','is','my','list']


class Manager(QObject):
    stationsChanged = pyqtSignal()

    def __init__(self):
        QObject.__init__(self)
        self.m_stations = []
       # self.m_currentStation = ""
        #self.m_currentValue =0


    @pyqtProperty(list, notify=stationsChanged)
    def stations(self):
        return self.m_stations

    @stations.setter
    def stations(self, val):
        if self.m_stations == val:
            return
        self.m_stations = val[:]
        self.stationsChanged.emit()


    def list_fill(self):       
        self.stations = my_list

if __name__ == "__main__":
    os.environ["QT_QUICK_CONTROLS_STYLE"] = "Material"
    app = QApplication(sys.argv)

    engine = QQmlApplicationEngine()
    manager = Manager()
    ctx = engine.rootContext()
    ctx.setContextProperty("Manager", manager)
    engine.load('main.qml')
    if not engine.rootObjects():
        sys.exit(-1)
    app.setWindowIcon(QtGui.QIcon('ico.png'))
    manager.list_fill()
    sys.exit(app.exec_())

和pySide2是：

import sys
import os

from PySide2.QtCore import Qt, QObject, Signal, Slot, Property
from PySide2.QtWidgets import QApplication
from PySide2.QtQml import QQmlApplicationEngine
 my_list = ['here','is','my','list']
class Manager(QObject):
    currentValueChanged = Signal()
    stationsChanged = Signal()
    def __init__(self):
        QObject.__init__(self)
        self.m_stations =[]


    def get_stationsChanged(self):
        return self.m_stations

    def set_stationsChanged(self, val):
        if self.m_stations == val:
            return
        self.m_stations = val[:]
        self.stationsChanged.emit()   

    def list_fill(self):

        self.stations = my_list

    currentValue = Property(list, get_stationsChanged, set_stationsChanged, notify=stationsChanged)    

if __name__ == "__main__":
    os.environ["QT_QUICK_CONTROLS_STYLE"] = "Material"
    app = QApplication(sys.argv)

    engine = QQmlApplicationEngine()
    manager = Manager()
    ctx = engine.rootContext()
    ctx.setContextProperty("Manager", manager)
    engine.load('main.qml')
    if not engine.rootObjects():
        sys.exit(-1)
    manager.list_fill()
    sys.exit(app.exec_())

我很确定我在pySide2上分配属性时会出错，但我不知道如何纠正它，我没有得到任何错误或任何错误，所以我很难找到答案，或者至少提示可能有问题。

PyQt5工作正常，但是pyside2没有填充组合框，或提供有关它为什么不这样做的任何信息。

PySide2传递列表属性来模型ComboBox
