将Qt Design Studio QML与PySide2一起使用

Question

我是Qt设计师工作室的新手。我刚刚在Qt Design Studio中创建了一个简单的按钮，我正在尝试将QML文件与PySide2一起使用，但是我遇到了多个导入错误。是否有一种特定的方法可以使用PySide2实现Qt Design Studio qml文件

项目名称是我在Qt设计工作室中创建的Demo

演示项目结构：

   Demo.qml
   Demo.qmlproject
   Demo.qmlproject.qtds
   imports
   qtquickcontrols2.conf
   Screen01.ui.qml

PySide2项目结构（main.py文件包括代码）：

   Demo.qml
   Demo.qmlproject
   Demo.qmlproject.qtds
   imports
   qtquickcontrols2.conf
   Screen01.ui.qml
   main.py

main.py：

from PySide2.QtWidgets import QApplication, QMainWindow
from PySide2.QtQuick import QQuickView
from PySide2.QtCore import QUrl
from imports import QtQuick
app = QApplication([])
view = QQuickView()
url = QUrl("Screen01.ui.qml")
view.engine().addImportPath("imports")
view.setSource(url)
view.show()
app.exec_()

错误：

module "QtStudio3D" is not installed 
module "Qt.SafeRenderer" is not installed 

Screen01.ui.qml

import QtQuick 2.12
import Demo 1.0
import QtQuick.Controls 2.3

Rectangle {
    width: Constants.width
    height: Constants.height

    color: Constants.backgroundColor

    Button {
        id: nameButton
        x: 136
        y: 227
        text: qsTr("Button")
    }
}

Answer 1

使用PyQt和Qt设计器创建UI

Answer 2

对于ppl在谷歌搜索中的绊脚石，我得到了一个主窗口来正确显示：

import sys
import os

from PySide2.QtCore import Qt, QObject, Signal, Slot, Property
from PySide2.QtGui import QGuiApplication
from PySide2.QtQml import QQmlApplicationEngine

if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
     
    engine = QQmlApplicationEngine()
    engine.addImportPath("imports")
    print(engine.importPathList() )
    engine.load('qttest2.qml')
    
    if not engine.rootObjects():
        sys.exit(-1)

    sys.exit(app.exec_())

文件qttest2.qml来自qt design studio，包含（必须为主窗口手动编辑）：

import QtQuick 2.12
import QtQuick.Layouts 1.3
import qttest2 1.0
import QtQuick.Controls 2.12

ApplicationWindow {
  visible: true
  width: 800
  height: 500
  Item {
    width: Constants.width
    height: Constants.height

    Screen01 {
    }
  }
}
