Qml中的PyQt5应用程序窗口出现空白屏幕

Question

我试图用PyQt5加载一个ApplicationWindow实例。我正在读它是如何做的C++，这是正确的答案。如何使用PyQt5创建这个？Python中的文档与C++有点不同。在

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQuickWindow>

int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl("qml/window/main.qml"));
QObject *topLevel = engine.rootObjects().value(0);
QQuickWindow *window = qobject_cast<QQuickWindow *>(topLevel);
window->show();
return app.exec();
}

Answer 1

非常基本的例子：

example.py：

from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQuick import QQuickView
import sys

app = QApplication(sys.argv)

view = QQuickView()
view.setSource(QUrl("example.qml"))
view.show()

app.exec()

example.qml：
