Python 与 QML (Qt-Quick) 配合得很好吗 [关闭]

Python与QML（Qt-Quick）是一对很好的配合。Python是一种简单易学的编程语言，而QML是一种用于创建动态用户界面的现代化技术。两者结合使用可以实现强大的图形化应用程序。下面将介绍一些Python与QML配合的案例和示例代码。

python
import sys
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQuick import QQuickView
if __name__ == "__main__":
    app = QApplication(sys.argv)
    view = QQuickView()
    view.setSource(QUrl.fromLocalFile("main.qml"))
    view.show()
    sys.exit(app.exec_())

python
import sys
from PyQt5.QtCore import QObject, pyqtSlot, pyqtProperty
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQml import QQmlApplicationEngine
class Backend(QObject):
    def __init__(self, parent=None):
        super().__init__(parent)
        self._text = ""
    @pyqtProperty(str)
    def text(self):
        return self._text
    @text.setter
    def text(self, value):
        self._text = value
    @pyqtSlot()
    def updateText(self):
        self.text = "Hello from Python!"
if __name__ == "__main__":
    app = QApplication(sys.argv)
    engine = QQmlApplicationEngine()
    backend = Backend()
    engine.rootContext().setContextProperty("backend", backend)
    engine.load("main.qml")
    sys.exit(app.exec_())

python
import sys
from PyQt5.QtCore import QObject, pyqtSlot
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQml import QQmlApplicationEngine
class Calculator(QObject):
    @pyqtSlot(int, int, result=int)
    def add(self, a, b):
        return a + b
if __name__ == "__main__":
    app = QApplication(sys.argv)
    engine = QQmlApplicationEngine()
    calculator = Calculator()
    engine.rootContext().setContextProperty("calculator", calculator)
    engine.load("main.qml")
    sys.exit(app.exec_())
