pyside6-metaobjectdump

pyside6-metaobjectdump 是一个命令行工具。它扫描 Python 源文件并以 JSON 格式输出要注册到 QML 的类的信息。这作为 pyside6-qmltyperegistrar 工具的输入。

该工具相当于Qt / C++中的moc工具。

它由pyside6-project工具自动运行，当传递qmllint参数时，指示它检查QML源文件。

用法

要在QML中注册的类通过QML装饰器如@QmlElement来指示。调用：

pyside6-metaobjectdump birthdayparty.py

在标准输出上生成JSON数据：
