Регулярно приходится писать и ревьюить код, где используется PySide2-6. Заметил, что в подавляющем большинстве случаев настройка создаваемых базовых виджетов происходит через методы. Думаю, всем знаком такой способ. Простой пример с кнопкой: button = QPushButton("Click Me") button.setMinimumWidth(300) button.setFlat(True) button.setStyleSheet("font-size: 20pt") button.setToolTip("Super Button") button.clicked.connect(lambda: print("Button clicked")) Но есть и альтернативный способ - настройка через свойства. Это просто ключевые аргументы конструктора класса. Хоть они и не указаны в документации как аргументы, но они есть) Этот код делает тоже самое но с помощью Property button = QPushButton( "Click Me", minimumWidth=300, flat=True, styleSheet="font-size: 20pt", toolTip="Super Button", clicked=lambda: print("Button clicked"), ) Где это может быть полезно ▫️ Это выглядит более аккуратно и коротко, уже повод использовать ▫️ Может использоваться в заполнении лейаута, когда нам не нужно никакое другое взаимодействие с виджетом и поэтому сохранять его в переменную не требуется. Например, лейбл или кнопка. widget = QWidget(minimumWidth=400) layout = QHBoxLayout(widget) layout.addWidget(QLabel("Button >", alignment=Qt.AlignRight)) layout.addWidget(QPushButton("Click Me", clicked=lambda: print("Button clicked"))) widget.show() Либо так widget = QWidget(minimumWidth=400) layout = QHBoxLayout(widget) for wd in ( QLabel("Button >", alignment=Qt.AlignRight), QPushButton("Click Me", clicked=lambda: ...) ): layout.addWidget(wd) widget.show() ▫️ Можно хранить настройки в каком-то конфиге или генерировать на лету, после чего передавать как kwargs. kwargs = {"text": "Hello " * 30, "wordWrap": True} my_label = QLabel(**kwargs) Как получить полный список доступных свойств? Эта функция распечатает в терминал все свойства виджета и их текущие значения def print_widget_properties(widget): meta_object = widget.metaObject() for i in range(meta_object.propertyCount()): property_ = meta_object.property(i) property_name = property_.name() property_value = property_.read(widget) print(f"{property_name}: {property_value}") #tricks#qt
