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

Wikipedia每日一图（#March 22, 2026）https://ift.tt/EdkunCs Royal angelfish (Pygoplites diacanthus), Ras Muhammad National Park, Red Sea, Egypt. The body of the royal angelfish is moderately elongate, is very compressed and can reach a length of up to 25 centimetres (9.8 in) It's widely distributed throughout the Indo-Pacific and can be found in the Red Sea and Indian Ocean around East Africa and the Maldives, stretching to the Tuamoto Islands, New Caledonia, and Great Barrier Reef. The royal angelfish occurs at depths ranging from 0 to 80m (0 to 262 ft), in coral rich areas of lagoons, reefs, and are also often found in the vicinity of caves. It is a carnivorous species that feeds on sponges and tunicates located throughout reefs and underwater caves. They are a non-migratory species that can be found solitary, in pairs, or groups. Probably the most spectacular fish I've ever seen underwater in terms of colors. we have no FPs of the whole family Pomacanthidae (marine angelfishes).. 了解更多 . #Wikipedia每日一图
