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

Please do not curse the victims of the American fires. There are many innocent civilians and pro-Palestinian people. Those elites had already fled before the fires came. #LosAngeles

This is absolutely disgusting and heartbreaking. Homeless addicts on Skid Row in LA are using innocent dogs to test their drugs for fentanyl. These poor animals are being fed deadly substances, abused, neglected, sold for drugs, and thrown away like trash. Volunteers from Starts With One Today are risking their lives to rescue these dogs with zero support from the city. How has Mayor Karen Bass and LA leadership let this horror continue? Animals are suffering and dying in plain sight while officials do nothing. This is pure cruelty. Where is the outrage? Where is the action? #SaveSkidRowDogs#AnimalAbuse#LosAngeles 🔹👉🏻@SherriTenpenny

PERFECT RING FORMED OVER LOS ANGELES This appeared high above L.A. just after dusk. A bright linear trail stretched across the sky — and around it, a smooth circular arc expanded and held its shape. The symmetry is what stands out. A straight line through the center. A clean curve wrapping around it. It lingered long enough for people across the city to stop and stare. Los Angeles, California. Did you catch this from where you are? MrMBB333 👇 Drop your city. #MrMBB333#SkyWatch#LosAngeles

As #LosAngeles burns and #firefighters face a severe water crisis, criticism is mounting against #billionaires Stewart and Lynda #Resnick, whose $13B agricultural empire consumes more water than LA and SF combined. #PalisadesWildFire
