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

Bitcoin Price Peak Expected in 2025 The founder of Pantera, whose Bitcoin fund saw a staggering 130,000% return, forecasts August 2025 as the peak for this cycle, anticipating a bull market in 2025 followed by a decline in 2026. He believes Bitcoin could increase tenfold over the next 5-10 years. Meanwhile, in mining news, Foundry USA Pool mistakenly refunded an erroneous transaction fee of 8.18 BTC (about $777,000), which was 91,127 times higher than normal. Additionally, Volatility Shares has applied to launch futures-based Solana ETFs, signaling potential market interest despite the absence of a current trading platform for these products. #Bitcoin#Pantera#Crypto#ETF#Solana#Mining#Forecast#BullMarket#BearMarket#Foundry#VolatilityShares#BTC#CryptoNews#Investing#MarketTrends#Blockchain#TransactionFee#Finance#Cryptocurrency #2025 #2026

Mining Project Linked to Notcoin? Emerging mining project possibly linked to The Open Builders, but not confirmed. Design resembles their work. Early supporters encouraged to invest, but caution advised due to potential volatility. Bitcoin has hit a new all-time hashrate of 1000 EH/s, with 40% concentrated in the US led by Foundry USA at 36.5% share. China still holds a significant portion of Bitcoin mining. In other news, Coinbase is considering tokenized stocks for its Base blockchain, while Ethena announces new products including an institutional synthetic stablecoin and a Telegram-based app. Phantom wallet team denies rumors of an upcoming airdrop or token launch. #Mining#Bitcoin#Cryptocurrency#Notcoin#TheOpenBuilders#Ethena#Stablecoins#PhantomWallet#COIN#Base#Funding#CryptoPayments#Investing#Hashrate#Blockchain#DeFi#CryptoNews#Tech#US#China#Foundry
