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

2013 GPU mining = turning $3 of electricity into $600+ per day” Back in 2013 a simple GPU rig could mine: 0.5–1 BTC per day 0.5 BTC today = ~$18,500 1 BTC today = ~$37,000 Mining was one of the highest ROI opportunities ever seen in the digital age. People who mined early didn’t just make money — They secured freedom long before the rest of the world woke up. #BitcoinMining#BTC#CryptoHODL#MiningHistory

🚀 Bhutan's Bitcoin Mining Activities May Have Slowed Amid Economic Pressures Bhutan may have halted or reduced its Bitcoin mining operations after selling 70% of its Bitcoin holdings. According to Foresight News, this move contrasts with other major institutions and sovereign nations that are increasing their cryptocurrency and gold reserves. Bhutan's hydropower is reportedly being redirected to supply electricity to neighboring India rather than being used for Bitcoin mining. Economic pressures, along with declining Bitcoin prices, increased network difficulty, and halving pressures, are squeezing mining profitability. As of now, Druk Holding and Investments, the sovereign wealth fund managing Bhutan's Bitcoin assets, has not publicly commented on any asset transfers or the status of its mining operations. #Bhutan#Bitcoin#Cryptocurrency#BitcoinMining#Hydropower#EconomicPressure#SovereignWealthFund#MiningProfitability#India#DigitalAssets

🚀 AI TRENDS | Bitcoin Mining Centralization and Edge AI Market Growth Projected Bitcoin mining is anticipated to become increasingly centralized, according to Alex Thorn, head of Galaxy Research. According to NS3.AI, Thorn's insights suggest a shift in the mining landscape, potentially impacting the decentralization that has been a hallmark of the cryptocurrency. Meanwhile, the edge AI market is expected to experience significant growth. Grand View Research forecasts that the market will expand from approximately $25 billion in 2025 to $119 billion by 2033, indicating a trend towards more localized AI applications. #BitcoinMining#Centralization#EdgeAI#MarketGrowth#Decentralization#AITrends#GalaxyResearch#NS3AI#GrandViewResearch#LocalizedAI#BTC
