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

🚀 Iran Nuclear Talks Fail as Tensions Impact Crypto Markets U.S. Vice President Vance announced that after 21 hours of negotiations, no agreement was reached with Iran, which refused to abandon its nuclear weapons program. According to BlockBeats, U.S. President Donald Trump had previously warned that failure in talks would lead to 'total destruction' of Iran. The ongoing conflict has caused volatility in the crypto market for weeks, compounded by tariff disputes, with Bitcoin dropping below $70,000 earlier this month. Analysts had predicted that a successful agreement could push Bitcoin to $80,000, while a breakdown might see it fall to $65,000. On the bullish side, data from on-chain wallets indicate that the largest Bitcoin holders, known as whales, have continued to buy during the peak of geopolitical turmoil rather than sell. Their reasoning is that if the conflict escalates, disrupting oil supplies from the Persian Gulf, rising oil prices and inflation could delay Federal Reserve rate cuts, benefiting scarce assets like Bitcoin and gold. Conversely, Peter Schiff, a gold trader and long-time Bitcoin skeptic, argues that as tensions rise, investors will flee Bitcoin for gold. Schiff predicts a Bitcoin 'collapse,' asserting that gold is the only true safe haven during wartime, and suggests that insiders may be profiting from market fluctuations driven by conflict news. If Trump follows through on his 'total destruction' threat, both stock and crypto markets are likely to experience simultaneous sell-offs. In terms of future developments, Vice President Vance maintained a firm stance at a press conference but did not rule out further negotiations. The Iranian parliamentary speaker demanded a ceasefire in Lebanon and the unfreezing of assets before engaging in formal talks. For Bitcoin traders, the next 72 hours hinge on two critical issues: whether a ceasefire agreement can be sustained and if Trump will escalate the conflict. Meanwhile, whale wallets continue to buy at current prices, indicating that some large investors are betting on stabilization of the situation. #IranNuclearTalks#CryptoMarket#Bitcoin#GeopoliticalRisk#Trump#OilPrices#Inflation#Gold#MarketVolatility#WhaleInvesting#MiddleEastConflict#Lebanon#USPolitics#BTC
