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

🚀 Societe Generale Strategists Adjust ECB Rate Hike Expectations Societe Generale's interest rate strategists have revised their baseline scenario, according to Jin10. They now anticipate that the European Central Bank (ECB) will implement two 'preventive' rate hikes in June and September, while the economy remains resilient. This adjustment is expected to keep the 10-year German bond yield above 3% throughout 2026, preventing a significant yield curve inversion. The strategists suggest that a ceasefire and de-escalation in the Middle East could stabilize the short end of the eurozone yield curve, with market expectations for the ECB's terminal rate stabilizing around 2.50%. They also note that if German bond yields fall below 2.90%, it may present an opportunity to short duration, as they still expect the yield to reach 3.20% in the second quarter. #ECB#InterestRates#EuropeanCentralBank#EurozoneEconomy#GermanBonds#YieldCurve#RateHike#MonetaryPolicy#FinancialMarkets#SocieteGenerale

🚀 China's Fund Reports Show Decline in Q1 Returns Amid Low Interest Rates On April 10, the China Securities Regulatory Commission's official website began disclosing the first-quarter reports of public funds for 2026. According to Jin10, several money market funds managed by Debang Fund have released their latest operational updates. In the current low-interest-rate environment, the expected returns on fixed-income assets continue to decline, significantly affecting money market funds primarily invested in bond assets. The net asset value growth rate for these funds in the first quarter was generally around 0.3%, with some funds reporting quarterly performance below this threshold. Additionally, the surge in oil prices in March has heightened inflation expectations, leading to an increase in long-term yields, while a loose monetary environment supports a continued decline in short-term yields, resulting in a steepening yield curve. Funds are currently focusing on shortening duration in their management strategies. Market analysts suggest that reducing the remaining maturity can mitigate the risk of net asset value decline due to interest rate fluctuations, enhance asset liquidity, and achieve a stable risk-averse strategy, thereby strengthening the portfolio's risk resistance. #China#FundReports#Q1Returns#LowInterestRates#MoneyMarketFunds#BondAssets#Inflation#YieldCurve#MonetaryPolicy#AssetManagement#InvestmentStrategy
