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

📢 Breaking News 🚨 💥 Critical infrastructure damaged in Dnipro, Ukraine! 💔 🏢 Sergey Lysak, Head of the Dnipropetrovsk Regional Military Administration, just revealed in his Telegram channel that a vital infrastructure object in Dnipro has been severely impacted. Reports of multiple explosions in the city were earlier covered by local media outlets. 🔍 The extent of the damage is still being assessed, but the aftermath of the attack has resulted in the destruction of several buildings and a gas pipeline in Marganets, located in the Nikopol district of Dnipropetrovsk Oblast. 🌍 These strikes on Ukrainian infrastructure began on October 10th, just two days after the terrorist attack on the Crimean Bridge. Russian authorities believe that Ukrainian intelligence agencies are behind these acts of aggression. The targets include energy facilities, defense industries, military headquarters, and communication networks across the country. 🔔 Ukrainian regions have been placed on high alert since then, with occasional nationwide air raid sirens sounding, reminding citizens of the constant threat. ⚠️ Stay tuned for more updates as the situation unfolds. Let's hope for a swift resolution to this devastating situation. 🙏🇺🇦#BreakingNews#Ukraine#Dnipro#InfrastructureDamage https://dcweekly.org/2023/09/23/underhanded-attacks-damaged-infrastructure-raises-concerns-in-dnipro/ Subscribe to @BadVolfNews

🚀 Iran's Nuclear Concessions Could Be Key to U.S. Strategy, Citic Securities Says Citic Securities stated on April 12 that if Iran were to abandon uranium enrichment, it would represent a significant achievement for the U.S., particularly for U.S. President Donald Trump, who could use it to appease domestic concerns. According to Jin10, the ongoing conflict has already negatively impacted the midterm elections, necessitating a swift resolution. Since the Iranian Islamic Revolution, the U.S. has lost control over Iran's nuclear capabilities, a challenge that has persisted through multiple U.S. presidencies, affecting America's Middle East strategy. The political impact of Iran's potential nuclear disarmament is seen as more significant than the indirect effects of oil prices and inflation on elections. Consequently, the Trump administration might consider compromises on issues like control over the Strait of Hormuz. From Iran's perspective, the conflict has demonstrated that blocking the strait and threatening Middle Eastern infrastructure are powerful leverage tools, potentially more impactful than nuclear threats. These actions, which can be executed with low-cost drones, pose significant risks to the U.S. and global economies, providing Iran with a strategic counterbalance. Repeated near-escalations to large-scale infrastructure damage suggest that the likelihood of extreme war escalation is low, reducing the chances of extreme oil prices, severe recession, or stagflation. #Iran#NuclearConcessions#USStrategy#CiticSecurities#DonaldTrump#UraniumEnrichment#MiddleEastStrategy#IranUSRelations#StraitOfHormuz#OilPrices#Inflation#PoliticalImpact#TrumpAdministration#IranianLeverage#GlobalEconomy#InfrastructureDamage#WarEscalation#OilPrices#Stagflation
