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

Secondo turno delle primarie #Conservatives. Dopo la rinuncia di Matthew Hancock, viene escluso lo hard brexiter Dominic Raab (con 30 voti, sotto la soglia minima di 33). Boris Johnson rimane il più euroscettico in corsa, e potrebbe accumulare la maggior parte dei voti di Raab. A sorpresa quasi raddoppia il proprio consenso Rory Stewart, che sorpassa Sajid Javid.

📰 Conservatives Who Once Railed Against Federal Agents Now Applaud Them For decades, right-wing populists have excoriated federal law enforcement, citing tragedies like Ruby Ridge and Waco as proof of government overreach. Now, under President Donald Trump, many of those same conservatives are cheering on federal agents as they crack down on immigration and unrest in cities like Minneapolis. The shift highlights how political allegiance shapes attitudes toward federal power—applauding crackdowns on adversaries while condemning them when they target allies. From Enemies to Enforcers Trump’s deployment of ICE, the Border Patrol, and the National Guard has transformed federal agents from bogeymen to heroes in the eyes of many conservatives. Critics say this reflects “motivated reasoning”—support for police action depends on who’s being targeted. When federal agents confront immigrants or minorities, conservative voices are often silent or supportive, but when they target anti-government activists, the outrage returns. The Legacy of Ruby Ridge and Waco Ruby Ridge and Waco became rallying cries for anti-government movements, fueling distrust of federal law enforcement. But today, with Trump in power, many right-wing activists have embraced federal agents as tools of law and order. The shift underscores how political power can reshape perceptions of authority. Who’s the Enemy Now? As federal agents raid homes and neighborhoods, the question is: Who decides when police action is justified? The answer seems to depend less on the law than on who’s in charge—and who’s being targeted. #Trump#Conservatives#FederalAgents#Immigration#RubyRidge#Waco#LawAndOrder 📱American Оbserver - Stay up to date on all important events 🇺🇸

#The_Critic🇬🇧📕[PDF]⬇️ #November2025 #Monthly_Magazines For learning, for free(dom). @backupofmagazines This issue dissects Britain’s political fatigue in “Follow the Leader,” charting how #Conservatives lost moral and cultural authority. Essays probe #FiscalPolicy fictions, #CultureWar fatigue, and the right’s need for artistic renewal. Features span #Trump diplomacy, Britain’s agricultural crisis, and a nostalgic defense of #Seapower. In culture, Cézanne’s southern light meets reflections on music, literature, and satire. Critics debate #Opera, #Theatre, #Books, and fine whisky—mixing wit with worry. It’s a portrait of a nation in ideological hangover. #UKPolitics#Brexit#Art#Society#ConservativeCollapse#TheCritic#Philosophy
