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

“Il conflitto in crescita rischia di sfociare in una guerra regionale più ampia”. Con queste parole mons. Paul S. Coakley, arcivescovo di Oklahoma City e presidente della Conferenza episcopale degli Stati Uniti (Usccb), ha chiesto agli #USAi, all’#Iran e all’intera comunità internazionale di tornare al dialogo e di percorrere ogni strada verso una pace giusta e duratura. Facendo proprie le parole di Papa #LeoneXIV – che all’Angelus di ieri ha invitato a fermare “la spirale della violenza prima che diventi una voragine irreparabile” e a promuovere “il bene dei popoli, che anelano a una convivenza pacifica, fondata sulla giustizia” – il presule ha rivolto “un appello accorato a tutte le parti coinvolte perché la diplomazia riacquisti il suo ruolo” e ha chiesto “una cessazione della spirale della violenza” e un ritorno al “coinvolgimento diplomatico multilaterale”. Mons. Coakley ha quindi invitato “i cattolici e tutti gli uomini di buona volontà a continuare le ardenti preghiere per la pace in Medio Oriente, per la sicurezza delle truppe e degli innocenti”, affidando il mondo all’intercessione di Maria, “Regina della pace”.

🇺🇸U.S. Executive Order Signals Federal Preemption in AI Policy President Donald Trump has signed a new Executive Order aimed at implementing the U.S. AI Action Plan and removing what the administration views as barriers to American leadership in AI. The Order represents the White House’s second effort to limit state-level AI regulation, following the Senate’s rejection of a proposed 10-year moratorium. It frames extensive state AI laws as a legal and strategic risk, arguing that fragmented regulation across states could undermine innovation and national competitiveness. The Order advances federal authority through three core rationales. First, it argues that AI companies must operate without burdensome, inconsistent state rules, particularly given the absence of a comprehensive federal AI law and the existence of over 1,000 state-level AI bills. Second, it targets state laws that, in the administration’s view, mandate “ideological bias” in AI systems, framing such requirements as potentially violating the Federal Trade Commission Act’s ban on unfair or deceptive practices. Third, it establishes an AI Litigation Task Force within the Department of Justice to challenge state AI laws deemed to unlawfully regulate interstate commerce, conflict with federal policy, or otherwise be unlawful in the Attorney General’s judgment. Together, these measures consolidate regulatory control at the federal level while deferring the adoption of a comprehensive national AI statute. The Executive Order positions federal enforcement and preemption as the primary tools for shaping U.S. AI governance, with significant implications for the future role of state-level AI regulation. #AIRegulation#USAI ##AIPolicy#AILaw
