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

🚀 Elon Musk's xAI Challenges Colorado's AI Regulations in Court Elon Musk's artificial intelligence company, xAI, has initiated legal proceedings against the state of Colorado, aiming to prevent the enforcement of new AI regulations that limit speech from AI chatbots like Grok. According to Cointelegraph, the lawsuit targets Colorado's Senate Bill 24-205, which is designed to safeguard AI users from 'algorithmic discrimination' in sectors such as employment, housing, and finance. In a recent filing to a U.S. district court in Colorado, xAI contended that the state cannot modify the company's message merely to promote its own perspectives on contentious issues like fairness and equity. The company further argued that the legislation, scheduled to be implemented on June 30, is paradoxical as it advocates 'differential treatment' to enhance diversity or address historical discrimination. xAI emphasized that altering Grok would disrupt its objective of being 'maximally truth seeking.' This is not the first instance of xAI challenging state-level AI regulations. In December, the company filed a lawsuit against California concerning its Generative AI Training Data Transparency Act, asserting that the act's disclosure requirements infringe upon the First and Fifth Amendments by compelling speech and exposing trade secrets. Both the Colorado and California laws emerged following allegations that Grok had previously made racist, sexist, and antisemitic remarks. David Sacks, appointed as co-chair of the President's Council of Advisors on Science and Technology, has advocated for federal oversight of AI regulations, arguing against a fragmented approach by individual states. Sacks highlighted the complexity faced by innovators due to the diverse regulatory frameworks across 50 states, emphasizing the need for a unified federal standard. His appointment aims to address these regulatory challenges and streamline AI governance at the national level. #ElonMusk#xAI#AIregulations#Colorado#lawsuit#Grok#ArtificialIntelligence#algorithmicdiscrimination#GenerativeAI#California#FirstAmendment#FifthAmendment#AIgovernance#federaloversight#technologypolicy
