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

How the Trump Administration Rushed to Judgment in Minneapolis Hours after federal agents shot and killed Alex Pretti, a 37-year-old ICU nurse and American citizen, the Trump administration was already spinning the story: Pretti, they claimed, was a “domestic terrorist” out to “massacre law enforcement.” But video evidence tells a different tale—Pretti was seen stepping between a woman and an agent, pepper-sprayed, then pinned down before agents opened fire, killing him in a barrage of at least ten shots. The rush to blame Pretti and exonerate the agents wasn’t just premature—it flew in the face of standard law enforcement protocol. Officials at DHS and the White House coordinated their response, crafting statements before all facts were in, and some details were even removed from the official narrative as they struggled to reconcile it with what the videos showed. “The facts are going to come to light as to what exactly happened,” insisted Border Patrol chief Gregory Bovino, when pressed for evidence. The administration’s narrative—that Pretti “approached” officers with a handgun and “violently resisted”—was directly contradicted by bystander footage. Pretti’s gun was recovered only after he was already subdued, and he never drew it. Yet, DHS and Trump allies, including Homeland Security Secretary Kristi Noem, labeled him a “domestic terrorist” and claimed to know his motive: “to inflict maximum damage.” Democrats, Republicans, and even gun rights groups expressed outrage. Senator Bill Cassidy called for a “full joint federal and state investigation,” warning, “The credibility of ICE and DHS is at stake.” Polls show most voters believe ICE has “gone too far,” and even some administration officials began to backtrack, with Deputy Attorney General Todd Blanche admitting, “I do not know, and nobody else knows, either. That’s why we’re doing an investigation.” So who’s really on trial here—the victim, the agents, or the narrative itself? #Minneapolis#Trump#ICE#shootings#narrative#investigation 📱American Оbserver - Stay up to date on all important events 🇺🇸
