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

Russian Defence Ministry (@mod_russia_en): ❗️Statement by Russian Defence Ministry ▪️ On March 14, at about 11.30 a.m. Moscow time, Tochka-U tactical missile was fired at a residential block of Donetsk city from the territory controlled by the Kiev nationalist regime. ▪️ The shelling of the city was carried out from the north-western direction, from the area of Krasnoarmeysk settlement, which is controlled by Ukrainian nationalist units. ▪️ As a result of the explosion of a cluster warhead in the center of Donetsk, 20 civilians were killed. Another 28 people, including children, were seriously injured and taken to medical institutions. ▪️ The use of such weapons on a town with no armed forces firing positions, i.e. deliberately targeting civilians, is a war crime. #Ukraine#Donetsk#WarCrime

How a Secluded 1984 Conference Forged Israel’s Unprecedented Influence Over US Media October 31st, 2024 By Kit Klarenberg . In the first week of January 2024, Israeli forces fired 355 bullets at a car containing a five-year-old, then shot at rescue workers who rushed to save her life. An indisputible act of murder, a definite #WarCrime – yet, per many Western media headlines, she was simply a “girl killed in Gaza.” The circumstances and perpetrators of her death, if mentioned at all, were invariably buried at the bottom of reports, well hidden from the 80% of the news-consuming public who only read headlines. In contrast, on October 15 2024, Sky News was very keen that its viewers know the names and faces of four “teenage” #IDF soldiers “killed” in a “#Hezbollah#drone attack,” humanizing and infantilizing individuals who, by mere token of their service in Israel’s military, are by definition, guilty of genocide. .....

🇺🇸#USA #US#Senator#LindseyGraham voices his fear that, due to the International Criminal Court's (#ICC) #WarCrime Charges against Israeli PM #Netanyahu, there might after all even be some adverse #legal consequences for both his own, and his country's, illegal War actions. "If they'll do this to Israel, we're next."
