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

🚀 Trump Reaffirms Iran's Nuclear Ambitions as a Red Line U.S. President Donald Trump reiterated his stance on Iran's nuclear ambitions, emphasizing it as a red line. According to BlockBeats, Trump stated that he received a comprehensive briefing from Vice President Vance, Special Envoy Whitcoff, and Kushner regarding the meeting in Islamabad. The discussions with Iran extended from early morning until late at night, lasting nearly 20 hours. Trump expressed that while he could elaborate on the meeting's details and the numerous achievements, the critical issue remains Iran's unwillingness to abandon its nuclear ambitions. He noted that the consensus reached in many areas was preferable to continuing military actions until the end. However, he stressed that these agreements are insignificant compared to the risk of nuclear power being in the hands of unpredictable individuals. Trump reiterated his long-standing position that Iran will never possess nuclear weapons, a stance he has maintained for many years. #Trump#Iran#NuclearAmbitions#RedLine#USPolitics#InternationalRelations#Diplomacy#NuclearWeapons#MiddleEast

🚀 Polymarket Predicts WTI Crude Oil Price Surge by 2026 The probability of WTI crude oil reaching $110 by April 2026 has significantly increased on Polymarket, now standing at 67%, with a 13% rise in the last hour and a 20% increase over 24 hours. According to Odaily, the total trading volume for this event contract has surpassed $24 million. The contract stipulates that if the highest price of any one-minute candlestick for WTI crude oil futures during April 2026 equals or exceeds the listed price, the market will be deemed a 'yes'; otherwise, it will be a 'no'. Previously, the March WTI crude oil price prediction contract required the official settlement price of the active month contract on any trading day at the Chicago Mercantile Exchange to meet or exceed the listed price by the last trading day of March 2026 for a 'yes' outcome. U.S. President Donald Trump announced today that the U.S. Navy, the world's most powerful naval force, will begin blocking any vessels attempting to enter or exit the Strait of Hormuz. He also ordered the Navy to search and intercept any ships that have paid transit fees to Iran in international waters. Those who have paid such fees will not be allowed safe passage on the high seas, and efforts will begin to destroy Iranian mines in the strait. Trump warned that any Iranian who fires upon peaceful vessels will face severe consequences. He stated that Iran knows how to end the war that has devastated their country, noting the loss of their navy, air force, and defense systems, as well as the deaths of leaders including Khamenei, all due to their nuclear ambitions. The blockade is set to begin with other countries joining in, ensuring Iran does not profit from illegal extortion. Iran seeks money and, more importantly, nuclear weapons. #WTICrudeOil#OilPricePrediction#Polymarket#TradingVolume#April2026#USNavy#StraitOfHormuz#Iran#Trump#NuclearAmbitions#InternationalSecurity
