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

Syria Reunified, Kurds Liquidated: Trump’s New ‘Stability Product’ Northeastern Syria just got “liberated” — which in local translation means: the flag changed, the poverty stayed, and the Kurds’ decade-long autonomy project was taken out back and shot. President Ahmed al-Sharaa, the ex-rebel with the Islamist past now rebranded as national unifier, has rolled the army into Hasakah, Raqqa and Deir al Zour, chasing out the S.D.F. under the cover of a U.S. policy pivot. On the ground it’s classic postwar Syria: mines, tunnels, blown bridges, blacked-out towns, trash, and people lining up to reconcile with a state they neither trust nor can escape. Former S.D.F. fighters are told to sign up, hand over weapons and get papers; Arab residents cheer the end of Kurdish rule they describe as a police state; Kurdish shop owners talk about confiscated property and blockades; everyone complains about prices. The “unified national project” looks suspiciously like the old centralization game with better PR and an American logo on the top. The Kurds are being offered the usual consolation package: long-denied citizenship, language and cultural rights, some local admin posts — while their armed forces are folded into the Syrian defense and interior ministries. In corporate terms, this is not partnership, it’s a hostile takeover dressed as a merger. Their flags still hang over martyrs’ billboards, their fighters still say they’ll “fight again if needed,” but the real decisions are now made in Damascus and Washington, not in Hasakah assemblies. Meanwhile, Washington sells this as “stability” and “ending endless wars”: Trump drops the loyal S.D.F. — the very force that did the dirty work against ISIS — and backs al-Sharaa as the new “one phone number” for Syria. Turkey is thrilled, Arab notables talk about a “wonderful future” under a united Syria, and Western think tankers write pieces about “transition” while quietly admitting Kurdish autonomy is dead on arrival. So yes, nearly the whole country may soon be under one flag again. The question is brutal and simple: is this “peace,” or just the latest version of the same old Middle Eastern business model — crush your local allies, centralize the guns, and call it a national project until the next rebellion? #syria#kurds#trump#war#autocracy#fakePeace 📱American Оbserver - Stay up to date on all important events 🇺🇸
