Ring of Fire made by Israel in #Beirut a few minutes ago. This could be you and you'd STILL be silent.

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

It’s past midnight in #Beirut, and our "shelter" homes in the capital trembled as if there were no tomorrow—courtesy of the terrorist entity, Israel. Location: Chiyah area, Beirut, Lebanon.

Under the world’s complicit silence, Israel continues to flatten clearly residential areas in #Beirut’s southern suburbs. These aren’t military targets. They’re homes. Lives. Futures. This is no accident; it’s a calculated erasure, making sure families have nothing to return to, even if the war ends. This was at 8:00 am today.

Qassem writes about saving this baby in last night's attack by Zionist Israel on the central #Beirut: "This child was lying right here, on the remaining piece of the ceiling. When I reached him, I couldn't believe he could still be alive. But when I saw his eyes looking up at me, and how he grabbed onto me, completely in shock, I didn't know what to feel. This child will grow up, and with him, so will the hatred for this savage entity."

Terrorist Israel issued a warning to evacuate certain areas in #Beirut suburbs. Who will issue a warning for their illegal colonial settlers to RUN?
