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

Even in the darkest times of #war, humor becomes a tool for resilience, offering brief moments of relief and a way to cope with the harsh realities. It’s a reminder that laughter, no matter how fleeting, can be a powerful act of defiance and hope in the face of adversity. #LebanonUnderAttack

The Lebanese Ministry of Health's Emergency Operations Center reported that the death toll from the Israeli assault has climbed to 2,653, with 12,360 others wounded since October 8, 2023. This staggering rise reflects the continuous bombardment and escalating violence. #Israel#Lebanon#LebanonUnderAttack

Israel has struck Beirut once again, this time targeting Mar Elias Street; the heart of the capital and one of its most densely populated areas during the war, as countless displaced families from the suburbs have sought refuge there. This relentless aggression is not just an attack on civilians; it’s a blatant violation of all norms of international law, crossing every red line. #LebanonUnderAttack #BeirutUnderAttack

Zionist Israeli Psychopaths hit a home in Ayto town in #Zgharta north #Lebanon that was housing families displaced from South Lebanon and Beirut suburbs. 25 humans in the house, the Red cross so far said that 18 are martyred. I will not share any videos or photos, as many of the women might be hijabis, and the footage shows them in heartbreaking scenes without their hijabs. #LebanonUnderAttack

Devastation in the heart of Beirut: On the night of November 17, #Israel targeted a densely populated building on the famous Mar Elias Street, setting off a massive fire that raged through the night. The building housed motor generators and an electronics shop, where lithium batteries likely fueled the inferno, adding to the chaos and destruction. #LebanonUnderAttack#WarCrimes#Beirut
