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

🌎 Deep inside Mount Rainier, rare mineral caves called "Paradise Ice Caves" form as flowing air carves tunnels through compacted mountain ice, creating shimmering blue chambers that slowly change shape with the seasons. ✨ #geology⚡#glaciers⚡#minerals 👉subscribe Interesting Planet

🌎 Powerful enough to move mountains, glaciers shaped entire continents. As they advanced, their slow, grinding ice carved out valleys, lakes, and fjords still visible today. ✨ #geology⚡#glaciers⚡#landscapes 👉subscribe Interesting Planet

🌎 Glacial ice cores are frozen natural records of Earth’s past atmosphere. As snow compacts into ice, it traps tiny air bubbles that preserve ancient air. Scientists analyze these bubbles to measure past greenhouse gas levels, revealing climate changes that go back over 800,000 years. ✨ #geology⚡#climatehistory⚡#glaciers 👉subscribe Interesting Planet

🌎 In the heart of the Torres del Paine National Park in Chile, the Valle del Francés or "French Valley" mystifies visitors with its eerie groaning noises. The sounds come from glaciers cracking and shifting above, sometimes echoing like distant thunder across the silent rocky landscape—a wild reminder of Earth's restless, mysterious forces at work. ✨ #mysteries⚡#glaciers⚡#Chile 👉subscribe Interesting Planet

🌍 Water trapped as snow and ice in the Himalayas slowly melts each spring, feeding rivers that bring life to billions across Asia. This seasonal meltwater is key to the region’s water cycle. ✨ #hydrology⚡#rivers⚡#glaciers⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Antarctica is home to “blue ice” areas where strong winds strip away snow and expose centuries-old glacier ice, creating shimmering fields that reflect nearly as much sunlight as fresh snow. ✨ #glaciers⚡#Antarctica⚡#polar⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 In Antarctica’s Dry Valleys, glaciers flow slowly over bare rock and create icy waterfalls called “ice falls,” frozen in mid-cascade for years in the planet’s coldest, driest desert region. ✨ #glaciers⚡#Antarctica⚡#polar⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 In Antarctica’s McMurdo Dry Valleys, some glaciers create striking red waterfalls called “Blood Falls.” The color comes from iron-rich water oxidizing as it flows out of the ice. ✨ #glaciers⚡#polar⚡#Antarctica⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Some Antarctic glaciers can move several meters in a single day, driven by gravity and melting underneath. These "ice rivers" shape the landscape faster than most people imagine. ✨ #glaciers⚡#polar⚡#Antarctica⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍
