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

🌍 Temperate grasslands like the Eurasian steppes can experience temperature swings of over 40°C between summer and winter, creating some of the planet’s most extreme seasonal contrasts. ✨ #grasslands⚡#savanna⚡#climate⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some savannas and grasslands support massive termite mounds reaching over 8 meters high. These structures regulate temperature and moisture, acting as tiny skyscrapers for entire insect communities. ✨ #savanna⚡#grassland⚡#biodiversity⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 In South America’s Cerrado grassland, more than 4,800 plant species are found only there. This savanna rivals the Amazon in biodiversity but is rapidly disappearing to farmland. ✨ #savanna⚡#grassland⚡#biodiversity⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some African savannas are home to "whistling thorn" trees, which grow hollow spines. Tiny ants live inside and defend the tree from animals, forming a team-up rarely seen in grassland ecosystems. ✨ #savanna⚡#grassland⚡#biodiversity⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The African savanna is so vast it supports the world’s largest land migration—over 1.5 million wildebeest travel hundreds of kilometers each year in search of fresh grass. ✨ #savanna⚡#migration⚡#wildlife⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The Serengeti savanna in Africa hosts one of the world’s largest mammal migrations—zebras cross first, followed by wildebeest, each group timing their journey to feed on different heights of grass. ✨ #savanna⚡#migration⚡#ecosystems⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Tropical savannas can burn naturally every 1–3 years, yet some species, like the baobab tree, thrive by storing water in thick trunks to survive both drought and fire. ✨ #savanna⚡#grassland⚡#adaptation⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some grassland plants grow deep roots reaching over 2 meters underground. These roots help the plants survive drought and anchor soil, making grasslands some of the most erosion-resistant landscapes. ✨ #grasslands⚡#savanna⚡#ecology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Grasslands cover about 40% of Earth’s land surface and are found on every continent except Antarctica. Some of the world’s richest soils, called mollisols, form in temperate grasslands. ✨ #grasslands⚡#savanna⚡#soil⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Seasonal fires in some savannas are so regular that certain plants have evolved to flower or sprout only after being scorched, using fire as a natural part of their life cycle. ✨ #savanna⚡#grassland⚡#fire⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some grassland fires are started by lightning and play a natural role in shaping these ecosystems. Fire clears old growth, helps seeds sprout, and maintains open habitat for many animals. ✨ #savanna⚡#grassland⚡#fire⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍
