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

A dolphin can make about 700 to 1000 clicking sounds per second. The clicks come from deep inside the dolphin’s head, underneath the blowhole. Scientists call this area the phonic lips or sometimes “monkey lips.” @googlefactss#mammals

There are two main groups of bats: larger, Old World, fruit-eating mega bats (Megachiroptera) and microbats (Microchiroptera). Megabats are also known as fruit bats or flying foxes and typically live in warm climates. They use their large eyes to find food in the dark and they tend to roost in trees rather than in caves, crevices, or old buildings. Microbats are generally much smaller and use echolocation to find insects. Microbats are typically found all over the world, including the U.S. Not all megabats are larger than microbats. @googlefactss#mammals#nowyouknow

A mother koala 🐨 will feed her baby her own feces known as pap. Baby koalas—or joeys—haven’t developed the intestinal bacteria 🦠 that help detoxify the highly poisonous eucalyptus leaves 🍃, which are a koala’s main diet. This process is crucial for their survival. ❤️ @googlefactss#animals#mammals

🌎 In the dense forests of Southeast Asia, the binturong uses its prehensile tail like a fifth limb—wrapping it around tree branches for balance and grip. This adaptation helps it nimbly move through the canopy and reach fruit high above the forest floor. ✨ #mammals⚡#adaptation⚡#rainforest 👉subscribe Interesting Planet

🌎 The silky anteater is the world’s smallest anteater, fitting in your hand! With dense golden fur and a prehensile tail, it climbs trees at night to slurp up ants, avoiding predators with its tiny size and camouflage. ✨ #mammals⚡#rainforest⚡#adaptation 👉subscribe Interesting Planet

🌎 In the remote forests of India, the Malabar giant squirrel can leap over 6 meters between trees. Its colorful fur blends red, purple, and orange tones, making it one of the world’s most striking mammals. ✨ #wildlife⚡#biodiversity⚡#mammals 👉subscribe Interesting Planet

🌎 In the icy landscapes of Greenland, musk oxen survive Arctic winters thanks to an incredibly dense undercoat called qiviut, which is eight times warmer than sheep’s wool. This soft fiber insulates these shaggy animals so well that snow won't melt on their backs, even in the harshest cold. ✨ #mammals⚡#adaptation⚡#arctic 👉subscribe Interesting Planet

There's an animal that smells like buttered popcorn. The binturong (Arctictis binturong), a Southeast Asian "bearcat," smells like buttered popcorn due to 2-acetyl-1-pyrroline (2-AP) in its urine, which it uses to mark territory. This chemical is the same aromatic compound produced when popcorn is popped. These arboreal, cat-like mammals are threatened by habitat loss. @googlefactss#animals#mammals#bizarre [read more....]

🌎 Every year, saiga antelopes in Central Asia undertake one of the largest mammal migrations, moving up to 1,200 kilometers across Kazakhstan and Russia. These critically endangered animals travel in herds of thousands to reach seasonal grazing areas, helping their calves survive harsh winters. ✨ #wildlife⚡#migration⚡#mammals 👉subscribe Interesting Planet 👉more Channels ​
