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

🪐 The Tarantula Nebula in the Large Magellanic Cloud is the most active star-forming region in the Local Group of galaxies, producing some of the most massive stars ever observed. Inside this cosmic web, the star R136a1 blazes with a mass over 250 times that of the Sun, pushing the boundaries of how big stars can grow before they collapse. ✨ #TarantulaNebula⚡#starformation⚡#R136a1 👉subscribe Universe Mysteries

🪐 The pulsar PSR J0537−6910, spinning an incredible 62 times per second, sits in the Tarantula Nebula of the Large Magellanic Cloud and holds the record for the fastest known "glitches." Glitches are sudden jumps in a pulsar’s rotation speed—caused by internal adjustments in these ultra-dense, spinning neutron stars—and PSR J0537−6910’s frequent glitches help scientists unlock secrets about the strange matter inside these cosmic lighthouses. ✨ #pulsars⚡#neutronstars⚡#tarantulanebula⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels

🪐 The rapidly spinning star VFTS 102, found in the Tarantula Nebula of the Large Magellanic Cloud, is one of the fastest rotating stars ever observed—spinning at over 2 million kilometers per hour. This extreme speed stretches the star into an oblate shape and may be the result of a dramatic past, possibly caused by a close encounter or collision with another star. ✨ #unusualstars⚡#tarantulanebula⚡#rotation⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels

🪐 The star VFTS 352, located in the Tarantula Nebula about 160,000 light-years away, is actually two massive stars orbiting each other so closely that their outer layers touch—creating a rare "overcontact binary." This unusual system is on the verge of merging, and both stars are so hot and bright that their shared atmosphere fuses them together, making VFTS 352 one of the most extreme examples of stellar partnership ever found. ✨ #unusualstars⚡#binaries⚡#TarantulaNebula⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels

🪐 In the Tarantula Nebula of the Large Magellanic Cloud, light from young, massive stars races outward at the universal speed limit—299,792 kilometers per second—helping illuminate vast clouds of gas across 1,000 light-years of space. Because nothing can travel faster than this speed in a vacuum, the glow we see from such stellar nurseries is always an echo from the past, showing us cosmic events exactly as they unfolded years, decades, or even millennia ago. ✨ #speedoflight⚡#tarantulanebula⚡#largemagellaniccloud⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 The star R136a1, found in the Tarantula Nebula of the Large Magellanic Cloud, is considered the most massive known star, weighing in at about 215 times the mass of our Sun. Unlike ordinary stars, R136a1 is so hot and bright that it blasts vast amounts of its own material into space, shortening its lifespan to just a few million years—an incredibly brief existence for such a cosmic giant. ✨ #unusualstars⚡#tarantulanebula⚡#stellarphysics⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
