Установить свойства виджета в PySide можно не только через соответствующие методы и конструктор класса. Можно их изменять с помощью метода setProperty по имени. btn = QPushButton("Click Me") btn.setProperty("flat", True) Это аналогично вызову btn.setFlat(True) Если указать несуществующее свойство, то оно просто создается btn.setProperty("btnType", "super") Получить его значение можно методом .property(name) btn_type = btn.property("btnType") Когда это может быть полезно? ▫️Можно просто хранить какие то данные в виджете и потом их доставать обратно widget = QWidget() widget.setProperty('my_data', 123) print(widget.property('my_data')) ▫️ Назначая эти свойства разным виджетам можно потом отличить виджеты во время итераци по ним. Например, найти все кнопки со свойством my_data="superbtn". Но ведь вместо кастомного свойства можно использовать objectName, будет тот же результат. Да, но y ObjectName есть ограничение - только строки. ▫️ Если нам потребуется не просто поиск а, например, сортировка по числу, то свойства позволяют нам это сделать. Поддерживается любой тип данных widget.setProperty('my_data', {'Key': 'value'}) widget.setProperty('order', 1) all_widgets.sort(key=w: w.property('order')) Но ведь Python позволяет всё вышеперечисленное сделать простым созданием атрибута у объекта widget.order = 1 widget.my_data = 123 Да, но я думаю что не надо объяснять почему не стоит так делать. К тому же, если у виджета нет свойства то метод .property(name) вернет None, а отсутствующий атрибут выбросит исключение. ▫️ Действительно полезное применение кастомным свойствам - контроль стилей. Здесь атрибутами не обойтись, нужны именно свойства. Дело в том, что в селекторах стилей можно указывать конкретные свойства виджетов на которые следует назначать стиль. Просто запустите этот код from PySide2.QtWidgets import * if __name__ == "__main__": app = QApplication([]) widget = QWidget(minimumWidth=300) layout = QVBoxLayout(widget) btn1 = QPushButton("Action 1") btn2 = QPushButton("Action 2") btn3 = QPushButton("Action 3", flat=True) layout.addWidget(btn1) layout.addWidget(btn2) layout.addWidget(btn3) # добавим кастомное свойство одной кнопке btn1.setProperty("btnType", "super") # добавляем стили widget.setStyleSheet( """ QPushButton[btnType="super"] { background-color: yellow; color: red; } QPushButton[flat="true"] { color: yellow; } """ ) widget.show() app.exec_() С помощью селектора мы избирательно назначили стили на конкретные кнопки. Как получить список всех кастомный свойств? Функция получения списка кастомных свойств отличается от получения дефолтных. def print_widget_dyn_properties(widget): for prop_name in widget.dynamicPropertyNames(): property_name = prop_name.data().decode() property_value = widget.property(property_name) print(f"{property_name}: {property_value}") #tricks#qt

🪐 The exoplanet 55 Cancri e, orbiting a star about 41 light-years away in the constellation Cancer, is known for its fiery dayside, reaching temperatures above 2,400°C—hot enough to melt metal. This rocky world is likely covered by a massive ocean of molten lava, and some scientists think its carbon-rich composition could even mean parts of the planet’s interior are made of diamond. ✨ #exoplanets⚡#extremes⚡#lava⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 Far from Earth, the exoplanet COROT-7b endures some of the most extreme conditions known: it orbits its star so closely that its surface reaches about 2,000°C, hot enough to melt rock. Scientists believe this heat turns the planet’s rocky crust into a vast, bubbling “lava ocean,” creating a world where rock vaporizes into the atmosphere and rains down as pebbles. ✨ #exoplanet⚡#extremes⚡#lava⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
