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

One of the main differences between frogs and toads is that frogs need to stay by water to survive, whereas toads can survive without constant access to moisture. @googlefactss#amphibians

The wood frog can hold its pee for up to eight months by recycling urea into nitrogen, a process that helps protect their cells and tissues while they hibernate and freeze solid during the winter. @googlefactss#amphibians

The world’s largest frog, the Goliath frog, is found in Equatorial Guinea and Cameroon. It is capable of growing up to 34 cm (13.4 inches) in length and can weigh over 3.2 kg (7 pounds). @googlefactss#amphibians#nowyouknow

🌎 The male pipa toad, found in South American rivers, carries dozens of eggs in pockets on its back skin. As the eggs develop, young toads emerge fully formed through openings in his skin. Each pocket can hold up to 100 eggs, making this reproduction method unique among amphibians. ✨ #animals⚡#amphibians⚡#wildlife 👉subscribe Interesting Planet 👉more Channels

🌎 The axolotl, a salamander native to Mexico, can regenerate entire limbs, spinal cord, heart tissue, and even parts of its brain. Unlike most amphibians, axolotls remain aquatic and gilled for their whole lives due to a trait called neoteny. ✨ #axolotl⚡#regeneration⚡#amphibians 👉subscribe Interesting Planet 👉more Channels

The Titicaca water frog (Telmatobius culeus) can absorb oxygen through its skin, an adaptation that helps it survive in the high-altitude waters of Lake Titicaca, where oxygen levels are low. This unique ability allows it to thrive in an environment where most other species struggle. The frog's skin is highly vascularized, increasing its efficiency at absorbing oxygen directly from the water. 💧🐸⛰️ [Read more] (Frog memes allowed here) @googlefactss #FrogFacts#TiticacaFrog#TelmatobiusCuleus#NatureScience#UniqueAdaptations#Amphibians#ItsWednesdayMyDudes If you have ideas or feedback contact us: @Googlefactss_Feedback_bot

Axolotls, also known as Ambystoma mexicanum, get their name from the Aztec language Nahuatl, meaning "water monster" or "water god." According to legend, they are the earthly form of Xolotl, the Aztec god who transformed into a salamander to avoid sacrifice. These creatures are famous for regenerating limbs, hearts, and even parts of their brains. They stay in their juvenile form for life, a trait called neoteny. In the wild, axolotls are critically endangered, with fewer than 1,000 left in Mexico’s Xochimilco and Chalco lakes. Habitat loss, pollution, and invasive species like tilapia are major threats. Conservation efforts are underway to restore their habitat and protect them from extinction. 🦎🌍💧 [Read more] If you have one as a pet, feel free to share with us! @googlefactss #Axolotl#WaterGod#EndangeredSpecies#Regeneration#Neoteny#Conservation#Wildlife#Mexico#Amphibians
