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}")

🇨🇲#Cameroon: ISWAP militants have attempted to storm a new position of The Rapid Intervention Battalion (Bataillon d'intervention rapide - BIR, a special forces unit of the Cameroonian Armed Forces) in the town of Bargaram, near the Nigerian border.
At least five militants were killed in the failed attack, including one who was reportedly a foreigner. Footage shows the equipment that the BIR captured from the dead militants, including a camera which was supposed to be used in order to film the attack as further propaganda.

#UK to end study visas for #Sudan, #Cameroon, Myanmar, Afghanistan students
The United Kingdom says it will end study visas for students from #Afghanistan, Cameroon, #Myanmar and Sudan, and work visas for Afghans, amid a rise in anti-immigration sentiment in the country.
The UK Home Office said in a statement on Tuesday that “an ’emergency brake’ on visas has been imposed for the first time on nationals from four countries”, following a surge in asylum claims by students on study visas.
The Home Office said the number of asylum applications by students from Afghanistan, Cameroon, Myanmar and Sudan had “rocketed” by more than 470 percent between 2021 and 2025.
“Britain will always provide refuge to people fleeing war and persecution, but our visa system must not be abused,” Secretary of State for the Home Department Shabana Mahmood said.
“That is why I am taking the unprecedented......
