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}")

Explainer from #Addis_Standard Newsroom:
As of 24 February, Addis Standard has not received any formal written notice, legally mandated opportunity to respond, or reasoned decision preceding the #Ethiopian Media Authority’s public claim, made via social media, that our online media registration was revoked.
Ethiopian media law is clear: suspension or revocation of a media license must follow a defined process, including written notice, a 14-working-day right of response, a reasoned decision, and access to appeal before the Authority’s Board of Directors.
None of these mandatory steps have been observed. Addis Standard remains fully operational and continues its public-interest journalism in good faith, while its publisher, #JAKENN Publishing PLC, pursues clarification and rectification through lawful channels. This matter goes beyond one newsroom, it concerns whether media regulation in Ethiopia is governed by law, due process, and institutional accountability.

News: Publisher challenges #EMA’s revocation of Addis Standard registration, cites due process violations
#JAKENN Publishing P.L.C., the publisher of #Addis_Standard, has formally contested the decision by the #Ethiopian Media Authority (EMA) to revoke the outlet’s online media registration certificate, arguing that the move lacks legal basis and violates due process guarantees under Ethiopian law.
The response follows an announcement circulated on the Authority’s official social media channels on 24 February 2026, stating that Addis Standard’s registration had been revoked.
In a letter addressed to the EMA Board of Directors, JAKENN said a legal review found the announcement “exceeds the Authority’s procedural powers” and is incompatible with safeguards provided under Media Proclamation No. 1238/2021, as amended by Proclamation No. 1374/2025.
The publisher stressed that Addis Standard is operated by JAKENN Publishing P.L.C., a legally registered private....

News: #Ethiopian Media Authority revokes Addis Standard’s online media registration; Editor-in-Chief disputes claims
The Ethiopian Media Authority (#EMA) has announced the revocation of the online media registration certificate of #Addis_Standard, effective 24 February 2026, citing repeated violations of media ethics, national laws, and what it described as the country’s national interests.
The statement did not specify which reports or actions formed the basis of the decision.
Responding to the EMA’s announcement, Yonas Kedir, Editor-in-Chief of Addis Standard publications, rejected the Authority’s claims, saying the outlet had never received any formal notices of violations.
“The claim that Addis Standard received repeated notices is factually incorrect. At no point has the Ethiopian Media Authority formally notified Addis Standard newsroom of any prior violations or enforcement actions,” he said. He added that the publisher, #JAKENN Publishing PLC, ..…
