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}")

Banking & telecom will potentially spend ₹2,000 cr over 5 years to become #quantum ready. A Feb 2026 roadmap calls for phased adoption of post-quantum cryptography, prioritising critical sectors & targeting nationwide rollout by 2033.
For PSBs, this means auditing existing encryption, mapping exposed systems & piloting PQC post-quantum or hybrid schemes. Since encryption is deeply embedded across apps, payment rails, ATMs, cloud & data centers, the transition will be gradual & costly but the only counter to Harvest Now, Decrypt Later attacks.

Solana Unveils Quantum-Resistant Vault
Solana developers introduce the *Solana Winternitz Vault*, a quantum-resistant solution using a hash-based signature system that generates unique keys for every transaction. Currently, it's an optional feature rather than a mandatory network upgrade. More details: Decrypt

🌎 Researchers use particle accelerators like the Large Hadron Collider to search for evidence of extra dimensions tied to parallel worlds. These experiments look for missing energy or unusual particle behavior that might reveal hidden spatial dimensions. No direct evidence has been found, but data continues to challenge and refine our understanding of reality’s structure. ✨

🌎 Scientists exploring the mysteries of parallel worlds suggest that, according to quantum mechanics, alternate dimensions could exist alongside our own—each with its unique version of reality. Though unproven, this idea helps explain puzzling phenomena in physics and inspires everything from science fiction to cutting-edge research about the nature of our universe. ✨
