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}")

Politics, retribution behind FBI purge, agents allege in new lawsuit against Patel, Bondi
Three senior FBI officials who were abruptly fired last month by Kash Patel, the FBI director, are claiming in a new lawsuit against the Trump administration that they were illegally terminated at the direction of the White House for purely political reasons.
The complaint, filed in U.S. District Court in Washington, D.C., Wednesday, alleges Patel told one of the agents that his job as FBI director depended on firing agents involved in past investigations of President Trump.
Patel allegedly said "he had to fire the people his superiors told him to fire, because his ability to keep his own job depended on the removal of the agents who worked on cases involving the President," the lawsuit alleges.
"Patel explained that there was nothing [anyone] could do to stop these or any other firings, because 'the FBI tried to put the President in jail and he hasn't forgotten it,'" the complaint claims. According to the complaint, former FBI agent Brian Driscoll indicated he believed Patel was referring to his superiors at the White House and the Justice Department which "Patel did not deny."
