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}")

The sunrays taking;
All the darkness away,
Love taking all hatred away,
Miniature hopes in shapes of stars,
Now subsiding in beautiful destiny,
Happiness taking all the pain away.
In midst the beautiful world,
I laid here,
Breathless,
My sould taken away by you,
My heart given to beat in someones
Else's cage,
My body drifted with fire,
My voice taken away by deafening silence,
My memories now, washed away,
Fading away with new ones.
This is how,
A beautiful day began,
Changing my life,
To be dreadful forever,
In midst the beautiful world,
I laid here as a dead lover.

She's like a poem,
Waiting to be read.
She's like a song,
Waiting to be sung.
She's like a melody,
Waiting to be heard.
She's like a book,
Waiting to be understood.
She's like a dance,
Waiting to be performed.
She's like a beauty,
Waiting to be cherished.
She's like art,
Waiting to be crafted.
She's you,
Waiting to be found.
She's you,
Waiting to be loved.
She's not just a girl,
She's within all of you,
She resides somewhere inside,
Somewhere the golden rays don't reach,
Somewhere the silver shine doesn't work,
Somewhere in you,
She stays,
Waiting to be acknowledged.

During a dreadful night,
I managed to put up a fight.
Maybe the strong me died,
And weak me survived.
The constant voices in my ears,
Here I am living in my fears.
Like a painful reminder of that night,
Where I lost a outnumbered fight.
Wondering if I am even right,
While holding myself tight.
The night is long dead,
Here my tears still wetting my bed.
That dreadful night,
The cause of my fright.
These thoughts make me shiver,
The fear making me quiver.
My painful screams,
Still haunting my dreams.
Maybe the strong in me died,
And weak me survived.
I haven't given up the fight,
Because I know,
I can still make it right.
