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}")

🖌📕Make the most of your Writing test:
@ieltsstrategies
• analyse each task properly and spend some time making notes
• highlight or underline key words in the tasks to make sure that you focus on what you have to do
• plan your answers
• use paragraphs clearly; put one idea in each paragraph
• do not repeat ideas using different words
• do not copy whole sentences from the question – you will receive no marks for this
• keep to the topic; do not write about unrelated subjects
• manage your time; remember, Task 2 is worth twice as much as Task 1
• spend approximately 20 minutes on Task 1 and approximately 40 minutes on Task 2
• you must write your answers in full; answers written in note form or in bullet points will lose marks
@ieltsstrategies
• pay attention to spelling, grammar and punctuation; you will lose marks for mistakes
• avoid informal language
• do not memorise model answers; examiners are trained to recognise them and your test will be invalid
• spend several minutes re-reading and correcting your answers
