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}") #tricks#qt

California announces plan to charge landowners for their own water It's not satire — it's Agenda 2030 perfect awareness of all resources and economic activity. California has announced to landowners that they now are going to be billed for the water they take out of their own wells, on their own land. Hundreds of dollars in fees are looming, with 25% penalties for those who don't pay on time: "Landowners whose property is within an unmanaged area and contains an operating ground water extraction well must report the volume of groundwater extracted from the well. The groundwater extraction volume must be reported as a monthly total. In addition to pumping volumes, reports must include the location of the well and the place and purpose of use of the groundwater. Groundwater extraction reports are not due to the state water board until February 1, 2023. However, if you are required to report, the report must include pumping volumes for each month between the date of receipt of this letter and September 30, 2022." #Water https://www.wnd.com/2022/07/california-announces-plan-charge-landowners-water/

A water filter called "Life Straw" allows a person to drink directly from a dirty water source. Extremely portable and easy to use, it filters water through pores that are tiny enough to block parasites and other types of bacteria. [Read more..] @googlefactss#water#nowyouknow

🌎 In Mexico's Yucatán Peninsula, the cenote Ik Kil is a natural sinkhole filled with crystal-clear water, formed by collapsed limestone over thousands of years. Once sacred to the Maya, these cenotes provided fresh water and served as entrances to the underworld in ancient beliefs. ✨ #geology⚡#history⚡#water 👉subscribe Interesting Planet
