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

Cholesterol protects the integrity of cell membranes and keeps cells healthy and strong. If a person’s cholesterol level were 0 (an impossibility), his cell membranes would be dry and cracked and all the cell content would leak out. @googlefactss#humanbody

The same skin cells that make up a human vagina are the same type of cells that are in a human mouth. The nonkeratinized stratified squamous epithelium are types of mucous membranes that are sensitive, absorbent, and continuously shed and regenerated. @googlefactss#humanbody

Occasionally, human corpses can undergo saponification, a process in which body fat transforms into adipocere through a chemical reaction. Adipocere has a consistency similar to semi-hard cheese and possesses a soapy feel. The most well-known example of this phenomenon is the "Soap Lady," a 140-year-old mummy showcased in Pennsylvania. @googlefactss#humanbody#nowyouknow

Myth: The tongue is divided up into specific areas that are solely responsible for sensing certain tastes (e.g., sweet at the tip, bitter at the back) Fact: The tongue's receptor cells that identify the molecules underlying the basic tastes (sweet, sour, salt, bitter and umami) are distributed on taste buds all over the tongue although some areas may be slightly more sensitive to certain flavors.. @googlefactss#humanbody#nowyouknow#mythbusted [read more...]

Fingernail facts: The middle finger’s nail grows the fastest while the smallest finger’s grows the slowest. Nails usually grow faster on your dominant or more active hand (more use → more repair → more blood/nutrients) and speed up in summer thanks to better circulation. Toenails grow slower. Overall, males’ nails often grow faster than females’, but during puberty and pregnancy higher hormone levels make nails grow quicker in women. [Source] @googlefactss #FunFact#HumanBody#nails
