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

🌿 March 3 – World Wildlife Day 🌿 Today we celebrate World Wildlife Day, raising awareness about the importance of protecting wildlife and preserving biodiversity. 🌏 On December 20, 2013, the United Nations officially declared March 3 as World Wildlife Day. This year also marks the 40th anniversary of the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Wildlife has ecological, genetic, social, economic, scientific, cultural, and aesthetic value. That’s why people often seek the peace of wild nature away from noisy cities. 🌲🦉 Our great scholars emphasized respecting nature and maintaining balance: Muḥammad Muso Khorezmi: “Know that if the eyes of the river weep, sorrow will fall upon it.” Abu Nasr Farabi: insights on human body, nutrition, and diseases. Abu Rayhan Beruni: studies on plants and animals, their biological traits and economic importance. Avicenna (Ibn Sina): advice on health, hygiene, diet, and natural remedies. ❗️ Human impact on wildlife: 1️⃣ Deforestation and habitat loss – ~10 million hectares of forest are lost globally each year. 2️⃣ Extinction of species – over 1 million animal and plant species are at risk. 3️⃣ Air, water, and soil pollution – over 50% of coral reefs degraded; 75% of the Earth’s land affected by climate change and human activity. 4️⃣ Illegal wildlife hunting and trade – threatens more than 2,200 species. Each of us is responsible for protecting nature, avoiding pollution, and passing it on intact to future generations! 💚🌿 #WorldWildlifeDay#ProtectNature#Biodiversity#WildlifeConservation#EcoAwareness
