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

CVMA Student Wins Top Prize in Human Rights Essay Competition December 10, 2025 – Addis Ababa, Ethiopia In celebration of International Human Rights Day 2025, the Center for Human Rights, in collaboration with the UN Human Rights Office (OHCHR), has announced the winners of its essay competition titled “Our Everyday Essentials: Reclaiming Human Rights in the 21st Century.” We are proud to announce that Yared Ermiyas, a student from the College of Veterinary Medicine and Agriculture at Addis Ababa University, emerged as the first-place winner. His powerful essay, “Remove the Shadow,” eloquently argued that access to education must be a fundamental necessity for every child, not a matter of luck, highlighting the deep emotional and practical connection between education and a dignified life. Yared was awarded a mobile phone prize presented by H.E. Berhanu Adello, Chief Commissioner of the Ethiopian Human Rights Commission (EHRC). Commissioner Adello also extended an offer for Yared to begin an internship attachment at the National Bureau of the Human Rights Commission, providing a valuable opportunity for practical experience in the field. The awards ceremony featured a dynamic panel discussion where Yared and the other winners presented their essays and engaged with fellow students and audience members on critical issues related to freedom of expression and the right to education. The competition, which invited undergraduate students to reflect on the core human rights that shape our daily lives, successfully inspired thoughtful dialogue and showcased the intellectual talent within our university community. Congratulations to Yared Ermiyas and all the participants for raising your voices, sharing your vision, and helping to shape the future of human rights!
