Установить свойства виджета в PySide можно не только через соответствующие методы и конструктор класса. Можно их изменять с помощью метода setProperty по имени. btn = QPushButton("Click Me") btn.setProperty("flat", True) Это аналогично вызову btn.setFlat(True) Если указать несуществующее свойство, то оно просто создается btn.setProperty("btnType", "super") Получить его значение можно методом .property(name) btn_type = btn.property("btnType") Когда это может быть полезно? ▫️Можно просто хранить какие то данные в виджете и потом их доставать обратно widget = QWidget() widget.setProperty('my_data', 123) print(widget.property('my_data')) ▫️ Назначая эти свойства разным виджетам можно потом отличить виджеты во время итераци по ним. Например, найти все кнопки со свойством my_data="superbtn". Но ведь вместо кастомного свойства можно использовать objectName, будет тот же результат. Да, но y ObjectName есть ограничение - только строки. ▫️ Если нам потребуется не просто поиск а, например, сортировка по числу, то свойства позволяют нам это сделать. Поддерживается любой тип данных widget.setProperty('my_data', {'Key': 'value'}) widget.setProperty('order', 1) all_widgets.sort(key=w: w.property('order')) Но ведь Python позволяет всё вышеперечисленное сделать простым созданием атрибута у объекта widget.order = 1 widget.my_data = 123 Да, но я думаю что не надо объяснять почему не стоит так делать. К тому же, если у виджета нет свойства то метод .property(name) вернет None, а отсутствующий атрибут выбросит исключение. ▫️ Действительно полезное применение кастомным свойствам - контроль стилей. Здесь атрибутами не обойтись, нужны именно свойства. Дело в том, что в селекторах стилей можно указывать конкретные свойства виджетов на которые следует назначать стиль. Просто запустите этот код from PySide2.QtWidgets import * if __name__ == "__main__": app = QApplication([]) widget = QWidget(minimumWidth=300) layout = QVBoxLayout(widget) btn1 = QPushButton("Action 1") btn2 = QPushButton("Action 2") btn3 = QPushButton("Action 3", flat=True) layout.addWidget(btn1) layout.addWidget(btn2) layout.addWidget(btn3) # добавим кастомное свойство одной кнопке btn1.setProperty("btnType", "super") # добавляем стили widget.setStyleSheet( """ QPushButton[btnType="super"] { background-color: yellow; color: red; } QPushButton[flat="true"] { color: yellow; } """ ) widget.show() app.exec_() С помощью селектора мы избирательно назначили стили на конкретные кнопки. Как получить список всех кастомный свойств? Функция получения списка кастомных свойств отличается от получения дефолтных. def print_widget_dyn_properties(widget): for prop_name in widget.dynamicPropertyNames(): property_name = prop_name.data().decode() property_value = widget.property(property_name) print(f"{property_name}: {property_value}") #tricks#qt

News: Fuel shortages deepen in #Addis_Abeba, regional cities as drivers endure prolonged queues Drivers in Addis Abeba and several regional cities report worsening fuel shortages, with prolonged queues and dwindling supplies deepening the strain caused by recent price hikes. At present, beyond rising costs, fuel is reportedly becoming increasingly scarce in cities including #Mekelle, #Jimma, #Ambo and #Bahir_Dar. Drivers who spoke to Addis Standard described spending hours in queues at fuel stations, often with no guarantee of securing supply. A public transport driver in Mekelle said the situation has deteriorated sharply. “Beyond the price hike, it feels like fuel is heading toward complete disappearance. We are buying a 20-litre jerrycan for 8,000 birr, and that too after waiting in line for more than five hours,” he said. Read more: https://addisstandard.com/?p=55586

#In_Depth_Analysis: The #Hormuz Entanglement: Why #Ethiopia’s fuel crisis is a perfect storm of #war, #graft, and #reform While the immediate catalyst appears to be the high-stakes military escalation between the U.S., Israel, and Iran, a deeper look reveals that Ethiopia’s fuel misery is a complex entanglement. It is a “perfect storm” where geopolitical vulnerability, a domestic system rotting from within, and a painful macroeconomic experiment have collided to leave 120 million people running on empty. Until the govt can clean its own house, root out the “senior decision-makers” profiting from the black market, and navigate the treacherous waters of Middle Eastern diplomacy, the accounts emerging from #Gonder to #Jimma to #Ambo, and from #Hawassa to #Bishoftu and #Mekelle, point to an Ethiopia that will remain running on empty. It will be a country “stalled at the intersection of a distant war it cannot control and a local crisis of governance it has yet to master”... https://addisstandard.com/?p=56099
