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

EVAA Protocol: Temporary Suspension of stTON in Main Pool #protocol#liquidity EVAA has temporarily suspended the use of stTON as collateral in its Main Pool due to reduced market liquidity. Existing positions remain unaffected, but users must repay active loans before withdrawing stTON. The measure is temporary and will be lifted once liquidity conditions improve. Source: link @tonlines

🚀 StarkWare Researcher Proposes Complex Bitcoin Transaction Scheme StarkWare researcher Avihu Mordechai Levy has introduced a Bitcoin transaction scheme that aims to circumvent the need for a protocol change. According to NS3.AI, the proposed method involves solving a pre-broadcast puzzle, which would necessitate approximately 70 trillion attempts. Levy characterized this design as a last-resort solution due to its significant computational demands, large transaction size, and potential relay-policy challenges, all of which could hinder scalability. #StarkWare#Bitcoin#transaction#AvihuMordechaiLevy#protocol#computationaldemands#scalability#relaypolicy#BTC

Ethereum Rollback Not Feasible, Developer Warns Ethereum developer Tim Beiko cautions against rolling back the Bybit attack, citing potential widespread disruptions and significant costs exceeding $1.5 billion. This attack does not breach Ethereum protocol rules unlike the 2016 TheDAO incident. Additionally, a Bybit address transferred $48 million to Galaxy Digital and FalconX, acquiring 34,800 ETH shortly before depositing it back into Bybit.

#java#bedrock#bedrock_edition#bedrock_to_java#bungee#fabric#geyser#geysermc#hacktoberfest#java#java_edition#minecraft#minecraft_bedrock_edition#packet#pe#protocol#proxy#spigot#translator#velocity Geyser is a free tool that lets you play Minecraft across different versions by connecting Minecraft Java Edition servers. It works by translating data between the two game versions, enabling cross-platform play on devices like Windows, iOS, Android, and consoles. You can install it as a plugin or standalone, and it supports recent Minecraft versions. This means you can join Java servers even if you only have Bedrock Edition, expanding your multiplayer options without needing a separate Java account if you use the Floodgate plugin. It’s great for seamless crossplay but may have some minor limitations due to game differences[1][2][5]. https://github.com/GeyserMC/Geyser
