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

International Court of Justice (#ICJ ) has finally had enough of #Israelis and their #genocidal actions against the #Palestinians of Gaza It has finally decided to do what #SouthAfrica demanded it should have done months ago: • Demand that the #ZioNazis halt their #genocidal slaughter of innocents in #Gaza and that • Israel must ensure access to Gaza for UN genocide investigators

UN rapporteur: Israel will not stop ‘this madness’ until we make it stop Francesca #Albanese, the #UN’s special #rapporteur on #Palestine on Saturday urged member states to impose sanctions on #Israel along with an arms embargo until it stops “this madness,” “Let’s be clear. As the #ICJ orders Israel to stop its offensive in #Rafah, #Israel instead intensifies its attacks on it,” The International Court of Justice (#ICJ) in its latest ruling ordered Israel to immediately halt its military offensive in #Rafah, a city in southern Gaza where more than 1.5 million displaced Palestinians had sought refuge. “The news I am receiving from the people trapped therein are terrifying, Be sure: Israel will not stop this madness until WE make it stop,” Albanese urged all UN member states to impose #sanctions, arms #embargo and suspend diplomatic and political relations with Israel until it ceases its #genocidal assault.

A legal group submitted to the #UN the most thorough legal analysis of Israel's actions concluding it is committing genocide against Palestinians in Gaza. This is probably the most complete report to date that demonstrates how #Israel's attacks on #Palestinians in #Gaza meet the legal definition of #genocide. It's a 100-page report, by legal experts at #Boston University School of Law, #Cornell Law School, #Yale Law School, and others. The report's conclusion: "Israel has committed the #genocidal acts of #killing, causing serious harm to, and inflicting conditions of life calculated to bring about the physical #destruction of #Palestinians in #Gaza, a protected group that forms a substantial part of the Palestinian people. These #genocidal acts have been motivated by the requisite genocidal intent, as evidenced in this report by the statements of #Israeli leaders, the character of the State and its forces’ conduct against and relating to Palestinians in Gaza, and the direct nexus between them."
