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

FALSE FLAG INCOMING: As Zionist officials claim #Hamas aka Palestinian Resistance were "carrying instructions on how to make chemical weapons " - @FoxNews interview son of "Hamas founder" Moses Hasan Yousef who was a spy for Zionist intelligence 1997 - 2007 before being given US residency. Yousef even betrayed his own father to Zionists. During Fox interview, Yousef recommends gassing Gaza tunnels to eliminate Hamas. He uses "we" which suggests he is still a traitor to Palestinian people & working with or for Zionists. Shin Bet considered him its most valuable source within the Hamas leadership. The information Yousef supplied exposed numerous Hamas cells, and assisted Israel in hunting down many militants, and incarcerating his own father, Hamas leader Sheikh Hassan Yousef. Yousef told Fox News' Brian Kilmeade that Israel should explore using gas after evacuating civilians in Gaza. "It sounds horrible, but I don’t see any other option. The tunnels are interconnected, and gas could be one of the solutions. But this has to be in the right time.." He recommends civilians are evacuated which means forced to leave their land for 3rd time to #Sinai. He then recommends using gas in tunnels to eliminate Resistance factions. However looking at the ridiculous claim Hamas + chemical weapons. What are the chances that a #WhiteHelmet style event will be orchestrated by Zionists - gassing civilians & blaming Hamas while exterminating more "human animals". Zionists know a ground invasion is suicide so this type of operation is viable alternative. Very high risk imo.

Israeli Ambassador to the United States, Yechiel Leiter, issued a threat to Egypt over the Egyptian army’s reinforcements in Sinai, labeling it a "serious threat" to the peace agreement with Tel Aviv. He revealed that the Israeli government will soon address the issue with greater urgency. Leiter accused #Cairo of building military bases "for offensive purposes," pointing to the addition of 700 tanks in the region as evidence of Egypt's growing military presence. He also criticized Egyptian President Abdel Fattah el-Sisi, claiming he is "playing both sides," but suggested that Sisi would be more open to cooperation with Israel if #Hamas in #Gaza is decisively dealt with. #EgyptIsraelTensions#Sinai#IsraelThreatensEgypt#MiddleEast#EgyptianArmy#Israel
