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

She was totally surprised that I’d “let her go” after she admitted the cheating. She had expected a long intensive fight. But I did not want her back. In fact never, ever. She had turned into a liar — someone who had lied for months and months, each and every day. The irony is: the literal second before she told me the truth (which I had suspected for almost six months, but which she had virgorously denied), I would have done anything for her. I had fought for many months over a period which felt like one long nightmarish night with everything I got, but as soon as the truth — and nothing but the truth — was out, the fight was over. She was a liar. Had become one. Would always be one. So I did not fight anymore. That is to say: not for her. That had become a war I could not win anymore, and one she had already lost. So she was gone forever, and I realized I had to start all over again, trying to walk to new horizons and not knowing what to expect. After 10 fucking years. The nights became cold, and silent. And she smelled blood, smelled my weakness, so she went for the kill, for the money, for the house, thinking that now I was lying in my own pool of stinking tears, she might as well bash in my head and get it over with. She announced it to her friends, to her family. She would get the money. She would ruin me — she was a new person now, and would not care about her old life, ever again. (Her words.) And, dear friend, I will end my little sermon now with my own three beautiful words. She lost again. #review #breakup #auri
