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

Every day people from all parts of the world would remind me how amazing their lives are and how mine isn't. I notice most of the people around me are just pretending to be happy, they show me what they want me to see not what i'm needed to see. I somehow know the truth but it's just so tough to believe it. It's just that my heart is so used to being sad about every other single situation, now it finds it challenging to become something it has never been. Honestly, my heart gave up on me a long time ago because my dumbass would always try to find reasons to make myself feel like shit. With time I reached a point where I no more cared if I was happy or not.I had no idea about what I was trying to do with myself. I didn't care if I watched that tv show which I used to enjoy, I didn't care if I ate those chicken rolls that my mom prepared just for me because I would beg her to make them, I didn't care if I was healthy, I didn't care about my looks, desires, likes, dislikes. I reached a point where I had no more fucks left with me to give to the world or to myself. During one of the summer holidays my best friend who came to visit me after two whole years would scan my whole appearance with a concerned disgust in his eyes. "Well, you look like shit. I heard from your mom that you haven't eaten anything since last two days. Are you trying to kill yourself or some shit? " I smiled because I finally figured out what I was trying to do with myself. "Hopefully" #review#J # #promptWriting (English isn't my first language, I need constructive criticism 😭)
