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

Был бы у меня такой кот, я, может, и не женился бы никогда.

Did you know that Spanish 🇪🇸 uses upside down exclamation and question marks (¡ and ¿) at the beginning of sentences? ¡Qué bonito! ("How beautiful!") ¿Cómo estás? ("How are you?") Creo que tienes razón, pero ¿estás completamente seguro? ("I think you're right, but are you completely sure?") Below you'll find a block of questions on these upside down punctuation marks. For each question react with 👍🏻 if you got it right and 🙈 if you got it wrong. @languagetrivia#question_block#punctuation

In the world of printing and journalism, the exclamation mark (!) has earned a variety of colorful nicknames. One of these humorous terms compares its shape to a specific part of a dog’s anatomy. Sometimes an exclamation mark is humorously referred to as “a dog’s [what]"? A) Tail 🐕 B) Nose 👃 C) Bone 🦴 D) C*ck🍆 Take the quiz below to find out @languagetrivia#punctuation#symbol#slang

✏️Did you know about the Oxford comma, also known as the serial comma? It's the final comma in a list of three or more items, placed before "and" or "or." For example: 🔵I invited my parents, Taylor Swift, and Elon Musk. Without the Oxford comma, it could look like this: 🔵I invited my parents, Taylor Swift and Elon Musk. Wait, are my parents Taylor Swift and Elon Musk?! 😅 Not everyone agrees on its usage: 🟢Proponents argue it provides clarity and prevents ambiguity 📝 🟣Opponents feel it’s unnecessary in straightforward cases and takes up space 📰 For instance, the AP Stylebook often skips it unless absolutely needed, but the Chicago Manual of Style recommends using it in all cases. Here are some examples showing how the Oxford comma can help fight ambiguity: 1️⃣Avoiding Misinterpretation: I dedicate this book to my parents, Mother Teresa, and the pope. Without the Oxford comma: I dedicate this book to my parents, Mother Teresa and the pope. This could imply that your parents are Mother Teresa and the pope. 😳 2️⃣Clarifying Groupings: We had coffee, cheese and crackers, and grapes. Without the Oxford comma: We had coffee, cheese and crackers and grapes. This could suggest that "crackers and grapes" are a combined dish. 🍇🧀 3️⃣Costly Consequences: O'Connor v. Oakhurst Dairy (2017) was a U.S. legal case where truck drivers sued for overtime pay, challenging an ambiguous Maine law that lacked an Oxford comma. The law exempted work involving "packing for shipment or distribution" of goods. Without a comma, it was unclear if "distribution" was part of "packing" or a separate activity. The court sided with the drivers, interpreting the ambiguity in their favor, leading to a $5 million payout. 💸 📌Ultimately, whether or not you use the Oxford comma is up to you, but the key is to be consistent. And it's also a good idea to use it in cases where it can help prevent ambiguity and misinterpretation!
