from telegram import Update
from telegram.ext import ApplicationBuilder, CommandHandler, ContextTypes
import asyncio
import sys

async def start(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None:
    await update.message.reply_text("Hi.")

async def run_bot(token: str) -> None:
    app = ApplicationBuilder().token(token).build()
    
    app.add_handler(CommandHandler("start", start))
    
    print("Бот запущен...")
    await app.run_polling()

if __name__ == "__main__":
    token = 'mytoken' 

    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop) 

    try:
        loop.run_until_complete(run_bot(token)) 
    except KeyboardInterrupt:
        print("Бот остановлен.")
        sys.exit(0)
    except Exception as e:
        print(f"Произошла ошибка: {e}")
    finally:
        loop.close()

关键是当我删除这段代码时它可以工作async run_bot，但为什么不能把所有东西都放进去呢async？

为什么这件事做不到或者我什么都没做？

我希望距离与绘制棍子的地方的十字位置相同。
当我添加第一个小部件时，它出现在最顶部，正如您在屏幕截图中看到的那样，但是当我添加第二个小部件时，它出现在中间，其中显示大约 4-5 个小部件。

我希望它们在第一个之后立即添加，也就是说，它们没有很大的距离。

这是这段代码，我希望小部件之间的距离与最顶部（我放置十字的位置）相同，此外，我需要在第一个小部件之后立即创建小部件

我不明白为什么这些样式不起作用？请详细解释一下，我刚刚开始学习PyQt6库。

我有这段代码，我想SubWidget()对其应用样式，但是当我setstylesheet直接使用它时，它不起作用。
此外，和SubWidget()并未突出显示，尽管它们在代码中起作用。 我究竟做错了什么？.addWidgetremoveWidget
