我正在PyQt6中创建一个应用程序，为了防止窗口大小调整，我使用了该方法setFixedSize，但现在我需要允许这种更改。
怎么做？
主要.py
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("Main Window")
self.setFixedSize(645, 500)
def button(self):
# вот здесь мне надо изменить размер окна но у меня это не получается из-за метода setFixedSize

app = QApplication(sys.argv)
app.setStyleSheet(StyleSheet)
window = MainWindow()
window.show()
sys.exit(app.exec())
if __name__ == "__main__":
application_setup()
安装任何版本的 Unity 时，我都会收到错误“下载失败：验证失败”。我观看了很多文章和视频，尝试了所有方法，并以管理员身份运行 Unity 存档，下载了它，并更改了安装位置（我遇到了更多错误）在这种情况下我应该做什么？Windows 10 pro（现在是Windows 11 pro）上没有这样的问题

简而言之，我需要确保按下按钮时，所有小部件都被清除，包括背景（或者它更改为另一个小部件）并添加其他小部件。

我尝试在第一个文件中添加样式表，但没有任何效果
我在 PyQt5 中编写了一个应用程序，但后来我决定迁移到 PyQt6。我开始遇到错误，例如 PyQt6 没有我在 PyQt5 中使用的模块。我查阅了文档，解决了几个问题，但无法解决最后一个问题，即我将一个铭文放置在 QGridLayout 中并使用该方法将其固定在窗口的中心，但是在更新到 PyQt6setAlignment(Qt.AlignCenter)之后，我发现新版本中的Qt模块没有。我去搜索文档、互联网、YouTube、stackoverflow 以及任何可能的地方，并在文档中发现您应该使用 pyqtProperty，而不是 Qt 模块。我去将它导入到一个文件中，但它甚至没有为我导入！到底要做什么以及如何使用这个 pyqtProperty？这是代码：
from PyQt6.QtWidgets import QApplication, QLabel, \
QPushButton, QGridLayout, QWidget
from PyQt6.QtGui import QPixmap
from PyQt6.QtCore import pyqtProperty # вот это атрибут(метод) я хотел импортировать, но у меня не получилось
import sys
class QuizApplication(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Quiz")
self.setGeometry(600, 100, 648, 500)
self.pixmap = QPixmap("background_image.jpg")
self.background_label = QLabel(self)
self.background_label.setObjectName("background_label")
# self.background_label.setAlignment(Qt.AlignCenter) вот это метод я использовал в PyQt5
self.background_label.pyqtProperty()
self.background_label.setPixmap(self.pixmap)
self.background_label.adjustSize()
self.welcome_label = QLabel(self)
self.welcome_label.move(200, 0)
self.welcome_label.setObjectName("welcome_label")
# self.welcome_label.setAlignment(Qt.AlignCenter)
self.welcome_label.setWordWrap(False)
self.welcome_label.setText(
"Это будет викторина по истории, философии и обществознанию.")
self.welcome_label.adjustSize()
self.start_button = QPushButton(self)
self.start_button.move(100, 480)
self.start_button.setObjectName("start_button")
self.start_button.setText("Нажмите чтобы начать!")
self.start_button.adjustSize()
self.grid = QGridLayout()
self.grid.addWidget(self.welcome_label)

我正在PyQt5中制作测验应用程序。我添加了文本、按钮和背景图像，但下一个问题是如何使窗口响应？
我在 RuNet、英语互联网和 YouTube 上进行了很多谷歌搜索，但我没有找到任何东西。

我开始学习PyQt5，但是我无法制作主窗口。这是代码：
import sys
from PyQt5.QtWidgets import QApplication, QWidget
class App_PyQt(QApplication):
def __init__(self):
self.app = QApplication(sys.argv())
self.w = QWidget()
self.w.resize(300, 300)
self.w.move(300, 500)
self.w.setWindowTitle("Example")
self.w.show()
sys.exit(self.app.exec_())
Main_Window = App_PyQt()
