我想在我流畅的 Ui 上创建一个启动屏幕，但在这个 Ui 窗口中标题栏的按钮在那里。我不想要这个。我是初学者，所以请帮助我。我尝试修复此代码，但失败了，所以请告诉我如何修复它。当我运行此代码时，窗口成功打开，但图标可见。没有任何错误，请告诉我如何修复它

进行以下更改将显示 3 秒的启动屏幕。
添加QTimer如下，在InitUi中如下图：
from PyQt5.QtCore import Qt, QSize, QEventLoop, QTimer
删除对 initwindow() 和 createSubInterface 的调用，添加 新的 close_screen 方法，并设置 resize() 和 QSize() 尺寸为“700、600”均如下所示：
class Mainwindow(QMainWindow):
def __init__(self):
super().__init__()
# self.initwindow()
self.initUi()
self.window()
def close_screen(self):
self.splashScreen.close()
def initUi(self):
self.resize(700, 600)
self.setWindowTitle('WhatsApp')
self.setWindowIcon(QIcon('<your splash image>'))
self.splashScreen = SplashScreen(self.windowIcon(), self)
self.splashScreen.setIconSize(QSize(700, 600))
QTimer.singleShot(3000, self.close_screen) # close splash screen after 3 seconds
# create other subinterfaces
# self.createSubInterface()
