PySide6文本框拖拽事件的问题

小朋友呢

1.如果所示，在向TextEdit拖入文件并读取内容后，它的光标，就不闪了，一直定在这


2.下面是我的处理拖拽事件的代码，试过网上很多的激活跟设置焦点的方法，但它的光标就是定住的状态，求助一下各位大佬如何解决

  def dragEnterEvent(self, event):
      if event.mimeData().hasUrls():
          event.accept()             
      else:
          event.ignore()
      event.acceptProposedAction()
      

  def dropEvent(self, event):        
      for url in event.mimeData().urls():            
          file_path = url.toLocalFile()
          content = get_file_content(file_path)
          self.ui.plainTextEdit_cert.setPlainText(content)
          self.ui.plainTextEdit_cert.setFocus()
      event.acceptProposedAction()

在你重写的dropEvent事件内先执行父类的dropEvent，比如super().dropEvent(event)，很久没写Python了忘得差别不多了不知道有没有写对，如果不是dropEvent的问题再看看dragEnterEvent

大佬，我试了一下用super，因为我是自定义类，不是控件类，发现还是不行，后来我就保存了原来的dropEvent事件，调用自己的dropEvent事件的时候，就调用一下原来的dropEvent就可以了

    self.save_dropEvent = self.ui.plainTextEdit_cert.dropEvent
    self.ui.plainTextEdit_cert.dropEvent = self.dropEvent

我没仔细看，我还以为你的类是继承自QPlainTextEdit然后重写dropEvent呢
