Question

下面附有截图：
所以基本上我想把文件作为输入（即suffix_list.txt）而不是在函数内指定文件位置，当我点击动作按钮时我需要在QtTextEdit中执行输出
我尝试了一些东西，但我无法得到它。请帮帮我。我是PyQt5的新手。谢谢你这是我的gui代码：

Answer 1

您遇到的两个主要问题是，如果需要file_open的实例，则不要调用Ui_MainWindow方法并在文件对话框中提供MainWindow的实例。 }。以下是解决此问题的方法：

def retranslateUi(self, MainWindow):
    self.main_window = MainWindow
    # your code here
    self.actionOpen_File.triggered.connect(self.file_open)

def file_open(self):
    name, _ = QtWidgets.QFileDialog(self.main_window, 'Open File', options=QtWidgets.QFileDialog.DontUseNativeDialog)
    # your code here

但是，在您的代码结构中，此问题的范围之外存在一些问题，这将导致难以扩展。
