Question

我是Python新手，刚刚开始尝试使用GUI。我创建了一个非常基本的Tkinter窗口：它有3个Entry栏和3个File Dialog按钮。当您选择第3个目录时，GUI文件会自动调用单独的文件并接收一个大文本块，然后在文本框中显示。

整个过程正常，但我的问题是，在接收并插入文本响应后，Tkinter停止工作，并且不允许用户向下滚动。

我读到发生这种情况的一个原因是人们同时使用.pack( )和.grid( )，但我并没有将这两个功能混合在一起。

提前感谢您的帮助！

这是我的GUI文件

# Start the GUI
root = Tk( )
root.title("Python gpsExtractor")
root.geometry("650x650")
app = Application(root)
root.mainloop( )

文本插入后Tkinter窗口无响应
