从tkin中的file1按下按钮时如何跳转运行/执行file2

Question

我有2python文件文件1&；文件2用tkinter编码

文件1是Welcome page，有一个作为医生登录的按钮

文件2是医生将在其中输入其凭证的login page。 两个文件都用tkinter编码

Running:-

1. 欢迎文件（文件1）将以GUI形式运行
2. 当按下文件1上的按钮时，它应该被重定向到 登录页面（文件2）

Note:-

两个文件都不同

File 1 Welcome.py

按下欢迎页面的按钮登录页面应以gui形式执行

请帮助我有一个大学小项目，但我被困在这里了……

Answer 1

1. 这绝对不是从主窗口打开第二个窗口的正确方法。在Tkinter中，如果您需要添加窗口，我们使用Toplevel()，而不是使用另一个Tk()，尽管它可以工作，但不是推荐的方法

2. 这里不需要importlib，不用它就可以很容易地完成

   就像您可以在file.py中定义一个函数一样，在主文件中import file，然后按文件1中的按钮file.Run_login调用它

   示例：

   文件2

   def Run_Login():
       # creating the object
       root = Toplevel()
   
       # resolution of the window
       root.geometry("1520x790+0+0")
       root.title ("ABC HOSPITAL")
       # root.iconbitmap('hospital.ico')
   
       # preventing the resize feature
       root.resizable(False, False)
       Application(root)
   

   文件2：

   import file
   
   def doc():
       file.Run_Login(master=root)
   

3. 同样，在应用程序类中继承Toplevel将使您的工作更轻松，因为这样您就可以将类导入文件1from file import Application。在医生那里你可以叫它

   示例：

   def doc():
       A = Application(master = root)
