如何在python中的GUI或窗体中调用新的GUI或窗体？

我正在尝试使用python中的套接字编程创建一个简单的聊天服务器。我正在使用Tkinter构建GUI。这是我的问题，我有一个login.py文件，它让我看到了登录的形式。然后我有这个signup.py。现在，当我单击“注册”按钮时，我想从登录表单导航到注册表单。请帮忙！这是我的示例代码。只是为了导航

login.py

from Tkinter import *
import Signup

class Login():
    def __init__(self):
        self.root = Tk()
        self.root.title("Welcome to Login")
        self.btnSignup = Button(self.root, text="Not a member? Sign up now!", relief=FLAT,
                                borderwidth=1, font=("Century Gothic",11,'normal'),
                                command = self.callSignup, fg="white",bg="#0866c6", 
                                activebackground="#404040",activeforeground="white")
        self.btnSignup.place(width = 250, height = 25, x = 10, y = 10)
        self.root.mainloop()

    def callSignup(self):
        self.root.destroy()
        self.obj = Signup.signup("james")
        self.obj.display()

from Tkinter import *

class signup():
    def __init__(self,name):
        self.name = name

    def display(self):
        self.root = Tk()
        self.root.title("Welcome " + self.name)            
        self.root.mainloop()

signup.py

from Tkinter import *
import Signup

class Login():
    def __init__(self):
        self.root = Tk()
        self.root.title("Welcome to Login")
        self.btnSignup = Button(self.root, text="Not a member? Sign up now!", relief=FLAT,
                                borderwidth=1, font=("Century Gothic",11,'normal'),
                                command = self.callSignup, fg="white",bg="#0866c6", 
                                activebackground="#404040",activeforeground="white")
        self.btnSignup.place(width = 250, height = 25, x = 10, y = 10)
        self.root.mainloop()

    def callSignup(self):
        self.root.destroy()
        self.obj = Signup.signup("james")
        self.obj.display()

from Tkinter import *

class signup():
    def __init__(self,name):
        self.name = name

    def display(self):
        self.root = Tk()
        self.root.title("Welcome " + self.name)            
        self.root.mainloop()

当我运行代码时，我可以打开注册表单。但是self.root.destroy（）在登录时，py不起作用！请帮帮我！谢谢

我将使用两种方法解决您的问题

因此，基本上，您正在寻找：

• 用户单击“注册”按钮：

• 单击必须提示一个注册窗口：

第一种方法： 第一种方法建议重新设计您的应用程序：我的意思是，为了完成此任务（实际上），最好将窗口集中在同一个模块中，而不是两个单独的

login.py

和

signup.py

模块。我更倾向于从方法开始，因为它有第二个优点，可以简单地解决您的问题。让我们调用我们的模块

loginsignup.py

在类的构造函数中，在构造函数中设置框架小部件：

def __init__(self, parent):
        Tkinter.Frame.__init__(self, parent)
        self.parent = parent

为了更好的设计，最好在单独的函数中分离GUI设计，例如，

initialize\u membership\u interface（）

。当然，必须在上面的构造函数主体中调用此方法：

def __init__(self, parent):
        Tkinter.Frame.__init__(self, parent)
        self.parent = parent
        self.initialize_membership_interface()

初始化成员资格接口（）

实例化2个按钮和一个标签。使用该方法在框架内组织这3个小部件：

def initialize_membership_interface(self):
        self.parent.title('Membership Area')
        self.parent.grid_rowconfigure(0, weight = 1)
        self.parent.grid_columnconfigure(0, weight = 1)
        self.parent.config(background = "lavender")    

        self.label_welcome = Tkinter.Label(self.parent,text="Not a member? Please sign up: ",anchor=Tkinter.W,background="dark slate gray",foreground="white", font="Helvetica 8  bold")
        self.label_welcome.grid(row = 0, columnspan = 2, stick = Tkinter.E + Tkinter.W)

        self.button_signup = Tkinter.Button(self.parent,font="Helvetica 10 bold", text = "Sign up", command = self.signup)
        self.button_signup.grid(row = 1, column = 0, sticky = Tkinter.E + Tkinter.W)
        self.button_cancel_signup = Tkinter.Button(self.parent,text = "Cancel",font="Helvetica 10 bold", command = self.parent.quit)
        self.button_cancel_signup.grid(row = 1, column = 1, sticky = Tkinter.E + Tkinter.W)

然后，我们编程第二个方法，例如，

signup（）

，以绘制第二个GUI来正确显示订阅元素

1。第一个技巧：

但您的问题是如何将

self.button\u signup

绑定到

signup（）

方法。可以使用修改器解决此问题：

self.button_signup = Tkinter.Button(command = self.signup)

2。第二个窍门：

您面临的第二个问题的解决方案是使用以下方法将上面的第二个（最大）窗口显示为第一个（小）窗口的子窗口：

3。完整应用程序：

以下是在单个模块中编码的完整应用程序：

def main():
    root = Tkinter.Tk()
    b = Begueradj(root)
    b.mainloop()
# Start of the main program
if __name__ == "__main__":
    main()

第二种方法： 第二种方法是将前一种方法拆分为两种独立的方法，即login.py和signup.py，从而尊重您自己的设计

1。signup.py:

在这里，您保留了之前重命名的

signup（）

方法。为方便起见，通过

signup.py

模块中的

subscribe（）

，但您需要将

Tkinter.Frame

小部件传递给此模块唯一类的构造函数，以便能够使用该方法：

2。login.py

from Tkinter import *
import Signup

class Login():
    def __init__(self):
        self.root = Tk()
        self.root.title("Welcome to Login")
        self.btnSignup = Button(self.root, text="Not a member? Sign up now!", relief=FLAT,
                                borderwidth=1, font=("Century Gothic",11,'normal'),
                                command = self.callSignup, fg="white",bg="#0866c6", 
                                activebackground="#404040",activeforeground="white")
        self.btnSignup.place(width = 250, height = 25, x = 10, y = 10)
        self.root.mainloop()

    def callSignup(self):
        self.root.destroy()
        self.obj = Signup.signup("james")
        self.obj.display()

from Tkinter import *

class signup():
    def __init__(self,name):
        self.name = name

    def display(self):
        self.root = Tk()
        self.root.title("Welcome " + self.name)            
        self.root.mainloop()

此模块包含前面的

初始化\u成员资格\u接口（）

方法

这里的主要技巧是如何绑定signup.py的

subscribe（）

方法，并成功地将login.py模块的main

Tkinter.Frame

小部件传递到

按钮\u signup

按钮。这是这样做的：

self.button_signup = Tkinter.Button(self.parent, text = "Sign up", command = signup.Signup(self.parent).subscribe)

3。完整应用程序：

以下是两个模块的内容：

• 注册。py：

当然，主要方法（程序启动）与本模块无关：

请注意，运行我在这里介绍的两个版本的解决方案会产生以下GUI：

如果你想获得与上面截图中相同的按钮视觉效果，你需要使用这个和那个图像

要将这些图片加载到各自的按钮中，首先需要导入：

from PIL import Image, ImageTk

然后，您需要将图像设置为两个按钮的背景：

# Setting images to the buttons
self.img_signup = ImageTk.PhotoImage(Image.open("img.png").resize((100,40),Image.ANTIALIAS))
self.img_cancel = ImageTk.PhotoImage(Image.open("cancel.png").resize((100,40), Image.ANTIALIAS))
self.button_signup = Tkinter.Button(self.parent, image = self.img_signup,command = self.signup)
self.button_signup.grid(row = 1, column = 0, sticky = Tkinter.E + Tkinter.W)
self.button_cancel_signup = Tkinter.Button(self.parent, image = self.img_cancel, command = self.parent.quit)
self.button_cancel_signup.grid(row = 1, column = 1, sticky = Tkinter.E + Tkinter.W)

我将用两种方法解决您的问题

因此，基本上，您正在寻找：

• 用户单击“注册”按钮：

• 单击必须提示一个注册窗口：

第一种方法： 第一种方法建议重新设计您的应用程序：我的意思是，为了完成此任务（实际上），最好将窗口集中在同一个模块中，而不是两个单独的

login.py

和

signup.py

模块。我更倾向于从方法开始，因为它有第二个优点，可以简单地解决您的问题。让我们调用我们的模块

loginsignup.py

在类的构造函数中，在构造函数中设置框架小部件：

def __init__(self, parent):
        Tkinter.Frame.__init__(self, parent)
        self.parent = parent

为了更好的设计，最好在单独的函数中分离GUI设计，例如，

initialize\u membership\u interface（）

。当然，必须在上面的构造函数主体中调用此方法：

def __init__(self, parent):
        Tkinter.Frame.__init__(self, parent)
        self.parent = parent
        self.initialize_membership_interface()

初始化成员资格接口（）

实例化2个按钮和一个标签。使用该方法在框架内组织这3个小部件：

def initialize_membership_interface(self):
        self.parent.title('Membership Area')
        self.parent.grid_rowconfigure(0, weight = 1)
        self.parent.grid_columnconfigure(0, weight = 1)
        self.parent.config(background = "lavender")    

        self.label_welcome = Tkinter.Label(self.parent,text="Not a member? Please sign up: ",anchor=Tkinter.W,background="dark slate gray",foreground="white", font="Helvetica 8  bold")
        self.label_welcome.grid(row = 0, columnspan = 2, stick = Tkinter.E + Tkinter.W)

        self.button_signup = Tkinter.Button(self.parent,font="Helvetica 10 bold", text = "Sign up", command = self.signup)
        self.button_signup.grid(row = 1, column = 0, sticky = Tkinter.E + Tkinter.W)
        self.button_cancel_signup = Tkinter.Button(self.parent,text = "Cancel",font="Helvetica 10 bold", command = self.parent.quit)
        self.button_cancel_signup.grid(row = 1, column = 1, sticky = Tkinter.E + Tkinter.W)

然后，我们编程第二个方法，例如，

signup（）

，以绘制第二个GUI来正确显示订阅元素

1。第一个技巧：

但您的问题是如何将

self.button\u signup

绑定到

signup（）

方法。可以使用修改器解决此问题：

self.button_signup = Tkinter.Button(command = self.signup)

2。第二个窍门：

您面临的第二个问题的解决方案是使用以下方法将上面的第二个（最大）窗口显示为第一个（小）窗口的子窗口：

3。完整应用程序：

以下是在单个模块中编码的完整应用程序：
