在tkinter GUI中使用多個窗口

Question

我正在python中構建一個非常基礎的電影推薦GUI，我試圖讓它在選擇流派時打開一個新窗口。我可以打開窗口，但我無法將單選按鈕分配給新班級。我希望能夠選擇一種流派，然後點擊下一步，並根據用戶選擇的按鈕開始我的推薦。

from tkinter import * 
class movie1: 
    def __init__(self, master): 
     self.master = master 
     master.title("Movie Recommendation") 

     self.label = Label(master, text= "Welcome to the movie recommendation application! \n Please select the genre of the movie you would like to see.") 
     self.label.pack(padx=25, pady=25) 

     CheckVar1 = StringVar() 

     C1 = Radiobutton(master, text = "Action", variable = CheckVar1, value=1) 
     C1.pack(side=TOP, padx=10, pady=10) 
     C2 = Radiobutton(master, text = "Comedy", variable = CheckVar1, value=2) 
     C2.pack(side=TOP, padx=10, pady=10) 
     C3 = Radiobutton(master, text = "Documentary", variable = CheckVar1, value=3) 
     C3.pack(side=TOP, padx=10, pady=10) 
     C4 = Radiobutton(master, text = "Horror", variable = CheckVar1, value=4) 
     C4.pack(side=TOP, padx=10, pady=10) 
     C5 = Radiobutton(master, text = "Romance", variable = CheckVar1, value=5) 
     C5.pack(side=TOP, padx=10, pady=10) 

     self.nextbutton = Button(master, text="Next", command=self.reco) 
     self.nextbutton.pack(side=BOTTOM, padx=10, pady=10) 

    def reco(self): 
     self.newWindow = Toplevel(self.master) 
     self.app = movie2(self.newWindow) 

class movie2: 
    def __init__(self, master): 
     self.master = master 
     self.frame = Frame(self.master) 

    def C1(self): 
     print("option 1")  


root = Tk() 
my_gui = movie1(root) 
root.mainloop() 

Answer 1

您可以選擇的值傳遞給新類：

class movie1: 
    def __init__(self, master): 
     ... 
     self.CheckVar1 = StringVar() 
     ... 

    def reco(self): 
     ... 
     choice = self.CheckVar1.get() 
     self.app = movie2(self.newWindow, choice) 

class movie2: 
    def __init__(self, master, choice): 
     ... 
     print("you chose: %s" % choice) 
     ...
