Question

我想创建一个tkinter小部件，在其中为不同的参数手动添加值。

import tkinter as tk
import tkinter.messagebox

class MainApplication(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)
        self.parent = parent
        #Size of the window
        root = tk.Tk()
        root.geometry('1000x1000') 

        #Scrollbar 
        scrollbar = tk.Scrollbar(root)
        scrollbar.pack( side = 'right', fill = 'y' )
        #Description show in window
        info=tk.Label(root)
        info.pack()

#Parameters

        parameters = ('Number of pipes', 'Anisotropy ratio', 'Filter depth (in cm)')

    def ask_parameter():

        user_pipes = float (entry['num_pipes (default = 2)'].get()) #effective radius well casing (1.685), corrected for radius transponder (0.3)
        if user_pipes == entry['num_pipes (default = 2)'].get():
            num_pipes = user_pipes
        else:
            num_pipes = 2 

        user_aniso = float (entry['aniso (default = 1)'].get()) #effective screen length = b
        if user_aniso == entry['aniso (default = 1)'].get():
            aniso = user_aniso
        else:
            aniso = 1

        user_depth = float (entry['filter_depth (default = 20)'].get()) #effective radius slug test = effective radius well screen (see fetter p. 194)
        if user_depth == entry['filter_depth (default = 20)'].get():
            filter_depth = user_depth
        else:
            filter_depth = 20


    def form():
        entry = {}
        for parameter in parameters:
    #        print(parameter)
            row = tk.Frame(root)
            lab = tk.Label(row, width=15, text=parameter+": ", anchor='w')
            ent = tk.Entry(row)      
            row.pack(side=tk.TOP, 
                     fill=tk.X, 
                     padx=2, 
                     pady=2)
            lab.pack(side=tk.LEFT)
            ent.pack(side=tk.RIGHT, expand=tk.YES,fill=tk.X)
            entry[parameter] = ent
        return entry

if __name__ == "__main__":
    root = tk.Tk()
    MainApplication(root).pack(side="top", fill="both", expand=True)
    root.mainloop()

save_button = tk.Button(root)
save_button.configure(text='Save', command=ask_parameter)
save_button.pack()
root.mainloop()

我没有实现用user_pipes，user_aniso和user_depth的值创建三个变量。我遇到下一个错误：

return self.func(*args), TypeError: ask_parameter() missing 1 required positional argument: 'entry'

我想用用户选择的值创建3个变量。

现在，我添加了您的修改并给出了下一个错误： TclError：无法调用“按钮”命令：应用程序已被破坏

Tkinter，滚动条，TypeError：缺少1个必需的位置参数
