PythonTkinter網格不適用于類

如何使用網格系統更改按鈕的位置？

我讓它在沒有課的情況下作業。

當我運行程式時，它會忽略網格設定...

我想使用網格系統，但它不起作用。

這是它現在的樣子：

但我想要這樣的東西：

提前致謝

import os

uj5u.com熱心網友回復：

您使用grid了錯誤的小部件。你把 eachttk.Button放在 new 中，Button(Frame)所以self.button.grid在Button(Frame)eachttk.Button中創建新網格，它放在這個新框架中，而不是放在 main 的主網格中Frame。因為ttk.Button這個網格中只有一個，所以它顯示在同一個地方。網格中的空行和列沒有寬度和高度。

每一個都沒有Button(Frame)使用，所以它把每一個Frame`。self.gridcolumn=row=Button(Frame) in new row in main

你將不得不使用column=，row=以self.grid代替self.button.grid

        # put `ttk.Button` in current `Button(Frame)`
        self.button.pack()  
        
        # put current `Button(Frame)` in main `Frame`
        self.grid(column=col, row=row, sticky=tk.W, **opt)

最小作業代碼：

import os
import tkinter as tk
from tkinter import ttk
from tkinter.messagebox import showerror
from tkinter.filedialog import askdirectory


class Frame(ttk.Frame):
    def __init__(self, container):
        self.options = {'padx': 5, 'pady': 5}
        super().__init__(container)
        self.grid(padx=5, pady=5, sticky=tk.NSEW)


class Button(Frame):
    def __init__(self, container, text, col, row, opt):
        super().__init__(container)
        self.path = tk.StringVar()
        self.button = ttk.Button(self, text=text)
        self.button['command'] = self.selectpath
        
        # put `ttk.Button` in current `Button(Frame)`
        self.button.pack()  
        
        # put current `Button(Frame)` in main `Frame`
        self.grid(column=col, row=row, sticky=tk.W, **opt)

    def selectpath(self):
        path_ = tk.filedialog.askdirectory()
        self.path.set(path_)


class App(tk.Tk):
    def __init__(self):
        super().__init__()
        tk_width = 330
        tk_height = 150
        self.geometry(str(tk_width)   'x'   str(tk_height))
        x_left = int(self.winfo_screenwidth() / 4 - tk_width / 2)
        y_top = int(self.winfo_screenheight() / 2 - tk_height / 2)
        self.geometry(' {} {}'.format(x_left, y_top))
        self.resizable(False, False)

if __name__ == "__main__":
    app = App()
    window = Frame(app)
    selectbutton = Button(window, 'hello' , 2, 0, window.options)
    selectbutton = Button(window, '1hello', 1, 1, window.options)
    app.mainloop()

編輯：

如果你用 createButton(ttk.Button)而不是，也許你就不會遇到這個問題Button(Frame)

class Button(ttk.Button):

    def __init__(self, container, text, col, row, opt):
        super().__init__(container, text=text, command=self.selectpath)
        self.path = tk.StringVar(self)
        self.grid(column=col, row=row, sticky=tk.W, **opt)

    def selectpath(self):
        path = tk.filedialog.askdirectory()
        if path:
            self.path.set(path)

import os
import tkinter as tk
from tkinter import ttk
from tkinter.messagebox import showerror
from tkinter.filedialog import askdirectory


class Frame(ttk.Frame):
    
    def __init__(self, master):
        super().__init__(master)
        self.options = {'padx': 5, 'pady': 5}
        self.grid(padx=5, pady=5, sticky=tk.NSEW)


class Button(ttk.Button):

    def __init__(self, master, text, col, row, opt):
        super().__init__(master, text=text, command=self.selectpath)
        self.path = tk.StringVar(self)
        self.grid(column=col, row=row, sticky='w', **opt)

    def selectpath(self):
        path = tk.filedialog.askdirectory()
        if path:
            self.path.set(path)


class App(tk.Tk):

    def __init__(self):
        super().__init__()

        tk_width = 330
        tk_height = 150

        x_left = int(self.winfo_screenwidth()  / 4 - tk_width  / 2)
        y_top  = int(self.winfo_screenheight() / 2 - tk_height / 2)

        self.geometry(f'{tk_width}x{tk_height} {x_left} {y_top}')

        self.resizable(False, False)


if __name__ == "__main__":
    app = App()
    window = Frame(app)
    selectbutton = Button(window, 'hello' , 2, 0, window.options)
    selectbutton = Button(window, '1hello', 1, 1, window.options)
    app.mainloop()
