如何在 tkinter 中动态创建选项卡 [英] How do I create tabs in tkinter dynamically

问题描述

我创建了一个菜单栏，其中包含打开、编辑等选项.打开的下拉菜单说打开文件，保存文件和另存为.我想以这样的方式设计 GUI，当单击打开并选择文件时，我希望文件内容显示在新选项卡中，当我单击另一个选项时，我希望它显示在另一个选项卡中.有人可以帮我解决这个问题吗?

I have creatd a menu bar that has options open , edit and some more. The dropmenu in open says open file , save file and save as. I want to design the GUI in such a way that when click open and choose the file , I want the file contents to be displayed in a new tab and when I click another option I want it to be displayed in another tab. Can anybody help me with this?

推荐答案

这是你想要的代码吗(简单例子):

Is this the code You want (simple example):

from tkinter import Tk, Menu, Text
from tkinter.ttk import Notebook
from tkinter.filedialog import askopenfile


text_list = []


def add_tab(parent, contents, name):
    text = Text()
    text_list.append(text)
    text = text_list[len(text_list) - 1]
    
    parent.add(text, text=name)
    text.insert('end', contents)


def open_file():
    file = askopenfile(filetypes=[('Text file', '*.txt')])

    if file:
        add_tab(notebook, file.read(), file.name.split('/')[-1])


root = Tk()

menu_bar = Menu(root)

file_menu = Menu(menu_bar, tearoff=0)
menu_bar.add_cascade(label='File', menu=file_menu)
file_menu.add_command(label='Open', command=open_file)

root.config(menu=menu_bar)

notebook = Notebook(width=700, height=500)
notebook.pack()

root.mainloop()

对此没什么好说的，唯一要补充的是，在使用选项卡和文本时，您需要以某种方式存储文本小部件的索引，以便您始终可以访问它(以对该特定文本小部件执行操作)(我可以说这并不容易)但到目前为止，这有效并且符合您的要求.

There is not much to say about this, the only thing to add is that when using tabs and text You need to somehow store the index of text widget so that You can always access it (to perform actions on that specific text widget) (and I can tell that it won't be easy) but so far this works and does what You asked for.
