有没有办法把定制笔记本和普通笔记本结合起来,这样所有的标签都可以打开

不久前我在这里发现了允许在tkinter中的笔记本选项卡上添加关闭按钮的代码,但是我希望能够将常规笔记本(没有关闭按钮)与自定义笔记本结合起来。当我试着这样做的时候,我得到了一组常规笔记本的标签,然后在它下面是另一组定制笔记本的标签

正如所建议的,我已经包括了下面的图片,显示了目前发生的事情,但我要找的是有所有的标签在一起(其中红色将与橙色,绿色,蓝色等标签线),但不会有x允许它被关闭

Not what I want

我一直试图修改的代码是:

import tkinter as tk
import tkinter.ttk as ttk

#----------------------------------------------------------

class CustomNotebook(ttk.Notebook):
    '''
    A ttk Notebook with close buttons
    on each tab
    '''
    __initialized = False

    #------------------------------------------------------
    def __init__(self, *args, **kwargs):
        if not self.__initialized:
            self.__initialize_custom_style()
            self.__inititialized = True

        kwargs['style'] = 'CustomNotebook'
        ttk.Notebook.__init__(self, *args, **kwargs)

        self._active = None

        self.bind('<ButtonPress-1>', self.on_close_press, True)
        self.bind('<ButtonRelease-1>', self.on_close_release)

    #------------------------------------------------------
    def on_close_press(self, event):
        '''
        Called when the button is pressed
        over the close button
        '''
        element = self.identify(event.x, event.y)

        if 'close' in element:
            index = self.index('@%d,%d' % (event.x, event.y))
            self.state(['pressed'])
            self._active = index

    #------------------------------------------------------
    def on_close_release(self, event):
        '''
        Called when the button is released
        over the close button
        '''
        if not self.instate(['pressed']):
            return

        element =  self.identify(event.x, event.y)
        index = self.index('@%d,%d' % (event.x, event.y))

        if 'close' in element and self._active == index:
            self.forget(index)
            self.event_generate('<<NotebookTabClosed>>')

        self.state(['!pressed'])
        self._active = None

    #------------------------------------------------------
    def __initialize_custom_style(self):
        style = ttk.Style()
        self.images = (
            tk.PhotoImage('img_close', data='''
                R0lGODlhCAAIAMIBAAAAADs7O4+Pj9nZ2Ts7Ozs7Ozs7Ozs7OyH+EUNyZWF0ZWQg

                ''')
            )

        style.element_create('close', 'image', 'img_close',
            ('active', 'pressed', '!disabled', 'img_closepressed'),
            ('active', '!disabled', 'img_closeactive'), border=8, sticky='')
        style.layout('CustomNotebook', [('CustomNotebook.client', {'sticky': 'nswe'})])
        style.layout('CustomNotebook.Tab', [
            ('CustomNotebook.tab', {
                'sticky': 'nswe', 
                'children': [
                    ('CustomNotebook.padding', {
                        'side': 'top', 
                        'sticky': 'nswe',
                        'children': [
                            ('CustomNotebook.focus', {
                                'side': 'top', 
                                'sticky': 'nswe',
                                'children': [
                                    ('CustomNotebook.label', {'side': 'left', 'sticky': ''}),
                                    ('CustomNotebook.close', {'side': 'left', 'sticky': ''}),
                                ]
                            })
                        ]
                    })
                ]
            })
        ])

#----------------------------------------------------------

if __name__ == '__main__':
    root = tk.Tk()

    note = ttk.Notebook(width=200, height=200)
    note.pack(side='top', fill='both', expand=True)
    notebook = CustomNotebook(width=200, height=200)
    notebook.pack(side='top', fill='both', expand=True)

    for color in ('red', 'orange', 'green', 'blue', 'violet'):
        if color == 'red':
            frame = tk.Frame(note, background=color)
            note.add(frame, text=color)
        else:
            frame = tk.Frame(notebook, background=color)
            notebook.add(frame, text=color)

    root.mainloop()

我猜我必须使用自定义笔记本,并导致其中一个选项卡不使用关闭功能,但我不知道如何实现这一点。非常感谢您的帮助

我还要感谢bryanoakley提供了CustomNotebook类,我在下面的帖子中找到了这个类:Is there a way to add close buttons to tabs in tkinter.ttk.Notebook?
