tkinter multilistbox lists are independent of each other

问题

enter image description hereI want to create multiple lists with this code and let the lists I create work with each other. When I make mlb.get (ACTIVE), the value in the list is clicked. The get command is not synchronized with other lists. The info function creates a section on the side and lists the information on the clicked line. The MULTILISTBOX class needs to make lists and work together.

class MultiListbox(Frame):
    def __init__(self, master, lists):
        Frame.__init__(self, master)
        self.lists = []
        for l, w in lists:
            frame = Frame(self);
            frame.pack(side=LEFT, expand=YES, fill=BOTH)
            Label(frame, text=l, borderwidth=1, relief=RAISED).pack(fill=X)
            lb = Listbox(frame, width=w, borderwidth=0, selectborderwidth=0,
                         relief=FLAT, exportselection=FALSE)
            lb.pack(expand=YES, fill=BOTH)
            self.lists.append(lb)
            lb.bind('<B1-Motion>', lambda e, s=self: s._select(e.y))

Question: Multiple Listbox in class MultiListbox should behave in sync by clicked in one Listbox.

Change/add the following:

Bind to event '<<ListboxSelect>>'

class MultiListbox(Frame):
    def __init__(self, master, lists):
        ...
        for l, w in lists:
            ...
            lb.bind('<<ListboxSelect>>', self.on_select)

Change your global def info(): to a class method def on_select(...

def on_select(self, event):
    w = event.widget
    curselection = w.curselection()

    if curselection:
        self.selection_clear(0, self.size())
        self.selection_set(curselection)

        mlb_get = mlb.get(curselection)
        yazi.config(text=mlb_get)
        print(mlb_get)

In __main__ remove the statement: info()
```
# info()
```
