其实有这个样式选项- tabposition 。
import tkinter as tkfrom tkinter import ttkroot = tk.Tk()root.minsize(300, 300)root.geometry("1000x700")s = ttk.Style()s.configure('TNotebook', tabposition='ne') #'ne' as in compass directionbox = ttk.Notebook(root, width=1000, height=650)tab1 = tk.frame(root)tab2 = tk.frame(root)tab3 = tk.frame(root)box.add(tab1, text="tab1")box.add(tab2, text="tab2")box.add(tab3, text="tab3")box.pack(side=tk.TOP)root.mainloop()
