如何将Treeview列标题制作为Button？

如何解决如何将Treeview列标题制作为Button？

我试图通过在标题上添加按钮来改善GUI的功能，但是找不到与此有关的任何示例或信息。在此示例中，是否可以将标题变成可点击的按钮？ Treeview将从数据库中填充，因此，如果我可以使用按钮，那意味着我可以用比“盒子”外面有更多按钮更好的方式订购显示器。

import tkinter as tk
from tkinter import ttk

screen = tk.Tk() 
screen.title('This One')
screen.geometry('890x400')
style = ttk.Style()
style.theme_use("clam")
screen.grid_rowconfigure(1,weight=1)
screen.grid_columnconfigure(0,weight=1)

cols = ('TOKEN','F-500','F-250','F-100','F-24','POS','NEG')
Box = ttk.Treeview(screen,columns=cols,show='headings')
for col in cols:
    Box.heading(col,text=col)
    Box.grid(row=1,column=0,columnspan=2,sticky='nsew')


Box.column("TOKEN",width=95)
Box.column("F-500",width=85,anchor='e')
Box.column("F-250",anchor='e')
Box.column("F-100",anchor='e')
Box.column("F-24",anchor='e')
Box.column("POS",width=75,anchor='center')
Box.column("NEG",anchor='center')



closeButton = tk.Button(screen,text="Close",width=15,command=exit).grid(row=10,column=0)

screen.mainloop()

解决方法

Treeview的标题已经是带有可选关键字pygame.sprite.Sprite的按钮。要在forloop中使用此功能，可以使用command和annoynmous function。

lambda

不使用lambda：

import tkinter as tk
from tkinter import ttk

screen = tk.Tk() 
screen.title('This One')
screen.geometry('890x400')
style = ttk.Style()
style.theme_use("clam")
screen.grid_rowconfigure(1,weight=1)
screen.grid_columnconfigure(0,weight=1)

cols = ('TOKEN','F-500','F-250','F-100','F-24','POS','NEG')
box = ttk.Treeview(screen,columns=cols,show='headings')
for col in cols:
    if col == 'TOKEN':
        box.heading(col,text=col,command =lambda: print('token'))
    box.grid(row=1,column=0,columnspan=2,sticky='nsew')


box.column("TOKEN",width=95)
box.column("F-500",width=85,anchor='e')
box.column("F-250",anchor='e')
box.column("F-100",anchor='e')
box.column("F-24",anchor='e')
box.column("POS",width=75,anchor='center')
box.column("NEG",anchor='center')



closeButton = tk.Button(screen,text="Close",width=15,command=exit).grid(row=10,column=0)

screen.mainloop()
