收集多个 Tkinter 检查按钮的输出

Question

我有一个包含devices = {'dev1': ['192.168.200.73', 'foo', 'bar'], 'dev2': ['192.168.200.109', 'foo', 'bar']} 之类的数据的字典，我将字典打印为检查按钮，我需要获取选定的检查按钮名称。基本代码：

for name in devices:
v1 = BooleanVar()
c= Checkbutton(top, text=name, variable= v1)
c.grid(columns=1, rows= rs)
rs +=1

谢谢。

from tkinter import *

root = Tk()

devices = {'dev1': ['192.168.2.73', 'foo', 'bar'],
           'dev2': ['192.168.2.109', 'foo', 'bar']}

check_dict = dict() # Dict of checkbox names and IntVars
for name in devices:
    var = IntVar()      # Create an IntVar for the checkbox
    chk = Checkbutton(root, text=name, variable=var, onvalue = 1, 
                      offvalue = 0, height=5, width = 20)
    chk.pack()
    check_dict[name] = var  # Save name and IntVar reference

def go(event):  # Prints out all checkbox IntVars on <space>
    for name, var in check_dict.items():
        print(name, var.get())

root.bind('<space>', go)
root.mainloop()

使用列表和网格的示例：

from tkinter import *

root = Tk()

devices = {'dev1': ['192.168.2.73', 'foo', 'bar'],
           'dev2': ['192.168.2.109', 'foo', 'bar']}

check_list = [] # List of chexkbox names and IntVars
for name in devices:
    var = IntVar()          # Create an IntVar for the checkbox
    chk = Checkbutton(root, text=name, variable=var, onvalue = 1, 
                      offvalue = 0, height=5, width = 20)
    chk.grid()
    check_list.append([name,var])  # Save name and IntVar reference

def go(event):  # Prints out all checkbox IntVars on <space>
    for v in check_list:
        print(v[0], v[1].get())

root.bind('<space>', go)
root.mainloop()
