Tkinter CheckBox实现单选和多选

单选：

self.light_list = ["1000Lux_SME_D65_EV_0", "1000Lux_SME_D65_EV_10", "1000Lux_SME_D65_EV_20",
                           "100Lux_SME_A_EV_0",
                           "20Lux_SME_A_EV_0", "5Lux_SME_A_EV_0", "1Lux_SME_H_EV_0"]

self.CheckList = IntVar()

for i in range(0, len(self.light_list)):
            self.v.append(IntVar())
            checkbox = Checkbutton(self.fm2_left_top, text=self.light_list[i], variable=self.CheckList, onvalue=i,
                                   command=self.showSelection)
            checkbox.pack(side=TOP)
self.CheckList.set(0)

def showSelection(self):
    self.write_log_to_Text("INFO:{} success".format(self.light_list[self.CheckList.get()]))

 

 

 

多选：

self.light_list = ["1000Lux_SME_D65_EV_0", "1000Lux_SME_D65_EV_10", "1000Lux_SME_D65_EV_20",
                           "100Lux_SME_A_EV_0",
                           "20Lux_SME_A_EV_0", "5Lux_SME_A_EV_0", "1Lux_SME_H_EV_0"]

self.v = []

        for i in range(0, len(self.light_list)):
            self.v.append(IntVar())
            checkbox = Checkbutton(self.fm2_left_top, text=self.light_list[i], variable=self.v[-1], onvalue=i+1,
                                   command=self.showSelection)
            checkbox.pack(side=TOP)

def showSelection(self):
        seleds = []
        for i in self.v:
            if i.get() > 0:
                seleds.append(self.light_list[i.get()-1])
        for seld in seleds:
            self.write_log_to_Text("INFO:{} success".format(seld))

 onvalue=i+1: 因为i是从0开始，Checkbox未选中的情况下也是0,导致onvalue=0时，从light_list中获取到第一个值，从而增一操作，当checkbox选中后onvalue是永远大于一，所以只要判断 i.get()>0就可以知道是否选中.

for i in self.v:

　　 if i.get() > 0:

    　　seleds.append(self.light_list[i.get()-1])
