Python表单:使用TKinter - >基于GUI中选中的复选框运行脚本 [英] Python Form: Using TKinter --> run script based on checked checkboxes in GUI
问题描述
我使用tkinter(参见图片)在Python 3.5中创建了以下复选框弹出窗口,其中包含以下代码:
I have created the following checkbox popup in Python 3.5 using tkinter (see image) with the following code:
from tkinter import *
class Checkbar(Frame):
def __init__(self, parent=None, picks=[], side=LEFT, anchor=W):
Frame.__init__(self, parent)
self.vars = []
for pick in picks:
var = IntVar()
chk = Checkbutton(self, text=pick, variable=var)
chk.pack(side=side, anchor=anchor, expand=YES)
self.vars.append(var)
def state(self):
return map((lambda var: var.get()), self.vars)
if __name__ == '__main__':
root = Tk()
lng = Checkbar(root, ['DerVar1', 'DerVar2', 'DerVar3', 'DerVar4', 'DerVar5', 'DerVar6', 'DerVar7', 'DerVar8'])
tgl = Checkbar(root, ['DerVar9','DerVar10', 'DerVar11', 'DerVar12', 'DerVar13', 'DerVar14'])
lng.pack(side=TOP, fill=X)
tgl.pack(side=LEFT)
lng.config(relief=GROOVE, bd=2)
def allstates():
print(list(lng.state()), list(tgl.state()))
Button(root, text='Quit', command=root.quit).pack(side=RIGHT)
Button(root, text='Run', command=allstates).pack(side=RIGHT)
root.mainloop()
如你所见,我检查了'DerVar2'和DerVar3'。单击运行后,我将以黄色突出显示以下内容。
As you can see I have checked 'DerVar2' and DerVar3'. After I click run I get the following highlighted in yellow.
正如您所见,1对应于要检查的复选框。
As you can see a 1 corresponds to a checkbox getting checked.
变量'lng'是一个复选框对象。我想说如果检查'DerVar2',然后打印'test'但无法使其工作。
the variable 'lng' is a checkbar object. I want to say if 'DerVar2' is checked, then print 'test' but can't get it to work.
这是我试过的代码,下面是我得到的错误:
This is the code I have tried and below is the error I get:
if lng[1] == 1:
print ('test')
TypeError:无法将'int'对象隐式转换为str
TypeError: Can't convert 'int' object to str implicitly
推荐答案
问题是你的 Checkbar
类没有 __ getitem __
方法所以 lng [1]
将触发错误。要做 lng [1] == 1
而不出错,只需将以下方法添加到r Checkbar
class:
The problem is that your Checkbar
class has no __getitem__
method so lng[1]
will trigger an error. To do lng[1] == 1
without errors, just add the following method to you rCheckbar
class:
def __getitem__(self, key):
return self.vars[key].get()
那样 lng [i]
将返回值i-th
Checkbar的IntVar
That way lng[i]
will return the value of the i-th IntVar
of the Checkbar
