You can use exec("self." + name + " = " + value) to do what you want,
but then you need to exec() each time you want to access the
variable. I think it is much better to create a class.
Here's what I came up with:
from Tkinter import *
class Window(Frame):
def __init__(self, parent=None):
Frame.__init__(self,parent=None)
self.names = ["LNCOL", "LFORM", "LPOT", "LGRID", "LERR",
"LCOMP",
"Sean"]
self.checkbuttons = []
self.f = Frame(root)
for name in self.names:
self.checkbuttons.append(CButton(parent=self.f,
name=name,
default="f"))
self.f.pack(side="top",padx=5, pady=5)
class CButton(object):
def __init__(self, parent=None, name=None, default=None):
self.name = name
self.parent = parent
self.variable = StringVar()
self.variable.set(default)
self.checkbutton = None
self.create_checkbox(name)
def create_checkbox(self,name):
f = Frame(self.parent)
Label(f, text=name).pack(side="left")
self.checkbutton = Checkbutton(f, onvalue='t', offvalue='f',
variable=self.variable)
self.checkbutton.bind("<Button-1>", self.state_changed)
self.pack()
f.pack()
def pack(self):
self.checkbutton.pack()
def state_changed(self, event=None):
print "%s: %s" % (self.name, self.variable.get())
if __name__ == '__main__':
root = Tk()
Window().mainloop()
