Hi,
I searched the web and docs but cannot figure out whats wrong with this
code:
#!/usr/bin/python
import Tkinter as Tk
class testtk(Tk.Frame):
def __init__(self):
self.root = Tk.Tk()
Tk.Frame.__init__(self,self.root)
self.frame = Tk.Frame(self.root)
self.var = Tk.StringVar()
self.var.trace_variable('w',self.check)
Tk.Entry(self.frame, textvariable = self.var).pack()
self.frame.pack()
Tk.mainloop()
def check():
pass
if __name__ == "__main__":
t = testtk()
t.var.set("TEST")
Result:
Traceback (most recent call last):
File "<stdin>", line 22, in ?
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 191, in set
return self._tk.globalsetvar(self._name, value)
_tkinter.TclError: can't set "PY_VAR0": invalid command name
"-1210125972check"
Any ideas, why I cant set the variable var?
