i trying use ttk.notebook in python3 on linux (ubuntu 14.04lts) system read blockquote`# -- coding: utf-8 --data experiments , perform several curve fits on data in order calculate coefficients needed finite element calculation. actual calculation of these curves have performed without tkinter. setting user interface. works well, until want fill in variable global variable, noting exported ipython shell (using spyder2). variables: creepdata , path2 made global in same way visble in ipython shell. not sure if way extracting values combo boxes or entry fields on notebook page select units , run work in intended way. see code below:

changed - sorry did not understand question, prehaps more helpful:
first i'd recommend taking @ both of these:
share variables between methods
second, creating input entries in _create_select_units_run_tab , do:
def _create_select_units_run_tab: ... = cb1.get() ... this contents after being created , before .mainloop() called absolutely empty string, in order content later in _run1 need keep track of entries instead:
def _create_select_units_run_tab: ... self.input_fields = [cb1,cb2,cb3,ym,isf] #this give other methods access input fields #then them can use this: def get_inputs(self): return [entry.get() entry in self.input_fields] #then in run can data in fields def _run1(self, w): inp_data = self.get_inputs() print(inp_data) if "" in inp_data: w.set("you need fill everthing in first!") else: w.set(str(inp_data)) ... while testing code cancelled file dialog window threw error because path2 == "" may want check:
def askopenfilename2(self): ... if path2 not "": creepreader=csv.reader(open(path2, newline=""), delimiter=',') creepdata = list(creepreader) #else: # creepdata = none # or leave last used value? ... not mention open() never closed (input , output python documentation):
it practice use keyword when dealing file objects. has advantage file closed after suite finishes, if exception raised on way. shorter writing equivalent `try-finally` blocks: open('workfile', 'r') f: ... read_data = f.read() >>> f.closed true so may want implement too:
open(path2, newline="") file_obj: creepreader=csv.reader(file_obj, delimiter=',') lastly i'd draw attention to:
self.after(500,w.set('') w.set('') being called , using return value none in self.after, instead call w.set argument need this:
self.after(500,w.set,'') then tkinter call after 500ms forwarding arguments receives in after
there may other issues code missed hope helped.
