I've searched everywhere on the web but unfortunately no where did
I find an answer to this question:

after setting a tkinter Entry() widget's textvariable to a textvariable.

the text variable does not update after I have typed text into the entry.

code below:

def saveFileName(self):

    if(self.save_file_name != ""):

        self.window.destroy()

        self.name_not_set = False

        print("saving...")

    else:

        print("notsaving...entry empty")

        pass

def cancel(self):

    self.name_not_set = False

    self.exit = True

    self.window.destroy()

    print("exiting...")

def askForFilename(self):

    self.window = tk.Tk()

    self.window.wm_title("enter a file name")

    label = Label(self.window,text="please enter a file name:").pack(side="top")

    entry = Entry(self.window,textvariable=self.save_file_name).pack()

    save = Button(self.window,text="save",command=self.saveFileName).pack()

    cancel = Button(self.window,text="cancel",command=self.cancel).pack()

    self.window.mainloop()

The necessary variables have been defined and these methods are part
of a class which is a tk.TK() instance.

this problem is very bothersome
:( very sad :(

Thank you and merry christmas in advance!

A textvariable associated with an Entry should be a StringVar(). I don't se any such declaration in your code.

self.save_file_name = StringVar()

To set and get the value of a StringVar() you must use the set() or get() method, eg.

def saveFileName(self):

    if(self.save_file_name.get() != ""):

        self.window.destroy()

        # etc, etc.

Also, don't create more than one instance of Tk() as in:

def askForFilename(self):

    self.window = tk.Tk()

Use Toplevel() instead. Or even better: use the tkinter filedialogs.
