Save Changed Textbutton State Back To Dictionary Value List Index 0

Good Day. I have managed to load a dictionary from a text file with this code: def loadDictFile(data_folder): critDict = json.loads(open(data_folder+'critDict3.txt').read())

Solution 1:

Your buttons have the same text attribute as the keys in your dictionary, which is very useful. When you declare a tkinter variable and link it to a widget, you can store it in the widget's .var attribute. Later, you can get the widget's text using widget.cget('text') to link the checkbutton and variable to each dictionary key.

defmakeUI(data_folder, critDict):
    top = Tk()
    checkbuttons = []
    for key, val in critDict.items():
        myVar = IntVar() # create intVar for this checkbutton
        key  = Checkbutton(top, text=key, variable=myVar) #create new checkbutton with text
        checkbuttons.append(key)
        key.var = myVar
        key.var.set(val[0])
        key.pack()
        T = Text(top, height=2, width=30)#create text box
        T.pack()
        T.insert(END, val[1])#fill text box with comments from dict
        text = T.get("1.0",'end-1c')#get text from text box


    button=Button(top, text="Update", command=lambda: save(critDict, checkbuttons))
    button.pack()

    top.mainloop()

Now if you want to access the variable associated with a dictionary key (and it's checkbutton), you can call key.var.get(), and then save the value to the appropriate dictionary key. Save could look something like this.

defsave(critDict, checkbuttons):
    for each in checkbutton:
        key = each.cget('text')
        critDict[key] = each.var.get()
