That includes Button, Checkbutton, Radiobutton, and Message. For widgets without a textvariable parameter, update the display manually using .config(text=...)."}},{"@type":"Question","url":"https://www.askpython.com/python-modules/tkinter/stringvar-with-examples#faq-question-1783199200011","name":"Should I use a plain Python variable instead of StringVar?","acceptedAnswer":{"@type":"Answer","text":"Use a plain Python variable when you never link it to a widget and when you do not need to react to changes. Use StringVar when you need two-way binding between a widget and a variable, or when you want trace callbacks to fire on changes. For simple cases where you set a label once and never update it, a plain variable is less overhead."}},{"@type":"Question","url":"https://www.askpython.com/python-modules/tkinter/stringvar-with-examples#faq-question-1783199200012","name":"What happens if I pass a StringVar to two widgets?","acceptedAnswer":{"@type":"Answer","text":"Both widgets display the same value, and both update whenever the variable changes. This is useful for things like a header label and a status bar that always show the same message."}},{"@type":"Question","url":"https://www.askpython.com/python-modules/tkinter/stringvar-with-examples#faq-question-1783199200013","name":"Can I store non-string values in a StringVar?","acceptedAnswer":{"@type":"Answer","text":"You can pass an integer or float and Tkinter converts it to a string automatically. However, .get() always returns a string, so for numeric work you need to convert back with int() or float(). If you do that often, use IntVar or DoubleVar instead."}},{"@type":"Question","url":"https://www.askpython.com/python-modules/tkinter/stringvar-with-examples#faq-question-1783199200014","name":"How do I trigger code when StringVar changes?","acceptedAnswer":{"@type":"Answer","text":"Call .trace('w', callback) on the variable. The callback receives three arguments (name, index, mode) which is why *args appears in most examples. The callback runs synchronously whenever .set() is called or the linked widget is edited."}}]},{"@type":"Person","@id":"https://www.askpython.com/author/yogesh","name":"Yogesh Sharma","url":"https://www.askpython.com/author/yogesh","image":{"@type":"ImageObject","@id":"https://secure.gravatar.com/avatar/3ec076d6966fc4b867beb87bfff643a65b2e36aaf421ce300bd4d38ff86049ae?s=96&d=mm&r=g","url":"https://secure.gravatar.com/avatar/3ec076d6966fc4b867beb87bfff643a65b2e36aaf421ce300bd4d38ff86049ae?s=96&d=mm&r=g","caption":"Yogesh Sharma","inLanguage":"en-US"}},{"@type":"BlogPosting","headline":"Tkinter StringVar with Examples - Tkinter Tutorial - AskPython","keywords":"stringvar","datePublished":"2026-07-05T08:52:29+00:00","dateModified":"2026-07-05T10:56:00+00:00","author":{"@id":"https://www.askpython.com/author/yogesh","name":"Yogesh Sharma"},"publisher":{"@id":"https://www.askpython.com/#person"},"description":"StringVar is Tkinter's fix.
