Tkinter Spinbox Widget Setting Default Value
Tkinter Spinbox is used to add the increment and decrement buttons to the Entry widget, making it useful to handle the numerical data of any application. A spinbox widget can be created using the Spinbox(arguments). We can set the default value for the spinbox widget by defining the Value using StringVar() object. The default value plays a vital role for any widget, as it helps you to define the bounded value.
Example
#Import Tkinter library from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame or window win= Tk() #Set the geometry of tkinter frame win.geometry("750x250") #Set the default value for SpinBox my_var= StringVar(win) my_var.set("1.0") #Create a spinbox spinbox= ttk.Spinbox(win, from_=0.5, to=10.0, increment=0.01, textvariable=my_var) spinbox.pack(ipadx=20, pady=20) win.mainloop()
Output
Executing the above code will display a window that contains a spinbox having a default value set to 1.0.
