This tutorial will show how to create a Dropdown menu feature using the Tkinter Library. The Tkinter library is used to create GUIs and various different elements and Dialog Windows.
To create a dropdown menu the Tkinter widget OptionMenu will be used.
This program will use an OptionMenu to let user selected size. If the “Print ” button is clicked it will print out the selected Size. When the user selects a size, the selected sizes will be given a 1 and the unselected sizes a 0
from tkinter import *
SIZES = ['Small','Med.','Large','XL']
#Get Selected Sizes
def print_SIZES(*args):
values = [(Size, var.get()) for Size, var in data.items()]
values
print(values)
data = {} # dictionary to store all the IntVars
#tkinter option menu
TKINTER = Tk()
TKINTER.title("Size Selector")
bMenu= Menubutton ( TKINTER, text="Select Size ", relief=RAISED )
bMenu.menu = Menu ( bMenu, tearoff = 0 )
bMenu["menu"] = bMenu.menu
#if selected
for Size in SIZES:
var = IntVar()
bMenu.menu.add_checkbutton(label=Size, variable=var)
data[Size] = var # add IntVar to the dictionary
btn = Button(TKINTER, text="Print", command=print_SIZES)
btn.pack()
bMenu.pack()
TKINTER.mainloop()
Output:
[('Small', 0), ('Med.', 1), ('Large', 1), ('XL', 0)]
