Tkinter Entry Widget .get Doesn't Work

I am fairly new to python and am currently working on a school project, my aim is to create a search bar that can be used to search a data file, however I am struggling to get the

Solution 1:

Your code lacks a call to mainloop(). You could try adding it to the end of the drawStatWindow() function:

statWindow.mainloop()

You might want to restructure your code into a class. This allows you to avoid using global variables and generally provides better organisation for your application:

from tkinter import *

class App:
    def __init__(self, statWindow):
        statWindow.title("View Statistics")
        statWindow.config(bg = "grey")
        statWindow.geometry('800x900')

        self.searched = StringVar()
        searchBox = Entry(statWindow, textvariable=self.searched)
        searchBox.place(x= 450, y=50, width = 200, height = 24)
        enterButton = Button(statWindow, text ="Enter", command=self.searchButton)
        enterButton.config(height = 1, width = 4)
        enterButton.place(x=652, y=50)

    def searchButton(self):
        text = self.searched.get()
        print(text)


root = Tk()
app = App(root)
root.mainloop()

Solution 2:

You have to add mainloop() because tkinter needs it to run.

If you run code in IDLE which use tkinter then IDLE runs own mainloop() and code can work but normally you have to add mainloop() at the end.

And you have to remove tkinter in tkinter.Button.

from tkinter import *

def searchButton():
    text = searched.get()
    print(text)

def drawStatWindow():
    global searched

    statWindow = Tk()
    statWindow.title("View Statistics")
    statWindow.config(bg="grey")
    statWindow.geometry('800x900')

    searched = StringVar()

    searchBox = Entry(statWindow, textvariable=searched)
    searchBox.place(x= 450, y=50, width=200, height=24)

    # remove `tkinter` in `tkinter.Button`
    enterButton = Button(statWindow, text="Enter", command=searchButton)
    enterButton.config(height=1, width=4)
    enterButton.place(x=652, y=50)

    # add `mainloop()`
    statWindow.mainloop()

drawStatWindow()

Solution 3:

No need to use textvariable, you should use this:

searchBox = Entry(statWindow)
searchBox.focus_set()
searchBox.place(x= 450, y=50, width = 200, height = 24)

then you will be able to use searchBox.get(), that will be a string.
