Grey border around tkinter widgets (not using canvas)

Question

I am experiencing issues with a Python 3 tkinter program I'm working on.

I am running macOS Sierra.

When running the app, every widget has a grey border around it.

Is there any way to remove this?

Screenshot of the border:

Here's the code:

# Item list
itemlist=Treeview(root)
itemlist.heading("#0", text="Item Name")
itemlist["columns"]=("1")
itemlist.column("1",width=50)
itemlist.heading("1",text="Item ID")
itemlist.bind("<Double-1>", select)
itemlist.grid(row=2,column=1,padx=10,pady=10)

# Nametag
Label(root,text="Name:").grid(row=3,column=0)

# 'Save' Button
saveButton=Button(text="Save")
saveButton.bind("<Button-1>",savebind)
saveButton.grid(row=1,column=0)

# 'Add New' button
newItemButton=Button(text="New Event")
newItemButton.bind("<Button-1>",newItem)
newItemButton.grid(row=0,column=1)

# Name entry text field
itemNameEntry=Entry(root,width=25)
itemNameEntry.grid(row=3,column=1)

# Submit Button
submitButton=Button(root,width=25,text="Submit")
submitButton.grid(row=4,column=1)
submitButton.bind("<Button-1>",submit)

# Begin loading
load()

# Start GUI
root.mainloop()

set the actual background property of the widget to the same colour as your canvas background, its not a great fix but it works — WhatsThePoint, Feb 27 '17 at 11:43
That was already mentioned in an answer. Unfortunately, it doesn't work. — , Feb 27 '17 at 11:48
the answer mentioned `highlightbackground` try just `background` — WhatsThePoint, Feb 27 '17 at 11:55
Same result `_tkinter.TclError: unknown option "-background"` — , Feb 27 '17 at 12:01
I didn't use the dash. That's just the output of the error message. — , Feb 27 '17 at 13:17

Configure your widgets to use highlightbackground = 'white' (or whatever your background colour is) and set your highlightthickness=0

This should remove the grey outline.

EG

itemNameEntry=Entry(root,width=25, highlightbackground='white')
itemNameEntry.config(highlightthickness=0)

I get `_tkinter.TclError: unknown option "-highlightbackground"` and `_tkinter.TclError: unknown option "-highlightthickness"` when running. – Feb 27 '17 at 11:32
Unfortunately not :( – Feb 27 '17 at 11:47
looks like its a mac issue : http://stackoverflow.com/questions/27084321/tkinter-leaving-borders-around-widgets – Luke.py Feb 27 '17 at 11:53
I think they're separate, the colour looks different. – Feb 27 '17 at 11:57
you are comparing 2 different type of widgets there though? – Luke.py Feb 27 '17 at 12:01
Yes - but the colour is the same on all widgets in the program, including a button. – Feb 27 '17 at 12:02

You can use widget.config(highlightthickness=0) or pass this parameter in widget constructor.

If you are importing tkinter.ttk you need to import that first, then import tkinter.

from tkinter.ttk import *
from tkinter import *

This most likely doesn't fix the issue. – Expliked Feb 06 '21 at 23:39
