[Tkinter] TKinter Remove Button Frame

[Nu2Python]

Hi All - How can I remove the button frame in my code? I have tried a few examples I found, but have had no luck. I see one argument example for 'borderwidth=0' but does not seem to change anything. I am using a toggle button with images. Attached picture is what I have showing for my button. The image has rounded corners, so I want to remove the frame of the button completely. Thanks for any help with this.

import tkinter as tk
from tkinter import *
from tkinter import messagebox
import requests
import http.client
import time
import json
   
path = ""

SONOFF_Temp  = 'http://192.168.0.130/cm?cmnd=status+10'
sonoff_url = 'NOT_INIT'


class RelayButton(tk.Button):
    """A button that toggles a relay"""
    def __init__(self, parent, url="", on_image=None, off_image=None, **kwargs):
        super().__init__(parent, image=off_image, command=self.toggle)
        self.url = url
        self._on = False
        self.on_image = on_image
        self.off_image = off_image
        self.label = Label(text="", bg="White", fg="Black", font=("Helvetica", 12))
        self.label.place(x=10,y=15)
        self.update_clock()
        self.templabel = Label(text="temp info", bg="White", fg="Black", font=("Helvetica", 12))
        self.templabel.place(x=10, y=40)

Setting borderwidth works fine for me. A pared down version of your code using some png files I have laying around:

import tkinter as tk

class RelayButton(tk.Button):
    def __init__(self, parent, on_image, off_image):
        self.images = {True: on_image, False: off_image}
        self.on = False
        super().__init__(
            parent,
            image=off_image,
            command=self.toggle,
            borderwidth=0,
        )

    def toggle(self):
        self.on = not self.on
        self["image"] = self.images[self.on]

app = tk.Tk()
RelayButton(
    app,
    tk.PhotoImage(file="games/ttt/o.png"),
    tk.PhotoImage(file="games/ttt/x.png"),
).pack(padx=100, pady=100)
app.mainloop()

I am assuming that the frame in your picture is not part of your image. You should verify that.

The little corners of your image outside the rounded button must also be the same background color as the main window, or you'll need to use RGBA images that have transparent backgrounds. I don't know if tkinter.PhotoImage handles transparency. You might have to use PIL to load an RGBA image. I don't normally bother with transparency in tkinter because all tkinter controls (like buttons) have an opaque background.

Maybe this will be of help...

I've had to do a very aggressive crop on your button image in order to make this work and it's not prefect.

import tkinter as tk
from tkinter.messagebox import showinfo

colour_theme = "#D2D2D2"

# root window
root = tk.Tk()
root.geometry('400x400')
root.resizable(False, False)
root.title('Image Button Demo')
root.config(
    bg=colour_theme
)


# button
def button_clicked():
    showinfo(
        title='Information',
        message='Button clicked!'
    )


icon = tk.PhotoImage(file='.assets/frPorch_off.png')
button = tk.Button(
    root,
    image=icon,
    command=button_clicked,
    activebackground=colour_theme,
    background=colour_theme,
    borderwidth=0,
    highlightbackground=colour_theme,
    width=207,
    height=207

)

button.pack(
    ipadx=5,
    ipady=5,
    expand=True
)


root.mainloop()

Thanks 'deanhystad' - I played around with this and seems to be working ok. I wish creating rounded corner buttons was easier, but when I looked into that it seems way to complicated to bother with. I am curious though about your mention of the RGBA images, I need to look into that.

rob101 - Thanks for your help as well, I need to play with this one also. Still learning a lot here with Python and Tkinter.

menator01 - thanks for the cropped image.

Appreciate all your time in helping me out.

You're welcome.

Tbh, I find that a GUI design app does much of the heavy lifting, allowing one to concentrate more on app functionality. I have made a few posts about that and what I use, but if you'd like me to link-up what I use, here, in your thread, then I'd be more than happy to do that.

rob101 - Thanks, that would be great actually. I am all for anything you want to share with me. There is plenty to learn for me in Python and I really enjoy the GUI stuff.

No worries.

Rather than reiterate what has already been said, I'll link to my post in the N&D Forum. I've also a couple of posts in the Code sharing Forum, for which I've used the PAGE GUI generator; they're easy to spot.
