grid layout just not aligning perfectly, even when following lecturer's code-CodePudding

I'm learning python doing a udemy course so its watching pre-recorded videos. Following on recording laying out widgets on a screen (using tKinter) and just cannot get one button to align - even though I literally copy the code the lecturer has in the recording. I am sure I am missing something really simple here. Everything lines up except the "Generate Password" button which is off to the right. Its just a basic intro right now to GUI in Tkinter - so haven't gone into Frames as yet - just basic layouts.

Code is here - Everything aligns beautifully except the "Generate Password" button which shows up too far to the right - almost as if it is in another column...

from tkinter import *

def generate_pwd():
    pass

def add_pwd():
    pass
window = Tk()
window.title("Password Manager")
window.config(padx=50, pady=50)

# background canvas
canvas = Canvas(width=200, height=200)
img_lock = PhotoImage(file="logo.png")
canvas.create_image(100, 100, image=img_lock)
canvas.grid(column=1, row=0)

# widgets
lbl_website = Label(text="Website:")
lbl_website.grid(column=0, row=1, sticky=W)

lbl_email = Label(text="Email/UserName:")
lbl_email.grid(column=0, row=2, sticky=W)

lbl_password = Label(text="Password:")
lbl_password.grid(column=0, row=3, sticky=W)

ent_website = Entry(width=42)
ent_website.grid(column=1, row=1, columnspan=2, sticky=W)

ent_email = Entry(width=42)
ent_email.grid(column=1, row=2, columnspan=2, sticky=W)

ent_password = Entry(width=21)
ent_password.grid(column=1, row=3, sticky=W)

btn_generate = Button(text="Generate Password", command=generate_pwd)
btn_generate.grid(column=2, row=3)

btn_add = Button(text="ADD", width=35, command=add_pwd)
btn_add.grid(column=1, row=4, columnspan=2, sticky=W)


window.mainloop()

CodePudding user response：

From what I read, the width of a column is by default the width of its widest element; in your case, the culprit is the logo with its width of 100 that makes column 1 wider than it should be.

To fix this, just add a columnspan of 2 in your logo placement (in addition, the logo will be nicely centered):

...
canvas.create_image(100, 100, image=img_lock)
canvas.grid(column=1, row=0, columnspan=2)
