tkinter showing image in button - rwahdan - Jun-16-2021
Hi,
I am trying to show an image in a button. the approch is to read the path from a file and that path is in the last line. I am able to read the path from the file but i can't add it to the button. It gives error it can't find the path.
# find the last line for the photo
with open(username1, 'rb') as f:
f.seek(-2, os.SEEK_END)
while f.read(1) != b'\n':
f.seek(-2, os.SEEK_CUR)
last_line = f.readline().decode()
photo = PhotoImage(file=last_line)
photoimage = photo.subsample(1, 2)
Label(session_start, text="Welcome " + username1).pack()
Label(session_start, text="").pack()
Label(session_start, text="").pack()
Button(session_start, image=photoimage).pack(pady="150")Note:There was a new line break "\n" that I needed to take out. now I can see the space of the photo in the form but no image and yes i did pack()

Looks like there is a linefeed at the end of your filename.

I am new to programming with GUI. Do you mean extra line? I removed it and now no errors, just empty image box.

Try altering to the following code to keep a reference to the image otherwise the image can get garbage collected.
btn = Button(session_start, image=photoimage) btn.pack(pady="150") btn.photoimage = photoimage
