在角落中加载Tkinter中的图像

Question

I'm beginner in Python and Tkinter. I'm trying to put an image in the top-left corner but I couldn't. I was tried with the property "justify" and "Anchor". Here is my code:

logo_upb = PhotoImage(file="upb.gif")
label = Label(root, image=logo_upb, justify=LEFT)
label.image = logo_upb
label.place(bordermode=INSIDE, x=0, y=0)
label.pack()

I would be thankful with any solution.

Answer 1

Have you tried grid geometry manager.

The grid geometry manager puts the widgets in a 2-dimensional table. You'll be surprised how much easier it is to use the grid manager instead of packer.

Lets take this example to show what grid can do. Creating this layout using the pack manager is possible, but it takes a number of extra frame widgets.

But with grid geometry manager you can also have the widgets span more than one cell. The columnspan option is used to let a widget span more than one column < checkbutton > and < image >, and the rowspan option lets it span more than one row < image >.

The following code creates the shown layout:

label1.grid(sticky=E)
label2.grid(sticky=E)

entry1.grid(row=0, column=1)
entry2.grid(row=1, column=1)

checkbutton.grid(columnspan=2, sticky=W)

image.grid(row=0, column=2, columnspan=2, rowspan=2,
           sticky=W+E+N+S, padx=5, pady=5)

button1.grid(row=2, column=2)
button2.grid(row=2, column=3)

So your answer will be identical to position of < label 1 > in other words grid would be row = 0 , and column = 1 . Tkinter has native support for GIFs, so there is no need for additional library.

import Tkinter as tk

root = tk.Tk()
img = tk.PhotoImage(file ="somefile.gif")
panel = tk.Label(root, image = img)
panel.grid(row=0,column=1)
root.mainloop()

My personal recommendation is using Python Imaging Library (PIL) link: http://www.pythonware.com/products/pil/ adding more supported files formats to the game. List of supported files formats: http://infohost.nmt.edu/tcc/help/pubs/pil/formats.html

In this example I used .jpg file format which is not natively supported in tkinter, and all works perfectly because we are using PIL.

import Tkinter as tk
from PIL import ImageTk,Image

root = tk.Tk()
img = ImageTk.PhotoImage(Image.open("somefile.jpg"))
panel = tk.Label(root, image = img)
panel.grid(row=0,column=1)
root.mainloop()

Warning: Never mix grid and pack in the same master window. Tkinter will happily spend the rest of your lifetime trying to negotiate a solution that both managers are happy with. Instead of waiting, kill the application, and take another look at your code. A common mistake is to use the wrong parent for some of the widgets.

Answer 2

The specific reason for your problem is that you use place more-or-less correctly, then throw all that placement away when you call pack() . place , pack and grid aren't complimentary -- you must use only one to manage any particular widget.
