hplip 3.14.10, no python-devel

Question

I am experimenting with tkinter in python.

At the moment I have created a script which creates a login window which has no function what so ever. I have tried playing around with the def callback(): and command=callback. So I tried making it so that when you press the "Login" button, you can do something (e.g. show loading... and clear text boxes.)

Here is the code:

import tkinter

window = tkinter.Tk()
window.title("Login")
window.geometry("250x150")
window.configure(background="#FFFFFF")

label = tkinter.Label(window, text="Please Login to continue:", bg="#FFFFFF", font=("PibotoLt", 16))
label.pack()
label = tkinter.Label(window, text="username:", bg="#FFFFFF")
label.pack()
entry = tkinter.Entry(window)
entry.pack()
label = tkinter.Label(window, text="password:", bg="#FFFFFF")
label.pack()
entry = tkinter.Entry(window)
entry.pack()

def callback():
    button = tkinter.Button(window, text="Login", fg="#FFFFFF", bg="#000000")
    button.pack()
    label = tkinter.Label(window, text="Loading...", bg="#FFFFFF", command=callback)

window.mainloop()

Solution

This answer suggests quite a long list of dependencies you have to install before running the script, but I got the same error as you and simply did sudo apt-get install python-dev, then re-ran the script.

It's installed now and I can see my HP OfficeJet Pro 8620 printer.

no one has an idea on how to fix the problem

So the question is - how to make a button?Also, please format the code with the code markdown

Move this .Label(..., command=callback to the .Button(..., command=callback and add a ` print('Hello World)'` to your def callback():.

I tried to clarify the code but I'm not 100% I got the indentation right.

sudo apt-get install python-dev worked for me on Debian 8.6 64bits
