Without knowing what you have already tried it is possible that people will simply recommend things that have already caused you difficulty.

If you are using IDLE3, are you taking care to follow only tutorials that use Python3 as their scripting language? [Note, that is NOT the same thing as 'Python', which on the Raspbian OS will default to using Python Version 2.]

Which GUI toolkit do you hope to learn and use?

Also, since IDLE3 is itself a Python3 gui application I wonder if there might be conflicts if you try to use it to execute a script which itself tries to create a gui? [Using the Editor in IDLE3 should not be a problem - running the script might be. What happens if you run your script using something like python3 my_gui_script.py at a shell (terminal) prompt?]

I have found a very promising program called 'gui2py' - see https://code.google.com/gui2py/ . Although it says that it will run on Linux, most of the downloads appear to be for Windows, with a few Ubuntu files.

Any suggestions as to how to get this running on the RPi? I do not want to use this on my Windows machines as this rather defeats the object of programming on the RPi! I did try 'sudo apt-get install gui2py' but it did not want to know.

Any ideas?

BTW, your original link is not working!

I just tried some things i find on Google that would work. I've Done scripting work my knowledge on gui route programming is none. I want to attach my pi to my car run a auto start. Turn on and off kc lights lock unlock. Just trying to figure out how to make buttons to control gpio pins

from all the reading i have done tkinter should work on the idle 3 or the idle 2.7 and i tried both with no luck.. this is a copy of a button coding i had found and it will not work

Code: Select all

from Tkinter import *
 
import time
import RPi.GPIO as GPIO
 
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
GPIO.setup(18, GPIO.IN, pull_up_down=GPIO.PUD_UP)
 
def say_hi():
	print "Lighting up LED"
	GPIO.output(17, GPIO.HIGH)
	time.sleep(5)
	GPIO.output(17, GPIO.LOW)
	
def check_button():
	if (GPIO.input(18) == GPIO.LOW):
		labelText.set("Button Pressed.")
	else:
		labelText.set("")
	root.after(10,check_button)
 
root = Tk()
 
button = Button(root, text="Quit.", fg="red", command=quit)
button.pack(side=RIGHT, padx=10, pady=10, ipadx=10, ipady=10)
 
hi_there = Button(root, text="Light my LED!", command=say_hi)
hi_there.pack(side=LEFT, padx=10, pady=10, ipadx=10, ipady=10)
 
labelText = StringVar()
labelText.set("Button Pressed.")
label1 = Label(root, textvariable=labelText, height=4)
label1.pack(side=LEFT)
 
root.title("LED Blinker")
root.geometry('500x300+200+200')
 
root.after(10,check_button)
root.mainloop()

Hi,

I have written a few blog posts about using Tkinter. Once you get the hang of it it really is easy to churn out GUIs quite easily with it.

Have a look at this post as it may well help you.

Okay another question..... is there a way to make the file executable without having to run it through python?

[TrevorAppleton]

To make an .exe file so you don't have to use Python you could use py2exe.

...only problem is, tkinter is UGLY!

Why not make your own gui library with pygame..?

I don't have much knowledge I'm python didn't know that was possible. I will do some Looking into it and try and figure her out. Also found a good book on tkinter programming " tkinter gui applications and development" written by hotshot. For anyone who is looking for a book to read up on it

Hey where can I get a list of all the widgets for tkinter that are there for 2.7 python

I 'm in the middle of producing a set of tutorials on this exact topic in my series From Apple to Raspberry Pi which should give you a lot of what you are looking for, including examples. Head over to[ url]http://makeapppie.com/raspberry-pi/[/url] and look at the Tkinter section. I'll be covering stylized buttons and controls this week, and list boxes next week, but to get you some GUI buttons (including graphic ones) for now I think you will be able to get any simple button up and running.
