I'm trying to create a recipe display which will show the step, instructions, weight and other variables on a screen in a Tkinter GUI.
However, I do not know how to update the GUI to change with each new step of the recipe, as the content has to be dynamically updated based on user input (taken from a server). How can I achieve updating of the GUI's other elements based on the change in steps?
You can use
after() to run function after (for example) 1000 miliseconds (1 second) to do something and update text on labels. This function can run itself after 1000 miliseconds again (and again).
It is example with current time
from Tkinter import * import datetime root = Tk() lab = Label(root) lab.pack() def clock(): time = datetime.datetime.now().strftime("Time: %H:%M:%S") lab.config(text=time) #lab['text'] = time root.after(1000, clock) # run itself again after 1000 ms # run first time clock() root.mainloop()
BTW: you could use
StringVar as sundar nataraj Сундар suggested
Using .config() to Update Widgets, from Tkinter import * import time #Tkinter stuff class App(object): def __init__(self) : self.root = Tk() self.labeltitle = Label(root, text="", fg="black", font="Helvetica 40� Understand the Tkinter code. Create frames, labels, buttons, binding functions, events and all. To develop simple GUI apps. So next up on this Tkinter Tutorial blog, we’re going to create a simple Calculator GUI with all the stuff that we’ve learned till now.
if you want to change label dynamically
self.dynamiclabel=StringVar() self.labeltitle = Label(root, text=self.dynamiclabel, fg="black", font="Helvetica 40 underline bold") self.dyanamiclabel.set("this label updates upon change") self.labeltitle.pack()
when ever you get new value then just use
self.dyanamiclabel.set("Hurrray! i got changed")
this apply to all the labels.To know more read this docs
How to update the gui in a loop without blocking the , In this video I'll show you how to use .config() to update just about after this tkinter Duration: 8:00 Posted: Apr 28, 2020 Create a GUI in Python using tkinter.

If you are using labels, then you can use this:
label = tk.Label(self.frame, bg="green", text="something") label.place(rely=0, relx=0.05, relwidth=0.9, relheight=0.15) refresh = tk.Button(frame, bg="white", text="Refreshbutton",command=change_text) refresh.pack(rely=0, relx=0.05, relwidth=0.9, relheight=0.15) def change_text() label["text"] = "something else"
Works fine for me, but it is dependent on the need of a button press.

Labels in Tkinter (GUI Programming), I have a Raspberry pi and using Python I've wrote a GUI to control a fan using PWM and to work out the RPM from the fans pulsed output.
