The problem:
I would like to use this with an ESP32, to automate cli insructions. I have two buttons, the "Lets Go!!" button and the "Connect" button. "Connect" triggers def run which triggers def test and the command "rfq tty -P /dev/ttyUSB0", which will have some output displayed in the text box. I would like to use "Lets Go!!" to issue commands to that same thread/instance since it will be connected to the ESP32 with the "Connect" button.
Other:
I was able to adapt the terminal output found here (Redirect terminal output to tkinter). This is a work in progress, so the combo boxes don't trigger anything at this point. In the future I would like to .get() their values, and pass them as strings via the "Connect" button above.
Thank you for any help. Here is my code:

This works as tested with ping on both buttons. I am unsure if they are in the same instance though. I need to put together my esp32 setup to really test.

I have a gui with two tabs and would like to switch back and forth between the tabs while keeping the content of the tabs. If I do this all in one function, then it works fine, but since I have more in the individual functions. I have outsourced them. Now I have bound the individual functions to the tabs. But here I have the problem that I overwrite the tabs with every change. But I would like to switch between the tabs without overwriting the entries. I understand why I overwrite the input. After all, I call the individual functions with rountine and overwrite them that way. Unfortunately I do not know how to do it better.

All problem is that you use .gu1() and .gu2() in routine().
You should run .gu1() and .gu2() only once - at start in gui().
def gui(self):
# ... code ...
self.notebook.bind("<<NotebookTabChanged>>", self.routine)
self.gu1() # create at start
self.gu2() # create at start
def routine(self,event):
if self.notebook.index("current") == 1:
#self.gu1() # DON'T DO THIS
print('selected tab 1')
else:
#self.gu2() # DON'T DO THIS
print('selected tab 2')
Working code:
tkinter should use only one mainloop()
import tkinter as tk
from tkinter import ttk
class display():
def __init__(self):
self.root = tk.Tk()
self.root.geometry('400x300')

def routine(self,event):
if self.notebook.index("current") == 1:
#self.gu1() # DON'T DO THIS
print('selected tab 1')
else:
#self.gu2() # DON'T DO THIS
print('selected tab 2')
def gu1(self):
button1 = tk.Button(self.frame1, text="test1", command=self.changeText)
button1.grid(column=0, row=0)
self.label1 = tk.Label(self.frame1, text="test1")
self.label1.grid(column=1, row=0)
def gu2(self):
button2 = tk.Button(self.frame2, text="test2", command=self.changeText2)
button2.grid(column=0, row=0)
self.label2 = tk.Label(self.frame2, text="test2")

def changeText(self):
self.label1["text"] = "change1"
def changeText2(self):
self.label2["text"] = "change2"
if __name__ == "__main__":
display().gui()
EDIT:
If you have to create some widgets in tabs with delays (ie. to wait for user's values in other widgets) then you should use boolean variables (True/False) to run it only once in routine()
def gui(self):
# ... code ...
self.gu1_created = False
self.gu2_created = False
self.notebook.bind("<<NotebookTabChanged>>", self.routine)
def routine(self,event):
if self.notebook.index("current") == 1:
if not self.gu1_created:
self.gu1()
self.gu1_created = True
print('selected tab 1')
else:
if not self.gu2_created:
self.gu2()
self.gu2_created = True
print('selected tab 2')
This is to be a desktop application for opening multiple small databases and running queries on them. So far I've written some code for opening forms as necessary. Is this a good way to do it? Also - the code shown opens two copies of each form - what am I doing wrong? It's my first attempt at Python and I'm a rudimentary programmer so simple answers would be of most help please. TIA (Python 3.9.6)

As you can see in main window it is visible, but in sub window it is invisible.
And printing in console is correct:
I am trying to achieve grabbing par02_1 using .get(). I have success writing the rest of the .txt file but my program is not grabbing my gui entry lines. I'm guessing this has something to do with the association self, and the scrollable section, etc. but I can't track this one down. Any help is appreciated.

Hello thank you both for your guidance as I learn proper syntax. I have a long way to go but you both helped point me in the right direction so I can get my program online. I stripped this down to the basics and will implement a variation of the following architecture in my actual code.
from tkinter import *
from tkinter import ttk
import tkinter.messagebox
import time
root = Tk()
# GUI Window
root.title("Outfile Automation")
# Gui Future Menu Logic
def future01():

# GUI Main Menu
menu = Menu(root)
root.config(menu=menu)
subMenu = Menu(menu)
menu.add_cascade(label="File", menu=subMenu)
subMenu.add_command(label="New Script...", command=future01)
subMenu.add_separator()
subMenu.add_command(label="Exit Program", command=future01)
helpMenu = Menu(menu)
menu.add_cascade(label="Help", menu=helpMenu, command=future01)
helpMenu.add_command(label="Instruction Manual", command=future01)
helpMenu.add_command(label="Software Version: A0.003")
par02_1 = StringVar()
title_1 = Label(root, text="Device IP (DHCP)", fg="blue", font="Verdana 10 underline")
title_1.pack()
label_1 = Label(root, text="Device 01")
label_1.pack()
entry_1 = Entry(root, textvariable=par02_1)
entry_1.pack()
root.mainloop()
template = """[Script Header]\nDebugStrings=on\nAbortOnError=on\nConcurrentSectionLimit=230\n//23 Devices if necessary

I want to create a GUI program base on tkinter. One of the widgets is Text. I want to add a horizontal scrollbar in it, but it didn't work.
Where did I make a mistake?
from Tkinter import *
import tkFont
class DpWin(object):
def run(self):
root=Tk()
root.geometry('768x612')
title='dp'
root.title(title)
xscrollbar = Scrollbar(root, orient=HORIZONTAL)
xscrollbar.pack(side=BOTTOM, fill=X)
yscrollbar = Scrollbar(root)
yscrollbar.pack(side=RIGHT, fill=Y)
text = Text(root,xscrollcommand=xscrollbar.set,yscrollcommand=yscrollbar.set)
text.pack()
xscrollbar.config(command=text.xview)
yscrollbar.config(command=text.yview)
text.insert(END,'a'*999)
mainloop()
def start(self):
self.b_start.config(state=DISABLED)
self.b_stop.config(state=ACTIVE)
def stop(self):
self.b_stop.config(state=DISABLED)
self.b_start.config(state=ACTIVE)
if __name__=='__main__':
win=DpWin()
win.run()
I've modified your code according to here. There are 2 main differences.
I made it so the textbox doesn't wrap. If you wrap text, there is nothing for the horizontal scrollbar to scroll to.
I used the grid geometry manager on a frame to keep the scrollbars and text widgets together. The advantage to using .grid is that you actually get scrollbars which are the correct width/height (something you can't achieve with pack).
...
from Tkinter import *
import tkFont
class DpWin(object):
def run(self):
root=Tk()
root.geometry('768x612')
title='dp'
root.title(title)
f = Frame(root)
f.pack()
xscrollbar = Scrollbar(f, orient=HORIZONTAL)
xscrollbar.grid(row=1, column=0, sticky=N+S+E+W)
yscrollbar = Scrollbar(f)
yscrollbar.grid(row=0, column=1, sticky=N+S+E+W)
text = Text(f, wrap=NONE,
xscrollcommand=xscrollbar.set,
yscrollcommand=yscrollbar.set)
text.grid(row=0, column=0)
xscrollbar.config(command=text.xview)
yscrollbar.config(command=text.yview)
text.insert(END, 'a'*999)
mainloop()
def start(self):
self.b_start.config(state=DISABLED)
self.b_stop.config(state=ACTIVE)
def stop(self):
self.b_stop.config(state=DISABLED)
self.b_start.config(state=ACTIVE)
if __name__=='__main__':
win=DpWin()
win.run()
There is one comment regarding making both x and y scrollbars work within the pack framework. Here is a minimal example:
import tkinter as tk
from tkinter import X, Y, BOTTOM, RIGHT, LEFT, Y, HORIZONTAL
class TextExample(tk.Frame):
def __init__(self, master=None):
super().__init__()
sy = tk.Scrollbar(self)
sx = tk.Scrollbar(self, orient=HORIZONTAL)
editor = tk.Text(self, height=500, width=300, wrap='none')
sx.pack(side=BOTTOM, fill=X)
sy.pack(side=RIGHT, fill=Y)
editor.pack(side=LEFT, fill=Y)
sy.config(command=editor.yview)
sx.config(command=editor.xview)
self.pack()
def main():
root = tk.Tk()
root.geometry("800x500+0+0")
app = TextExample(master=root)
root.mainloop()
if __name__ == '__main__':
main()
