Guizero textbox focus

I am a newb and I have a small script that uses guizero to create a small app that reads a rfid tag and activates door lock. The problem I am having is, when the power goes off and the raspberry pi reboots. the script launches but I have to manually click in the texts box before it will start working. how can I have it automatically set focus on the textbox when it launches?
thanks
Mark
Here is code, I found this project online and modified some to work for me.
from gpiozero import LED, Buzzer
from guizero import App, Box, Text, TextBox, warn
import gpiozero
import csv
RELAY_PIN = 17
led8 = LED(5)
led9 = LED(6)
relay= gpiozero.OutputDevice(RELAY_PIN,active_high=False, initial_value=False)
def clearDisplay():
print("Clear display")
rfidStatus.value = "—"
rfidText.value = ""
led8.off()
led9.off()
relay.off()
rfidStatus.repeat(1000, checkRFidTag)
def checkRFidTag():
tagId = rfidText.value
if tagId != "":
RFidRegistered = False
print(tagId)
with open("Database.csv") as csvfile:
reader = csv.DictReader(csvfile)
for row in reader:
if row["RFid"] == tagId:
RFidRegistered = True
print("Welcome " + row["User"])
rfidStatus.value = "Welcome " + row["User"]
led8.on()
relay.toggle()
rfidStatus.after(5000, clearDisplay)
if RFidRegistered == False:
print("RFid tag is not registered")
rfidStatus.value = "RFid tag is not registered"
led9.on()
rfidStatus.after(3000, clearDisplay)
rfidStatus.cancel(checkRFidTag)
app = App(title="RFID EM4100 Simple GUI", width=350, height=150, layout="auto")
instructionText = Text(app, text="Click on the text button below\nand scan your RFid tag.")
rfidText = TextBox(app,text="")
rfidStatus = Text(app, text="—")
rfidStatus.repeat(1000, checkRFidTag)
#designBy = Text(app, text="Design by Idris – Cytron Technologies", align="bottom")
app.display()
view

You could use a timer associated with the app to call a fuction shortly after starting up. For example, use:
app.after(1000,setFocus)
to call:
def setFocus():
nameOfTextBox.focus()
The example below sets up two text boxes and two buttons. By commenting out one or other of the lines in setFocus it sets focus to the right hand text box or the cancel button after one second:
from guizero import App, Text, Box, TextBox, PushButton
import sys
app = App(title="Give Focus")
app.width = 500
app.height = 100
paddingHeight = 1
paddingWidth = 10
buttonWidth = 10
topBoxHeight = 100
bottomBoxHeight = 100
app.height = topBoxHeight + bottomBoxHeight
def setFocus():
rightTextBox.focus()
# buttonCancel.focus()
def call_exit():
buttonCancel.text="Exiting"
buttonCancel.enabled=False
app.update()
app.destroy()
sys.exit()
topBox = Box(app, align="top", width= "fill", height = topBoxHeight, border= True)
textFieldBox = Box(topBox, align="top", width= "fill", height= "fill", border= True, layout = "grid")
paddingT00 = Text(textFieldBox, text="", width = paddingWidth, height = paddingHeight, grid = [0,0])
paddingT10 = Text(textFieldBox, text="", width = paddingWidth, height = paddingHeight, grid = [1,0])
message = Text(textFieldBox, text="Text Field Box", grid = [2,0])
paddingT01 = Text(textFieldBox, text="", width = paddingWidth, height = paddingHeight, grid = [0,1])
leftTextBox = TextBox(textFieldBox, text="Type here", width = paddingWidth, height = 1, grid = [1,1])
paddingT21 = Text(textFieldBox, text="", width = paddingWidth, height = paddingHeight, grid = [2,1])
rightTextBox = TextBox(textFieldBox, text="...or here", width = paddingWidth, height = 1, grid = [3,1])
bottomBox = Box(app, align="top", width= "fill", height = bottomBoxHeight, border= True)
buttonBox = Box(bottomBox, align="top", width= "fill", height= "fill", border= True, layout = "grid")
paddingB00 = Text(buttonBox, text="", width = paddingWidth, height = paddingHeight, grid = [0,0])
paddingB10 = Text(buttonBox, text="", width = paddingWidth, height = paddingHeight, grid = [1,0])
message = Text(buttonBox, text="Button Box", grid = [2,0])
paddingB01 = Text(buttonBox, text="", width = paddingWidth, height = paddingHeight, grid = [0,1])
buttonOK = PushButton(buttonBox, text="OK", width = paddingWidth, height = 1, grid = [1,1])
paddingB21 = Text(buttonBox, text="", width = paddingWidth, height = paddingHeight, grid = [2,1])
buttonCancel = PushButton(buttonBox, text="Cancel", command = call_exit, width = paddingWidth, height = 1, grid = [3,1])
app.after(1000,setFocus)
app.display()

create a scrollbar on entry with cavnas, python tkinter

I'm trying to put a scrollbar on entry that created on canvas..
I've tried this code
from tkinter import *
root = Tk()
root.geometry('400x600')
root.resizable(0,0)
page = Canvas(root, width=400, height=600, bd=0, highlightthickness=0,scrollregion=(0,0,500,500))
MyImage1 = PhotoImage(file='Study With4.png')
CanvasImage = page.create_image(0,0,image= MyImage1, anchor='nw')
entry =Text(page,height=29,width =46,wrap=WORD,bg='#F8F8F8')
scroll = Scrollbar(entry, orient=VERTICAL)
scroll.pack(side=RIGHT, fill=Y)
scroll.config(command=page.yview)
page.config(yscrollcommand=scroll.set)
page.create_window(200,285, window=entry)
page.pack()
mainloop()
but it doesn't work and I don't know where is the problem.

I've made minimal changes to your code, the biggest is creating a Frame called "label"
to contain Text and Scrollbar then inserting that into Canvas window.
Your scroll object was not defined properly with confusion around page and entry objects.
from tkinter import *
root = Tk()
root.geometry('500x600')
root.resizable(0,0)
page = Canvas(
root, width = 500, height = 600, bd = 0,
highlightthickness = 0,scrollregion = (0,0,1000,1000))
page.pack(side = LEFT, fill = BOTH, expand = True)
MyImage1 = PhotoImage(file='Study With4.png')
CanvasImage = page.create_image(0, 0, image = MyImage1, anchor = NW)
label = Frame(root)
label.pack(fill = BOTH, expand = True)
entry = Text(label, height = 29, width = 46, wrap = NONE, bg = '#F8F8F8')
entry.pack(side = LEFT, fill = BOTH, expand = True)
scroll = Scrollbar(label, orient = VERTICAL)
scroll.pack(side=RIGHT, fill=Y)
scroll.config(command = entry.yview)
entry.config(yscrollcommand = scroll.set)
page.pack()
page.create_window(25, 25, window = label, anchor = NW)
mainloop()

Hey guys, I'm having an issue with my tkinter gui program.
When i call the addItem function, instead of creating a new label every time, it just replaces the current one. Any help would be much appreciated!

You made a Label named self.item and you keep overwriting it, expecting it to magically be a new Label. The fix is simple ~ don't create self.item. Create a list instead and push new Labels onto it as they are needed. This sets the stage for your delete method, as well ~ as you can just unpack everything in the cache, delete the desired item and repack whatever is left in the cache. My example is commented where it counts. I didn't write a delete method for you.
import tkinter as tk
root = tk.Tk()
root.title("To Do")
root.geometry("500x750")
root.resizable(False, False)
class App:
def __init__(self, window):
#Button font
self.buttonFont = ("Courier", 13, "normal")
#Header
self.header = tk.Label(text = "To Do List\n", font = ("Helvetica", 26, "bold"))
self.header.grid()
#Add item button
self.addButton = tk.Button(text = "Add Item", font = self.buttonFont, bg = "green", command = self.OpenAddItem)
self.addButton.grid(row = 1, column = 0, )
#Del item button
self.delButton = tk.Button(text = "Delete Item", font = self.buttonFont, bg = "red")
self.delButton.grid(row = 1, column = 1, )
#items frame and stuff
self.itemsframe = tk.Frame()
self.itemsframe.grid(row = 2)
''' you just keep overwriting this '''
#self.item = tk.Label(self.itemsframe, font = ("Helvetica", 11, "normal"))
#start a cache instead
self.items = []
def OpenAddItem(self):
#COnfiguring prompt win
self.addPromptWin = tk.Toplevel(root)
self.addPromptWin.title("Prompt")
self.addPromptWin.geometry("375x100")
self.addPromptWin.resizable(False,False)
#Entry label
self.entryLabel = tk.Label(self.addPromptWin,text = "Enter item name:", font = ("Courier", 11, "normal"))
self.entryLabel.grid(sticky = tk.E)
#Adding entry
self.entry = tk.Entry(self.addPromptWin, font = ("Courier", 11, "normal"))
self.entry.grid(row = 0, column = 1)
self.entry.bind("<Return>", lambda e: self.AddItem())
#Add new item button
self.addNewItemButton = tk.Button(self.addPromptWin, text = "Add", font = self.buttonFont, bg = "green", command = self.AddItem)
self.addNewItemButton.grid(row = 1, sticky = tk.W)
def AddItem(self):
self.entryValue = self.entry.get()
'''
you can keep configuring and repacking this for infinity
it's not going to change the fact that it's the same label every time
'''
#self.item.config(text = f"1. {self.entryValue}")
#self.item.pack()
#append a new label to the cache instead
self.items.append(tk.Label(self.itemsframe, font = ("Helvetica", 11, "normal"), anchor='w'))
#config and pack the last item in the cache

Cannot make that scroll bar shows frame untill the bottom

I am trying to create a pop up help window for a tool. I managed to add the scrollbar to a frame that contains canvas and label widget. However that Scrollbar does not shows the img_canvas_3 that I added.
Here is my code:
from tkinter import *
import tkinter.filedialog
from tkinter.filedialog import askopenfilename
from tkinter.filedialog import askdirectory
import PIL
from PIL import Image, ImageTk
help_window = tkinter.Tk()
help_window.title("Help")
help_window.geometry("400x800")
#frame.grid(row=0,column=0)
canvas=Canvas(help_window,bg='red',width=300,height=800,scrollregion=(0,0,500,500))
scroll_y = Scrollbar(help_window, orient="vertical", command = canvas.yview)
frame=Frame(canvas,width=300,height=800, bg="green")
description_label = Label(frame, text = "\n\tMy Tool\n",anchor = "w").pack(side = TOP, fill = "both")
introduction = "This tool provides a basic workflow"
introduction_text = Label(frame, text = introduction, anchor = "w", font = "Verdana 10", bg="yellow").pack(fill = "both")
label_1 = Label(frame, text = "Input Data 1", anchor = "w", font = "Verdana 10", justify=CENTER).pack(fill = "both")
img_canvas_1 = Canvas(frame, bg = "black", height = 300, width = 300)
img_canvas_1.pack(side = TOP)
label_2 = Label(frame, text = "Input Data 2", anchor = "w", font = "Verdana 10", justify = CENTER).pack(fill = "both")
img_canvas_2 = Canvas(frame, bg = "black", height = 300, width = 300)
img_canvas_2.pack(side = TOP)
label_3 = Label(frame, text = "Input Data 3", anchor = "w", font = "Verdana 10", justify = CENTER).pack(fill = "both")
img_canvas_3 = Canvas(frame, bg = "black", height = 300, width = 300)
img_canvas_3.pack(side = TOP)
canvas.create_window(0, 0, anchor = 'nw', window = frame)
canvas.update_idletasks
canvas.configure(scrollregion=canvas.bbox('all'),
yscrollcommand = scroll_y.set)
canvas.pack(fill = 'both', expand = TRUE, side = 'left')
scroll_y.pack(fill = 'y', side = 'right')
help_window.mainloop()
I expected to have the scroll bar working, basically showing all the widgets and elements in the frame as I am adding more and more. That is only true for the untill img_canvas_2
Does anyone have an idea why this is not the case with my code? I tried by playing around with the scrollregion parameter in the canvas variable, but it did not work.
Thanks in advance.

OptionMenu in tkinter keeps crashing when placed in a frame

I am trying to place an OptionMenu widget inside of a frame, which itself is inside of a notebook. From what I've found online, the code for doing this is roughly:
# add a drop down menu
hops = range(0,6)
self.selectedHop = StringVar(frame2)
self.selectedHop.set(hops[0])
self.hopOptions = OptionMenu(frame2, self.selectedHop, *hops)
self.hopOptions.grid(row=0, column=2, sticky=EW)
However, when I place this in my code in the code below (the chunk above is placed towards the bottom of it, and is labeled "PROBLEMATIC CODE..."), my app just freezes and I have to force quit it, and I have no error message to debug with. Any help would be appreciated.

This is your problem. You're packing a LabelFrame in frame2, and then trying to grid something in frame2. A given container can only use one of grid() or pack()- using both won't cause an error, but the two managers will negotiate on how to place things for the rest of your lifetime.
The solution is to make sure that a given container's children are either packed or gridded, but never both in the same container (though you could have a structure parent->child->grandchild, where child is packed in parent and grandchild is gridded in child).
