I need to change my keyboard on screen place but I dont know how to do anyone know it? code is :
def click(key):
if key == "<-":
entry2 = entry.get()
pos = entry2.find("")
pos2 = entry2[pos:]
entry.delete(pos2, tk.END)
elif key == " Space ":
entry.insert(tk.END, ' ')
else:
entry.insert(tk.END,key)
button_list = [
'q','w','e','r','t','y','u','i','o','p','<-',
'a','s','d','f','g','h','j','k','l',
'z','x','c','v','b','n','m'
,' Space '
]
r = 2
c = 0
for b in button_list:
rel = 'groove'
command = lambda x=b: click(x)
if b != " Space ":
tk.Button(pencere, text = b, width = 5, relief = rel, command = command).grid(row = r, column = c)
if b == " Space ":
tk.Button(pencere, text = b, width = 30, relief = rel, command = command).grid(row = 10, columnspan = 10)
c+=1
if c > 10 and r == 2:
c = 0
r+=1
if c > 8 and r == 3:
c = 0
r+=1
mainloop()
if anyone want I can send full code but I think you dont need more
Assuming your question is about placing your window on screen.
Solution
You can use the geometry() method to configure geometry of your window.
it takes a string in the format WxH±X±Y.
Reference
Geometry strings
Example
import tkinter as tk
root = tk.Tk()
root.geometry("300x300+100+100")
root.mainloop()

I couldnt seem to find a way to make my program realise that ive selected a button, so i changed the function of the celcius to farenheit to try to make it change a boolean value to determine what conversion the program is doing
def celcius_to_farenheit(_event = None):
c_to_f = True
f_to_c = False
the idea being later i can use if statments later in the end result function to find what conversion its doing and display results in the status bar
def end_result():
if c_to_f == True:
converted_temperature = (valid_temperature * 9/5) + 32
label_status.configure(text = converted_temperature, fg = "Orange")
currently i seem to have functions running without me pressing buttons as well, when start the program it immediatly goes to the error message ive created for input muct be numeric even if i havent pressed the celcius to farenheit button.
Any help regarding how to propely have my celcius to farenheit and farenheit to celcius buttons confirm its a float and change a value to use for determining which calculation its using would be helpfull. Knowing why the error message comes up automatically is a bonus.
Below is my code thank you for your time and help.

try:
valid_temperature = float(entry_temperature.get())
except:
label_status.configure(text = "Input must be numeric", fg = "Orange")
def end_result():
if c_to_f == True:
converted_temperature = (valid_temperature * 9/5) + 32
label_status.configure(text = converted_temperature, fg = "Orange")

I have used a loop to turn a list of 4 values into a set of buttons. I need to overwrite the text of these buttons to contain the values of another list (in this case Ans2). any help would be greatly appreciated.
import tkinter as tk
root = tk.Tk()
def NextQuestion():
print("this is where i need to configure the buttons to contain values from list - Ans2")
Ans1 = [6,5,32,7]
Ans2 = [4,9,3,75]
AnsNo = 0
r = 0
c = 0
for x in range(len(Ans1)):
AnsBtn = tk.Button(root, text=(Ans1[AnsNo]), command = NextQuestion)
AnsBtn.grid(row=r, column=c)
AnsNo = AnsNo+1
if r == 1:
c = 1
r = 0
else:
r = r+1
First you need to store the buttons somewhere so they can be accessed to be changed. Then you just access their text variable and change it.
import tkinter as tk
root = tk.Tk()
def NextQuestion():
for i, button in enumerate(buttons):
button["text"] = Ans2[i]
Ans1 = [6,5,32,7]
Ans2 = [4,9,3,75]
buttons = []
AnsNo = 0
r = 0
c = 0
for i,answer in enumerate(Ans1):
AnsBtn = tk.Button(root, text=(answer), command = NextQuestion)
AnsBtn.grid(row=r, column=c)
buttons.append(AnsBtn)
if r == 1:
c = 1
r = 0
else:
r = r+1
root.mainloop()
I am making a point of sale systems and one of the important things I'm trying to make is a total button or just a total. So when the total button is pressed, or every time an item is added, the total will be recalculated and outputted.
I started off with just declaring the variables:
item1_qty = 0
item2_qty = 0
item3_qty = 0
item4_qty = 0
item5_qty = 0
item6_qty= 0
item7_qty = 0
item8_qty = 0
item1_price = 0
item2_price = 0
item3_price = 0
item4_price = 0
item5_price = 0
item6_price = 0
item7_price = 0
item8_price = 0
itemTotal=0
and I'm using this code for the actual item buttons (I have 4 currently just so I don't get confused but I've included the first 2)
#Item1 Button + Function
def item1_Button():
global item1_qty
item1_text = ("Chips")
item1_price = "2.00"
item1_qty += 1
item1_text = (item1_text + " "+item1_price +" "+ str(item1_qty)) #concatonates text & variable
item1.config(text=item1_text) #updates label text - doesn't add multiple
item1.place(x=0, y=0) #places label within the frame
item1_Button = Button(itemFrame, text="Chips", width=10, height=10, command=item1_Button)
#creates button + links to function
item1_Button.grid(row=1, column=1) #positions button
item1 = Label(receiptFrame)#creates label for button
#Item2 Button + Function
def item2_Button():
global item2_qty
item2_text = "Fish & Chips"
item2_price = "5.00"
item2_qty += 1
item2_text = (item2_text + " "+item2_price +" "+ str(item2_qty)) #concatonates text & variable
item2.config(text=item2_text) #updates label text - doesn't add multiple
item2.place(x=0, y=50)
item2_Button = Button(itemFrame, text="Fish & Chips", width=10, height=10, command=item2_Button)
item2_Button.grid(row=1, column=2)
item2 = Label(receiptFrame)
I'm not entirely sure what I'm doing in terms of the actual total button, so I have kind of just started off with this:
def updateTotal():
global item1_price, item2_price, item3_price, item4_price
global item1_qty, item2_qty, item3_qty, item4_qty
itemPrice = item1_price + item2_price + item3_price + item4_price
itemQuantity = item1_qty + item2_qty + item3_qty + item4_qty
itemTotal = (itemPrice * itemQuantity)
totalPrice.config(text=str(itemTotal))
totalPrice = Label(totalFrame, font=("arial", 25), text="0"+str(itemTotal))
totalPrice.place(x=10, y=10)
totalButton = Button(totalFrame, text="Total", command=updateTotal, width=15, height=5)
totalButton.place(x=450, y=0)
Is there something I need to do different in terms of how I use the variables?
I would prefer if the total was just text that updated every time an Item button was clicked instead of a Total button but I would appreciate some guidance as nothing is happening at the moment and I'm not entirely sure what I need to do as I'm fairly new with tkinter.
You didnt provide a minimal reproducible example and this post is 2 months old so im not gonna really explain the code and it is mostly self explanatory.
used f-strings, they are like this:
intensifier = input("Enter an intensifier: ")
adjective = input("Enter an adjective: ")
sentence = f"This is {intensifier} {adjective}"
print(sentence)
The curly-brackets let you enter none string values and are automatically turned into a string. (Useable in most scenarios and no concatenation)
Changed items into lists, lists can be used like this:
list1 = ["value1",2,[value3]]
print(list1[0]) #Would print, "value1"
print(list1[1:2])#Would print, [2,[value3]]
Listbox is a box of lists, you can add stuff into it using
listbox.insert(<place to add to>, <object to add>)
Full Code:
from tkinter import *
root = Tk()
root.title("Receipt System")
items_qty = [0,0,0,0]
items_price = [2,5,0,0]
items_text = ["Chips","Fish&chips","",""]
global itemTotal #Global variable
items_total = [0,0,0,0]
currency = "£" #Sets currency
#Functions
def addItem(x):
items_qty[x] += 1 #Adds 1
totalPrice = items_qty[x] * items_price[x] #quantity * price
text = f"{items_qty[x]}x {items_text[x]} {currency}{totalPrice}"
for i in range(0, receipt.size()):
if items_text[x] in receipt.get(i):
receipt.delete(i)
receipt.insert(END, text)
updateTotal(x)
def updateTotal(x):
global items_total
items_total[x] = items_qty[x] * items_price[x] #quantity * price
total = 0
for i in range(0, len(items_total)):
total += items_total[i]
totalPrice.config(text=f"Total: {currency}{str(total)}")
#UI
itemFrame = Frame(root)
itemFrame.pack(pady = 10)
receiptFrame = Frame(root)
receiptFrame.pack(pady = 10)
item1Btn = Button(itemFrame, text=f"Chips - {currency}{items_price[0]}", command=lambda: addItem(0)).pack(side = LEFT, padx = 10)
item2Btn = Button(itemFrame, text=f"Fish & Chips - {currency}{items_price[1]}", command=lambda: addItem(1)).pack(side = LEFT, padx =10)

I'm trying to set an input to Combobox(values = output) from other
function (which connected to Button(command = some_function)
from tkinter import ttk
from tkinter import filedialog
from tkinter import *
def select():
global sel
a = ['101','102','103','104','105']
b = ['201','202','203','204','205']
sel = []
#label.configure(text = " Fleet" + fleet.get())
choosed = fleet.curselection()
for i in choosed:
selection = fleet.get(i)
print ("selected " + " " + selection)
if selection == 'B':
sel = b
else: sel = a
#print (sel)
return sel
root =Tk()
fleet = Listbox(root, width = 10, height = 2)
fleet.insert(1, 'B')
fleet.insert(2, 'A')
fleet.grid(column = 1, row = 0)
label = ttk.Label(root, text = "Please choose the fleet")
label.grid (column = 0, row = 0)
button1 = ttk.Button(root, text = 'Select', command = select)
button1.grid(column = 0, row = 1)
a = ['101','102','103','104','105']
b = ['201','202','203','204','205']
combo_tool_num = ttk.Combobox(root, width = 10, values = sel)
I would like to set an select() output sel, as an input for: combo_tool_num values = sel.
Thank you!
To set initial value in combobox use 'set()'
Use syntax as,
combo_tool_num = ttk.Combobox(root, width = 10, values = sel)
combo_tool_num.set('Select')
I've been making a script for checking grammar. Now I've updated it to be in a gui using Tkinter. The problem is that I'm trying to indicate the row where the grammar is wrong, and when I use an entry field to input the text everything is in one row.
My question is how do you expand the entry field?
This is my code:
import re
from tkinter import *
window = Tk()
window.minsize(width=300, height= 20)
wr = []
def work():
x = e1.get()
print(x)
BigLetterSearcher = re.compile(r'\. .|\n')
mo = BigLetterSearcher.findall(e1.get())
x = 1
y = 0
v = 0
z = ""
wr = []
for i in mo:
if i == '\n':
x += 1
elif i != i.upper():
v = 1
if x != y:
z = "Row", x
wr.append(z)
wr.append(i)
y = x
if v == 0:
wr.append ("Congratulations none of your grammar was wrong!")
l1.configure(text=wr)
l1 = Label(window, text="example")
e1 = Entry(window, text="Enter text here: ")
b1 = Button(window, text="Work", command=work)
leb = [l1, e1, b1]
for all in leb:
all.pack()
window.mainloop()
The entry widget is not capable of being expanded vertically. This is because there is already a widget designed for this and that is called Text(). For adding text to the text widget we can use insert() and you specify where with a 2 part index. The first part is the row and the 2nd is the column. For the row/line it starts at number 1 and for the index of that row it starts at zero.
For example if you wish to insert something at the very first row/column you would do insert("1.0", "some data here").
Here is you code with the use of Text() instead.
import re
from tkinter import *
window = Tk()
window.minsize(width=300, height= 20)
wr = []
def work():
x = e1.get("1.0", "end-1c")
print(x)
BigLetterSearcher = re.compile(r'\. .|\n')
mo = BigLetterSearcher.findall(x)
x = 1
y = 0
v = 0
z = ""
wr = []
for i in mo:
if i == '\n':
x += 1
elif i != i.upper():
v = 1
if x != y:
z = "Row", x
wr.append(z)
wr.append(i)
y = x
if v == 0:
wr.append ("Congratulations none of your grammar was wrong!")
l1.configure(text=wr)
l1 = Label(window, text="example")
e1 = Text(window, width=20, height=3)
e1.insert("end", "Enter text here: ")
b1 = Button(window, text="Work", command=work)
leb = [l1, e1, b1]
for all in leb:
all.pack()
window.mainloop()
Expanding an Entry field vertically can only be done by changing the size of the font associated with the Entry field...
e1 = Entry(window, text="Enter text here: ", font=('Ubuntu', 24))
results in a taller Entry field than
e1 = Entry(window, text="Enter text here: ", font=('Ubuntu', 12))
