HI i am trying to place the alignment of my Entry(Text Box) according to the image below. I tried everything, TOP BOTTOM LEFT RIGHT.
This is the alignment i want. Obtained from paint program*

The problem:
I am trying to update the same text widget box from a function that contains some text. Instead a whole new text window appears every time.
Here is my code:
from tkinter import *
import os
#Tkinter graphics
homepage = Tk()
homepage.title("My first GUI")
# set size of window
homepage.geometry('1200x400')
# Add image file
bg = PhotoImage(file = "maxresdefault.png")
# Show image using label
label1 = Label( homepage, image = bg)
label1.place(x = 0, y = 0)
label2 = Label( homepage, text = "Test App")
label2.pack()
# Create Frame
frame1 = Frame(homepage)
frame1.pack()
#button initatiors
def buttonupdate():
S = Scrollbar(homepage)
T = Text(homepage, height=100, width=30)
T.pack()
T.pack(side=RIGHT, fill= Y)
S.pack(side = RIGHT, fill = Y)
S.config(command=T.yview)
T.insert(END, "test")
T.config(yscrollcommand=S.set, state=DISABLED)
# Static buttons
tickets30button = Button(text = "This is button 1", command=buttonupdate)
tickets30button.place(x=0, y=26)
mcibutton = Button(text = "This is button 2")
mcibutton.place(x=0, y=52)
hdebutton = Button(text = "This is button 3")
hdebutton.place(x=0, y=78)
homepage.mainloop()
Here is the result if I click on the first button three times:
Let me know if you have any suggestions that I can try.
Thank you for your time,
I was able to update my text window instead of create a new one, upon each click of a button, thanks to #TheLizzard.
He mentioned to move the section of code that creates the text window outside of the function and keep the section of code that creates the text, inside the function.
Before:
#button initiators
def buttonupdate():
S = Scrollbar(homepage)
T = Text(homepage, height=100, width=30)
T.pack()
T.pack(side=RIGHT, fill= Y)
S.pack(side = RIGHT, fill = Y)
S.config(command=T.yview)
T.insert(END, "test")
T.config(yscrollcommand=S.set, state=DISABLED)
After: (UPDATED)
S = Scrollbar(homepage)
T = Text(homepage, height=100, width=30)
T.pack(side=RIGHT, fill= Y)
S.pack(side = RIGHT, fill = Y)
S.config(command=T.yview)
T.config(yscrollcommand=S.set, state=DISABLED)
#button initatiors
def myTicketstatusbutton():
T.delete(1.0,END)
T.insert(END, "test")
thanks a lot for your time. I'm currently stuck at the following point: I have developed a GUI with Tkinter with about 200 entries. (For simplification I have only included a small section below). But these 200 entries are seldom filled in at once. Normally 50 entries are filled in every start of the program. When the program is closed, these filled in values are deleted and have to be filled in again after the program is started again. Is there a way to prevent this?
I do not want to lose the values entered in jobNameA_entry and jobNameB_entry when closing the program.
Many thanks in any case.

I'm making some program, where I input a bunch of stuff into an entry and it gets printed into a row. I also added a feature where you can delete a row. However, when I delete a row, the window does not shrink. The way I actually made the program was by having 2 frames; the main frame with the buttons and entries, and the output or text frame. When I delete a row, it actually appends the data from a list, deletes the frame and all the widgets and reprints the rows, but with out the row I deleted.
The issue with my code, is that when I delete a row, the rows that weren't deleted start to get smaller and compress and secondly, the bottom of the window doesn't move upwards, leaving a blank white space.
Any help would be appreciated, thanks.
actually appending, labelling and printing the row is in function append_entry() and my delete function is delete_row()

Under the code
for widget in second_frame.winfo_children():
widget.destroy()
add this block of code
second_frame.pack()
it will be like this
for widget in second_frame.winfo_children():
widget.destroy()
second_frame.pack()
I hope this helps you
You can use
main_window.geometry("1200x800+100+100")
to change size and position of main_window. Here the window width will be 1200 and height will be 800, positioned 100px to the top left corner of screen. The +100+100 is optional.
You may add geometry() to delete_row callback to resize the frame. Though you might have to calculate the proper size after widget deletion.
As to "when I delete a row, the rows that weren't deleted start to get smaller and compress",
That's due to how grid layout works. If there are two widgets on the same grid row, the grid height will be equal the the higher widget height. When the higher widget is removed, the grid will resize to the smaller widget height and appear to 'shrink'.
To solve that, you can try add padding to the widget, the syntax is
widget.grid(column=1,row=1,padx=(10,10),pady=(10,10))
Alternatively, you may try other layout management: .place will give you absolute layout control. Or you can use pack and let tkinter decide the proper position.
This code is a part of my project in which I have to manage the attendance of 50 (or more) students.
The thing I want is that all the checkboxes should initially be 'checked' (showing the present state) and when I uncheck random checkboxes (to mark the absent) and click the Submit button (yet to be created at the bottom of the window), I should get a list with 'entered date' as first element and the roll numbers i.e. 2018-MC-XX as other elements.
For example: ['01/08/2020', '2018-MC-7', '2018-MC-11', '2018-MC-23', '2018-MC-44']
Actually my plan is when I will get a list I will easily write it to a text file. Also, if there is another way of creating multiple scrollable checkboxes without packing them inside a canvas then please do tell!
from tkinter import *
from tkcalendar import DateEntry
root = Tk()
root.geometry('920x600+270+50')
root.minsize(920,600)
Attendance_frame = Frame(root) ### Consider it a Main Frame
Attendance_frame.pack()
attendaceBox = LabelFrame(Attendance_frame, text = 'Take Attendance', bd = 4, relief = GROOVE, labelanchor = 'n',font = 'Arial 10 bold', fg = 'navy blue', width = 850, height = 525) # A Label Frame inside the main frame
attendaceBox.pack_propagate(0)
attendaceBox.pack(pady = 15)
dateFrame = Frame(attendaceBox) # A small frame to accommodate date entry label & entry box
dateFrame.pack(anchor = 'w')
font = 'TkDefaultFont 10 bold'
date_label = Label(dateFrame, text = 'Enter Date : ', font = font).grid(row = 0, column = 0, sticky = 'w', padx = 10, pady = 10)
date_entry = DateEntry(dateFrame, date_pattern = 'dd/mm/yyyy', showweeknumbers = FALSE, showothermonthdays = FALSE)
date_entry.grid(row = 0, column = 1, sticky = 'w')
noteLabel = Label(attendaceBox, text = 'Note: Uncheck the boxes for absentees').pack(anchor = 'w', padx = 10, pady = 5)
canvas = Canvas(attendaceBox, borderwidth=0, background="#ffffff")
checkFrame = Frame(canvas, width = 100, height = 50)
vsb = Scrollbar(canvas, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=vsb.set)
vsb.pack(side="right", fill="y")
canvas.pack(side="left", fill="both", expand=True)
canvas.pack_propagate(0)
canvas.create_window((4,4), window=checkFrame, anchor="nw")
def onFrameConfigure(canvas):
'''Reset the scroll region to encompass the inner frame'''
canvas.configure(scrollregion=canvas.bbox("all"))
checkFrame.bind("<Configure>", lambda event, canvas=canvas: onFrameConfigure(canvas))
for i in range(0,51): # A loop to create Labels of students roll numbers & names
c = Checkbutton(checkFrame, text = f"{'2018-MC-'+str(i+1)} Student {i+1}")
c.grid(row = i, column = 0, padx = 10, sticky = 'w')
mainloop()
First you need StringVar for each Checkbutton in order to get the state of the Checkbuttons later. Then you can use a list to hold the StringVars so that you can access them later. You can set the onvalue of the checkbuttons to the roll number associated to them.
Also you can use Text widget instead of Canvas+Frame. Below is an example:
import tkinter as tk
root = tk.Tk()
frame = tk.Frame(root)
frame.pack()
text = tk.Text(frame, width=40, height=20)
text.pack(side=tk.LEFT, fill=tk.BOTH)
vars = []
for i in range(51):
rollnum = '2018-MC-'+str(i+1)
var = tk.StringVar(value=rollnum)
cb = tk.Checkbutton(text, text=rollnum, variable=var, onvalue=rollnum, offvalue='', bg='white')
text.window_create('end', window=cb)
text.insert('end', '\n')
vars.append(var)
vsb = tk.Scrollbar(frame, orient=tk.VERTICAL, command=text.yview)
vsb.pack(side=tk.RIGHT, fill=tk.Y)
text.config(yscrollcommand=vsb.set)
def submit():
# extract roll numbers for checked checkbuttons
result = [var.get() for var in vars if var.get()]
print(result)
tk.Button(root, text='Submit', command=submit).pack()
root.mainloop()
I am currently working on a program where I need to change the position of a widget.
Here is my code:
root = Tk()
frame = Frame(root, bg="black")
label1 = Label(frame, text="not important")
label.grid(row=1, column=1)
#some stuff happens
x = aFunctionThatReturnsXCoordinate #not actual name
y = aFunctionThatReturnsYCoordinate
Now I want to change the position of label1 to the new coordinates.
I have tried:
label1.forget_grid()
label1.grid(rows=x, columns=y)
#Ive tried label1/frame.update after this code but it didnt do anything
I've also tried to do it without the grid_forget.
I didn't forget the frame.pack and root.mainloop.
Is there a function to change the position?
I have made a code which contains a label and a button. When the button is pressed , the row of the label changes from 0 to 1 and when pressed again row is changes from 1 to 0 and so on. To make difference between the frame and the root, I have set the color of the frame to sky blue and that of root to pink.
from tkinter import *
global rw;rw = 0
def changed():
global rw;rw += 1;
if rw == 2:rw=0
label.grid(row=rw,column=0)
root = Tk()
root.config(bg="pink")
frame = Frame(root, bg="sky blue")
frame.pack()
label = Label(frame,text="Hello")
label.grid(row=0,column=0)
b = Button(frame, text='Press me!', command=changed)
b.grid(row=0, column=1)
root.mainloop()
Well, the above code is a bit complicated so , if you want a simpler way to do the same:
from tkinter import *
def changed():
size = label.grid_info().get("row") #getting current row
if size == 0:size = 1
elif size == 1:size = 0
label.grid(row=size,column=0)
root = Tk()
root.config(bg="pink")
frame = Frame(root, bg="sky blue")
frame.pack()
label = Label(frame,text="Hello")
label.grid(row=0,column=0)
b = Button(frame, text='Press me!', command=changed)
b.grid(row=0, column=1)
root.mainloop()
Here is an animation:
Here is an example that toggles the position of a label from column 0 to column 1:
You have to keep in mind that unoccupied rows or columns are sized at zero pixels by the grid geometry manager.
pressing the button makes the label in row 1 swap places from column 0 to 1 and vice versa.
import tkinter as tk
def move_label(ndx=[0]):
# the 3 next toggle the column value
rowcol = [(1, 1), (1, 0)]
x, y = rowcol[ndx[0]]
ndx[0] = (ndx[0] + 1) % 2
label_at_1_0.grid(row=x, column=y)
root = tk.Tk()
frame = tk.Frame(root, bg="black")
frame.pack()
label_at_0_0 = tk.Label(frame, text="label_at_0_0")
label_at_0_0.grid(row=0, column=0)
label_at_0_1 = tk.Label(frame, text="not label_at_0_1")
label_at_0_1.grid(row=0, column=1)
label_at_1_0 = tk.Label(frame, text="label_at_1_0")
label_at_1_0.grid(row=1, column=0)
btn_to_move_label = tk.Button(frame, text='move label', command=move_label)
btn_to_move_label.grid(row=1, column=3)
root.mainloop()
