Everytime I launch the code I get a blank tkinter window.
This had a few problems.
You had an _init_ method, not an __init__ method, so the created object wasn't being initialized.
You have to send the root tkinter object to the application, with app = ImprintPlusApp(root).
You had a self.header_frame once instead of self.frame_header.
You had a columnspan = 0 (which is invalid) instead of columnspan = 1 (which doesn't really need to be specified).
I've made the above changes in the code below. It may still need debugging, as I don't know exactly what design you had in mind.

I started working with tkinter recently and I have the following problem, I need to make the check box bigger but that is only possible with adding an image. The problem is that whenever I add an image to a button it becomes unclickable and the image is not displayed, here is my source code (part of a bigger project). My goal is to display some information and let the user decide which option he gets to keep using the check button. Any help is appreciated.

I tried some options that I saw on the forum, in another file they worked fine but when I tried to implement it in the project itself the checkbutton is still unclickable and it doesn't display the images either. tkinter checkbutton different image I tried to replicate Bryan's answer, but no luck there. Also didn't receive any console error message.
As #furas pointed in the comments above, the problem got fixed with keeping the images as member variables of the class, also the button became clickable after removing the self.toggle(var) command from checkbutton
the following is working first pass around. Select file/s, activate the view button and def, view files. all good.
When trying to select another file/s, during the selection process, the GUI closes abruptly.
I tried to figure out of the variable needs to be reset, but that did not change.
after all the imports:

this my situation. I'm learning how to use python (I just started) to create a GUI with Tkinter. One requirement of my application is to be able to store "DateEntry", while investigating I came across with tkcalendar DateEntry. The problem is that DateEntry is created as a class but my already created window(GUI) is a class as well and I don't know how to combine the class DateEntry into my class client which creates a mainwindow, I think that's beyond my knowledge. I want a DateEntry to be displayed in another toplevel() window when the button "Fecha Check-in" is used. Can anyone explain how to do it?
this is the image

You can use itertools.count() for that. It creates a generator, that just returns one number after the other, when you call it's next() method:
from itertools import count
counter = count(1)
for row in rows:
row_id = counter.next()
In this example on every iteration through the rows you will get an other value for row_id, starting from the given argument (which was 1): 1, 2, 3, …
Generators an also be used in for loops directly:
for number in count(1):
print(number)
This will fastly print a list of numbers.
In you class it would be a good idea to create the counter in __init__() and call next() when needed:
def __init__(self, master):
self.counter = count(1)
…(more code)…
def submit(self):
my_id = self.counter.next()
…(more code)…
Well, I've looked a lot in the web before asking, so here's the thing.
I'm not really experienced in Python and I need to develop this Matrix Generator. Yes, it is a mathematics matrix. I'm using Tkinter and Python 3.3.
First i ask the Number of Rows and Columns and then I fill each field and the code transforms it in a notepad for other programs to read.
I used the grid method so i'm having trouble with large scale matrices. The thing is I need to apply a scrollbar. I have read that I can use frame and a friend of mine showed me a scrollbar he made using frames. Can you help me? ;D
Every time I refer to linhas is the same as rows and colunas is the same as columns.
