Python 3 tkinter on Raspberry Pi - python

Been fighting with this for too long wondered is someone might point me in the right direction. I am trying to establish an App that when triggered by a pir sensor attached to the rasberry pi opens a Frame with 7 buttons on it. I want the buttons when pressed to open separate frames in which i want to attach an image. I want the frame to disappear after a given time.
Now i can do this on the start page no problem creating a frame and canvas and loading an image in and then using after with destroy to get rid of it after 7 seconds.
However as soon as i try to bring other frames into the equation i cant seem to get canvases or images to work in the secondary frames. I changed my current approach which i set into clases (care of a tutorial on line) but dead end there as well.
Im not sure but i have the feeling that with classes i have now set up a master slave relationship with the frames meaning i cant customise them individually? I have attached the code im currently playing with that relates to the frames. If someone can advice be much appreciated.

Grid function in Tkinter not working when creating multiple pages

I am trying to use the grid function instead of the pack function in Tkinter so I can arrange my widgets better, however it is not working. I get this error message:
cannot use geometry manager pack inside .!frame.!startpage which already has slaves managed by grid
Any help would be appreciated. Scroll down to see where I have used grid, I have left a comment.

It already has slaves manages by grid, either use pack or grid but don't mix them up

How to display a function output/result in another window/frame using tkinter

i'm currently trying to creat a small accounting program where the user should type his earnings and expanses and the program should count it and display the differnt transactions in an secound frame. Im stuck at this point: So far ive created 6 frames where the user can switch between with buttons.
When the user click on the button "first transaction" he can entry a ammount and after he click on validate the ammount is displaying under the button.
But i want that the ammount is display at the frame "transaction overview"
After hours spending with searching the web i couln't find a way to display a functions output on a secound frame/window in the App. Thanks for your helf.

Tkinter navigation with frames

Hello,
I'm really stuck with this python code. Maybe you can help me?
I want to navigate pages with the buttons. I have three different frames. Then I press on one button, one frame goes on top of others, but do not hide other frames.
If my question for you isn't clear just try my code, and you will see what I mean.
This code from but little modified.

Thank you very much:)
You need to tell all the frames to use up all available space, so that they cover any frames below them. You do that by using the sticky argument:
frame.grid(row=0, column=0, sticky='nsew')
That tells the frame to stick to the north, south, east and west sides; in other words fill all the space in both directions.

Python Tkinter multiple frames with background image

I'm new to Tkinter and I'm struggling with what should be quite a simple bit of python code for my RasPi. My objective is to have a series of frames that all have the same fixed size and background image but have different buttons, labels (on top of the image) and functions. If I include a canvas and an image in the container then I can get my frames (well the first frame at least) to show the background image but I can't add anything to the canvas from the page specific class because I can't reference the canvas anymore?? If I leave the frames blank in the container then add the canvas/image in the page specific class then I can't get the canvas/image to work. This is the code that I'm trying to modify to suit my needs...
