[Bug] Hitting the image-count limit [Fail to create pixmap with Tk_GetPixmap in TkImgPhotoInstanceSetSize] about pysimplegui HOT 6 CLOSED

I just verified that 200.000 text elements work without a problem (albeit a bit slow to load)

That makes it even more weird that it crashes before even 5000 empty image elements.

Also this means i can pivot to using ✅ and ❎ as emoji's in text in the meantime.

Alright, i worked around the bug but i'm still leaving the issue open since i'm curious if there is a fix, i might run into it in the future.

This is a tkinter-based error, not a PySimpleGUI one. It would be helpful to write a small example using tkinter and report it to that team. I certainly am not going to know about any values deep in tkinter.

Rather than brute force creating so much at one time in RAM, can you think of a bit more sophisticated design that can get around this (perhaps reasonable) limitation? You can't show 200,000 images all at the same time, so some kind of buffering, paging, etc, scheme should be possible.

Hey!

I think you are right about it being a good idea to add pagination.
Maybe baking the stuff in an image with pillow is an option too, but i also have tooltips on every item.

In the future i could make a fake scrollbar on 1 axis that loads and deloads stuff.

Also i tested out if tkinter breaks at high image counts and the breaking point is really similar, it's a tiny bit higher on tkinter alone.
And PySimpleGUI with 200.000 text objects still breaks if it's mixed in with columns and similar.

So it looks like it's just a general memory limit issue in tkinter where the image objects take a ton of space compared to other types.

I'm going to experiment further and might report my issues to tkinter/wx/Qt etc if i get around to it.

But anyways thanks for the response!

thanks for the response!

Sure! That's why we're here. Thank you for the "thanks"!

Jason's posted several examples of various ways of implementing loading of assets as needed rather than creating them in advance in response to user's issues over the years. You should be able to locate some by searching the issue database (assuming you can craft a search that returns a reasonable number of hits).

Maybe you can refer issue #3787
