    Recently, some of our readers have told us that they have encountered a tkinter bind memory leak.



    I dynamically have a meaningful table with a fixed row selection (like a FIFO queue) that is constantly being updated using the tkinter after () function. Inside the table there is a button, text that can be edited.

    To make the button text editable, I used BrenBarn’s current solution and bound the current loop variable in the functional email to the command attribute.

    While going through the update_content_items () process, I noticed that the memory usage in MB is increasing by MB per second. I can also confirm that after commenting out this lambda expression, the memory leak disappeared. (as seen from the terminal live, like “above”)

  • Looks like I am using a lambda, otherwise I would say the button has the wrong directory and the user is editing the wrong line when I just used self.list_items [i] even if the user just clicked. Yes

    is there a way to solve the problem? How can a user right click and change it, having the correct directory and getting rid of a particular leak?

Please get the edit_barcode function.") 

    EDIT: There seems to be a deeper memory leak (Python itself) for sure. Images are not produced with garbage. Is memory slow in Python 3.x and am I using PIL? Again: loading is picturedit is usually not fixed by issuing a name memory leak

    What can I do because I need to iterate over the numbers with records and update the labels on the images? Is there a job? PhotoImage does not have an explicit close () function, and even if I call del, the link is created by the GC and no configuration with the label is possible.
