Tk treeview column sort

Question

Is there a way to sort the entries in a Tk Treeview by clicking the column? Surprisingly, I could not find any documentation/tutorial for this.

Answer 1

make this small change to the function if you have integers in your table it will look like this.

def treeview_sort_column(treeview: ttk.Treeview, col, reverse: bool):
    """
    to sort the table by column when clicking in column
    """
    try:
        data_list = [
            (int(treeview.set(k, col)), k) for k in treeview.get_children("")
        ]
    except Exception:
        data_list = [(treeview.set(k, col), k) for k in treeview.get_children("")]

    data_list.sort(reverse=reverse)

    # rearrange items in sorted positions
    for index, (val, k) in enumerate(data_list):
        treeview.move(k, "", index)

    # reverse sort next time
    treeview.heading(
        column=col,
        text=col,
        command=lambda _col=col: treeview_sort_column(
            treeview, _col, not reverse
        ),
    )
