Add a "copy to clipboard" function for results

[hochwasser]

Hello,

it would be nice to copy the results from a query into the clipboard.
I made an attempt with the little knowledge of tk:
After defining the fw_Box with the result

fw_Box = Treeview(f2, columns=tree_columns, show="headings", padding=(2, 2, 2, 2))

attach a mouse handler that opens a popup menu

e = None

def cell_copy():
    global e
    citem = fw_Box.selection()[0]
    column = fw_Box.identify_column(e.x)
    column_no = int(column.replace("#", "")) - 1

    fw_Box.clipboard_clear()
    fw_Box.clipboard_append(fw_Box.item(citem)["values"][column_no])

def all_copy():
    # Kopf
    clipstr = "|"
    for col in fw_Box['columns']:
        clipstr += f"{col}|"
    clipstr += "\n"

    # Zeilen
    for line in fw_Box.get_children():
        clipstr += "|"
        for value in fw_Box.item(line)['values']:
            clipstr += f"{value}|"
        clipstr += "\n"

    fw_Box.clipboard_clear()
    fw_Box.clipboard_append(clipstr)

def popup_menu(event):
    global e
    e = event
    fw_Box.identify_row(event.y)
    popup1.post(event.x_root, event.y_root)

popup1 = Menu(fw_Box, tearoff=0)
popup1.add_command(
    command=cell_copy,
    label="Copy cell")
popup1.add_command(
    command=all_copy,
    label="Copy all")

fw_Box.bind('<Button-3>', popup_menu)

This code is more a prove of concept.
For example: I didn't figure out howto pass the variable event to the copy function.
