How to get all row information from Treeview widget in Tkinter

问题

I want to write a command for a button that will take all of the information from ALL of the rows (except the title row) in my treeview widget and then later paste it onto a label or preferably a listbox. I don't know how to reference the rows of this widget to pass the info from them especially since my widget can have any number of rows depending on the invoice for that customer. Any help is greatly appreciated.
