changing order of items in tkinter listbox

listbox, python, tkinter, user-interface, widget

Solution

Is there an easier way to change the order of items in a tkinter listbox than deleting the values for specific key, then re-entering new info?

No. Deleting and re-inserting is the only way. If you just want to move a single item up by one you can do it with only one delete and insert, though.

def move_up(self, pos):
    """ Moves the item at position pos up by one """

    if pos == 0:
        return

    text = self.fileListSorted.get(pos)
    self.fileListSorted.delete(pos)
    self.fileListSorted.insert(pos-1, text)

Problem

Is there an easier way to change the order of items in a tkinter listbox than deleting the values for specific key, then re-entering new info? For example, I want to be able to re-arrange items in a listbox. If I want to swap the position of two, this is what I've done. It works, but I just want to see if there's a quicker way to do this. ``` def moveup(self,selection): value1 = int(selection[0]) - 1 #value to be moved down one position value2 = selection #value to be moved up one position nameAbove = self.fileListSorted.get(value1) #name to be moved down nameBelow = self.fileListSorted.get(value2) #name to be moved up self.fileListSorted.delete(value1,value1) self.fileListSorted.insert(value1,nameBelow) self.fileListSorted.delete(value2,value2) self.fileListSorted.insert(value2,nameAbove) ```
