Returning Tkinter Treeview iid

Question

I have a treeview and have inserted some data into it as shown below.

self.tree.insert('', 'end', iid="test1", text="test a", values=("data1", "data2"))

This adds an entry to the end of the treeview with text "test a" and column values of "data1" and "data2".

The iid has been set to "test1".

I would like to return the value of iid of an item in the treeview so that I can use it for some other function (I will be storing a file path in this iid)

I tried using treeview.item() and this returned the following dictionary without the iid:

{'version': 'data1', 'author': 'data2'}

(where version and author are the column headings)

So my question: is there a simple way to return the iid of a given row/entry to the treeview?

Answer 1

Learning Python, found no answer to this question here that I liked, so I finally figured out what I wanted and thought I would post what I found. iid = tree.focus() returns the information requested.

in my treeview i added this code:

for item in tree.selection():
    item_child = tree.get_children(item)
    item = tree.item(item)
    iid = tree.focus()
    print ("iid = ", iid, "Item = ", item, "Child iid's =", item_child)

this is my result from the code:

{'text': 'TRAINS', 'image': '', 'values': '', 'open': 0, 'tags': ['m']} iid = 1 Item = {'text': 'TRAINS', 'image': '', 'values': '', 'open': 0, 'tags': ['m']} Child iid's = ('8', '9', '10')

Notice at the beginning of line two of the result the iid is listed as "1" which is the correct iid for the item. All treeview items I select returned the correct iid.

Hope this helps the next person a little.

To get the iid you can use the identify() function:

tree.identify(event.x, event.y) # item at row "x" and column "y"

The iid argument stands for item identifier which is unique for each item, and you can give it the value you want.
