![]() tv.item() method is used to provide new values to the record.sal_up variable holds the calculation to increment the salary.by using temp, temp, temp we can access the items in the tuple.These values will be displayed in a tuple format. This means from the selected row, show all the values. tv.item() takes 2 arguments, selected & values.You can view that by using the print function. tv.focus() hold the row number of the selected item in Treeview & the value for the same is stored in a variable named selected.In this code, please pay attention to the update_item function. We will understand this with an example wherein the salary of the selected employee will be incremented by 5% of the current.This will return all the values in the selected item. () takes as an argument followed by ‘ value‘.If nothing is selected then it returns an empty string (“”). returns the selected item row in the Treeview.In this section, we will be changing only one item of the record.To change the value of the record, we have to create a function that will change the value of the selected item in the Python Tkinter Treeview.Tv.heading('Badge', text='Badge', anchor=CENTER) Tv.heading('Name', text='rank', anchor=CENTER) Tv.heading('Rank', text='Id', anchor=CENTER) Tv.column('Badge', anchor=CENTER, width=80) Tv.column('Name', anchor=CENTER, width=80) ![]() Tv.column('Rank', anchor=CENTER, width=80) Let us see the Python tkinter treeview example. …where the blue arrow is the data deleted after to be selected and now it seems to print the options for the function that I used while the red arrow shows that the data in the column is automatically affected (‘a’ is the last letter of a name… it was automatically deleted after deleting the row showed by the blue arrow, leaving only the last letter of it and I can’t understand why it does).Read Login page in Python Tkinter with database SQLite3 Python Tkinter Treeview Example Ins_tv = tv.insert("", 0, values=(cogn, nom, nasc)) So, here is the point: from tkinter import * Now, I guess to be quiet next to the solution but it still messing me. I need to return on this topic because I didn’t solved yet… ![]() So, how can I get the windows upgraded from the selection deleted in the treeview windows to rewrite the file? Tv.insert("", 0, values=(cogn, nom, nasc)) ![]() With open('/path/to/file.csv', 'r+') as elenco: With open('/path/to/file.csv', 'w') as elenco: ![]() Message="Si vuole confermare l'eliminazione permanente di") I tried a lot of times to rewrite the file without the data that I don’t need but I can’t understand how to get the infos from the treeview after deleting from it. I also tried to put the treeview’s content in the csv.writerow method but I saw that is not possible.įor sure (as always) it would be a very silly thing to do but I can’t approach to this. Items between parenthesis are referred to a csv.reader method that print the results in a tkinter’s treeview with the ’ insert ’ method. Scr_el_csv.writerow([canc_info, nome, nascita, Scr_el_csv = csv.writer(elenco_aggiornato) Values = tuple(tree_em(selezione))Ĭanc_info = tree_lete(selezione) My function rewrite the whole file, erasing everything from it or I also obtained a copy of the whole file but with a repeated line that is not my choice.Īfter the code just posted above, my last attempt was: def elimina(): I tried different combinations but I can’t understand the way to rewrite the file without the line I chose to delete. ![]()
