New item not saved to combobox when added dynamically

[anda_skoa]

Your posting does not contain any code that would persist items in any way.

So if "when i closed the app and open the app" means you stop the program and run it again, then of course there won't be any data in the newly started instance of your program.

You can:
-write the data into a file using either QTextStream either QDataStream(on closing or when you add the item to the qcombobox) and when the QComboBox is loaded set it to read the file for content and add the saved content to your combobox
-use Sqlite in combination with QSqlDatabase,QSqlQuery to store and retrieve data from local database.
