On the widget is a ComboBox with data from the database. From this widget I invoke a dialog in which I make another entry to the database. How can I make this entry appear in my ComboBox, and not after restarting the program? If possible, in more detail, please.

- Can you give an example? I just do not understand how to connect this dialogue with the widget - Leonty Kopytov
- Connect to the
void QDialog::finished(int result)dialog completion signal (or send your own signal). In the handler, refill with the actual values of theQComboBox. - aleks.andr
