How to update

[unix7777]

I want an application using SQLite.I use QSQlqueryModel and QTableView to display the data.
I want when data (the model) changed to update the content displayed in the QTableView.
When i click on dialog i add new data to the model and when i click on the button ADD i want to close the dialog and on the widget behind to repaint/update the displayed data.

And the question is? All you have wrote is perfectly possible with a model and view approach.

The question is how to update TableView?I don't use MVC pattern!There should be some method for doing this.

QSqlQueryModel is read only: you cannot update the data through the model and the model has no way to know if the data underneath it has been changed externally. If you want to update the data through the model (using the table directly or a dialog that uses the model) then you want a QTableModel or similar. If you only want to refresh the read-only table because you know the underlying data has changed then call setQuery() again.
