Search information on QTableView

[Mihan]

Hi all

I want to make a function about searching on QTableView with QSqlQueryModel.

I think it is too cumbersome that if I use QSqlQuery to research the information from database.
And I have used QCompleter and connect the model so that I can input the key words Conveniently.

what should I do next?

Best regards
Mihan

BTW, if I insert data by the other QSqlQuery, does the QSqlQueryModel know that and refresh the data automatically?

No

You can e.g. iterate over the model's data and search for the things you want.

I find QSortFilterProxyModel, maybe it can do what I want(searching).

OTOH, how to refresh the data from QSqlquerymodel when the database was inserted new data?

What about using the same QSqlQuery? QSqlQueryModel set the same QSqlQuery and I use the same QSqlQuery to insert data.

This proxy is for filtering and sorting. Don't see why you need this for searching - the search functionality is the same as in it's base class QAbstractItemModel.

By using QSqlTableModel and doing the modifications through the model
