Or create a SQL query that does this instead of just SELECT *. That is going to be much faster than a proxy model. Bo.

Hi all, I am a newbie in QT, and I have difficulties in using QThreads. What occurs is that i created one class named Logger what functions like a stream to a log file.

[Interest] Default delegate with QTableView and QSqlTableModel
Hi all, I have a QTableView and a connected QSqlTableModel. The database is an SQLite database with two columns, the types are TEXT and INTEGER. Everything is works as expected, except I don't get QSpinbox as a editor for the INTEGER column, so I can write there anything, and since the SQLite can store TEXT in an INTEGER column, I don't even get an error... So what can I do? Can I set the type (QVarinat::Int) of the column somehow (in the model or in the view)? If I use setItemDelegateForColumn on the view manually, can I use a ready made delegate somehow or the only possible solution is to create a SpinBoxDelegate for myself?

No, you're just falling into a very common error when using \b. \b matches the 0-length transition between a \w character and a \W, and the beginning and the end of the string are counted as a \W. But there's no such transition in your string: the \b is between the beginning (\W) and the leading backslash (\W again). Therefore, it will not match.
