Refreshing QDataTable

[zlatko]

Hi all!
Can i refresh only changed records of QDataTable?

[jacek]

How would you find out whether the record was changed?

[zlatko]

I mean changing that user do own by editing some record in data table..

Ok i think my question has poor info for good understanding. I'll try correct that
So i have read only data table with 1000 records. For editing record i create new dialog, and after user press "Ok" i do dataTable->refresh(). I want refresh only some edited cell , but i see that my data table has full refresh The same thing hapend when i add or delete row..What i missed

Do you use QSqlSelectCursor with this QDataTable?

[zlatko]

yes..........

[jacek]

Well... you can't do this directly because QSqlSelectCursor is read-only, but QDataTable inherits QTable, so you could try to hack it using QTable methods or you can implement your own QSqlCursor subclass.

Another solution is to use QTable and fill it with data by hand.

Anyway, if your program uses a database, then probably more than one person will be using it at the same time. In such case you would want to refresh the data from time to time, so a refresh after adding a record won't be so bad (unless you have a really complex query).
