QDataTable to bloquer modified value

[cristiano]

People, I have a QDataTable, I would like that when a value of the QDataTable was modified, the user I could not more modify, these values I am white.

Here he is form.

In the case above, if the user modified value e if it tried to modify an error message again would be shown. It would like to make this for the application and not for the database.

It is possible to block this with the QDataTable.

You can override one of the protected members of QDataTable to deny an edit if data was already modified.

I would like to make something thus.

if ((HCO!="") || (HCO is NULL)) {
msg="Error";
}

My answer still stands - it should be possible to do that by overriding updateCurrent() or beginUpdate().

Ok, more I get error trying to use QDataTable::updateCurrent

dataTable->updateCurrent()

dataTable->updateCurrent()

I didn't tell you to call the method but to override it. You have to subclass QDataTable and reimplement the method.
