Use QLineEdit with mask AND validator for money OUTPUT
-
I created a dialog containing some QLineEdits and a QTableView.
The QLineEdits are connected to a QTableView using QDataWidgetMapper, so, whenever I select a row in QTableView, QLineEdits are filled with their respective values (see below).
One column in the QTableView is CURRENCY type, but it is not showing correctly the value.For example, the value 1234.50 should be presented in format "1.234,50" (because I'm using Brazilian Real), however, the QLineEdit presents in the format "1234.5", removing the zero and not exchange point by comma.
I'm using setValidator (as specified below), but this works only when I edit the content of the QLineEdit, not when the values are showed.
Please, how can I solve this problem? Thank you for your help everyone.

ui->leditPreco->setValidator(new QRegExpValidator(preco, ui->leditPreco));

// Populate the table and put in first record.

I'm not sure what do you mean. Which format the data you're trying to set has? An integer / a double you need to format in a specific way? ( Qt 4.8 will introduce QLocale support for currencies (f.i. QLocale::toCurrencyString). )

It is a double. But someone suggested to me subclass QValidator to validate what is introduced in the lineedit. I did this and it worked.
Thank you!
