retrieve text inside QLineEdit inside QTableWidget

Lightshadown

Hi, im trying to get the data displayed in a QTableWidget, everything comes from a database and some calculations to the data itself, everytime i want to retrieve the data from a cell using the follow code, my program wont compile with the follow error error: use of deleted function 'QLineEdit::QLineEdit(const QLineEdit&) the table was made with Qt Designer

QLineEdit a = widget_PP.Registros_General->cellWidget(1,1)->findChild<QLineEdit>();

as far as i know the cellwidget retrieves the data inside the qwidget, i also used a qobject_cast but i got a similar error

QLineEdit a = qobject_cast<QLineEdit>(widget_PP.Registros_General->cellWidget(0,0));

i need the information display on the QTableWidget so i can send it to my printer, any idea where i might be wrong? i did try using item(), but that wont work because im using a QlineEdit

Read the docs carefully! Both findChild<QLineEdit>(); and cellWidget(0,0) will return a pointer to the widget. Your code is written for returning the widget itself, which is the cause of the error messages:

QLineEdit *a = widget_PP.Registros_General->cellWidget(1,1)->findChild<QLineEdit>();
QLineEdit *a = qobject_cast<QLineEdit *>(widget_PP.Registros_General->cellWidget(0,0));

Of course these will only find such a QLineEdit if you have previously gone setCellWidget().

@JonB i did follow your advice and used the pointer, my error was the lack of the pointer and now its working properly, thanks
working code:

QLineEdit *a = widget_PP.Registros_General->cellWidget(1,1)->findChild<QLineEdit*>(); // this works

QLineEdit *a = qobject_cast<QLineEdit*>(widget_PP.Registros_General->cellWidget(1,1))  // doing object cast works as well
