QDataWidgetmapper

[locus]

Thanks for your attention wysota. This what i have tried to do so far:

x::x(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
	setupUi(this);
 
 
 
	QSqlTableModel *model = new QSqlTableModel(this);
   model->setTable("user_info");
 
 
 
	QDataWidgetMapper *mapper = new QDataWidgetMapper(this);
	mapper->setModel(model);
 
mapper->addMapping(spinBox, 0);
	mapper->addMapping(lineEdit, 1);
	mapper->addMapping(lineEdit_2, 2);
	mapper->addMapping(spinBox_2, 3);
	mapper->toFirst();

x::x(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
	setupUi(this);


	
	QSqlTableModel *model = new QSqlTableModel(this);
   model->setTable("user_info");

	 
	
	QDataWidgetMapper *mapper = new QDataWidgetMapper(this);
	mapper->setModel(model);

mapper->addMapping(spinBox, 0);
	mapper->addMapping(lineEdit, 1);
	mapper->addMapping(lineEdit_2, 2);
	mapper->addMapping(spinBox_2, 3);
	mapper->toFirst();

Class "x" inherits a form that i created. This form was created in designer with the editors (lineEdit, lineEdit_2,ect) that were mapped to "mapper".

The code above is the constructor for class "x". Below is the declaration for class "x".

#ifndef X_H
#define X_H
 
#include <QtGui/QMainWindow>
#include "ui_x.h"
 
class x : public QMainWindow,public Ui_xClass
{
    Q_OBJECT
 
public:
    x(QWidget *parent = 0, Qt::WFlags flags = 0);
    ~x();
 
 
};

#ifndef X_H
#define X_H

#include <QtGui/QMainWindow>
#include "ui_x.h"

class x : public QMainWindow,public Ui_xClass
{
    Q_OBJECT

public:
    x(QWidget *parent = 0, Qt::WFlags flags = 0);
    ~x();


};

This was simply an attempt to get QDatawidgetmapper to work as explained in the docs, but i would really like to use it in my project.

my connections to the database were done in main, and works fine as i tested it by assigning the model to a QTableView, and the information came up. Nothing comes up in the widgets that were mapped though.
