Creating a simple table cell in Qt
I want to create a simple table cell in Qt. So I wrote the following code
mainwindow.cpp
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QTableView>
#include <QSqlQueryModel>
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
ui->setupUi(this);
QTableView *view = new QTableView;
QStringListModel *model;
view->setModel(model);
view->show();
model->setHeaderData(0, Qt::Horizontal, QObject::tr("ID"));
model->setHeaderData(1, Qt::Horizontal, QObject::tr("Name"));
model->setHeaderData(2, Qt::Horizontal, QObject::tr("City"));
model->setHeaderData(3, Qt::Horizontal, QObject::tr("Country"));
}
MainWindow::~MainWindow()
{
delete ui;
}
main.cpp
#include <QtGui/QApplication>
#include "mainwindow.h"
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
mainwindow.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private:
Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H
But in the mainwindow.cpp file, I get the error "Model is not declared in this scope. Its inability to include the QSqlQueryModel header in the included part of mainwindow.cpp."
Can anyone point me to where I am doing wrong?
Thanks and Regards, Sid

I think you want a multidimensional table, but the QStringListModel is one dimensional, so you can try this code. I think it works the way you want, you get headers and you can set data in the model in the future
QTableView *view = new QTableView;
QStandardItemModel *mod = new QStandardItemModel;
QStandardItem *it = new QStandardItem(QObject::tr("ID"));
mod->setHorizontalHeaderItem(0,it);
QStandardItem *it1 = new QStandardItem(QObject::tr("Name"));
mod->setHorizontalHeaderItem(1,it1);
QStandardItem *it2 = new QStandardItem(QObject::tr("City"));
mod->setHorizontalHeaderItem(2,it2);
QStandardItem *it3 = new QStandardItem(QObject::tr("Country"));
mod->setHorizontalHeaderItem(3,it3);
//and so on
view->setModel(mod);
view->show();
About future. If you write QStandardItemModel * mod and after that write mod-> setHorizontalHeaderItem (), your program will crash because you are using a bad pointer. You must allocate memory before using
