QTableWidget

Hi,
First, let me explain, I am an old timer coder, but have never dealt with QT.

My question is:
I created a QTableWidget using the gui creator (.ui) I then want to load data
into the 2 dim. array.

I attempted associated the slot "on_tablewidget_activated" and used
tableWidget->setItem to load the data, but when debugging, it never
enters the function on_tablewidget_activated.

How do I load data into the TableWidget?

Snippet of code:

Code:

---

********************************
.h file:
 
class Widget : public QWidget {
    Q_OBJECT
public:
    Widget(QWidget *parent = 0);
    QTableWidget tableWidget(QWidget *parent = 0);
    ~Widget();
 
protected:
    void changeEvent(QEvent *e);
 
private:
    Ui::Widget *ui;
 
private slots:
    void on_tableWidget_activated(QModelIndex index);
 
*******************************************
 
.cpp file
#include "widget.h"
#include "ui_widget.h"
 
Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);
}
 
Widget::~Widget()
{
    delete ui;
}
 
void Widget::changeEvent(QEvent *e)
{
    QWidget::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        ui->retranslateUi(this);
        break;
    default:
        break;
    }
}
 
void Widget::on_tableWidget_activated(QModelIndex index)
{
    QTableWidgetItem *item = new QTableWidgetItem(QString("testing"));
    tableWidget->setItem(1,1,item);
 
}

thanks

Are you sure you want to use the activated() signal?
The slot will be called when you activate the item which has the index 'index', which is not what I think you want.
Just loading data to the table can be done via a normal method call (for example in the constructor).

Hi,
Thanks for the info. I tried moving it to the constructor and am getting the following syntax error. Can you see what I am doing wrong?

/home/john/qt/projects/perf1/widget.cpp:10: error: invalid use of member (did you forget the ‘&’ ?)

h file:

Code:

---

#include <QModelIndex>
#include <QTableWidget>
 
namespace Ui {
    class Widget;
}
 
class Widget : public QWidget {
    Q_OBJECT
public:
    Widget(QWidget *parent = 0);
    QTableWidget *tableWidget(QWidget *parent = 0);
    ~Widget();
 
protected:
    void changeEvent(QEvent *e);
 
private:
    Ui::Widget *ui;
 
private slots:
    void on_tableWidget_activated(QModelIndex index);
};
 
#endif // WIDGET_H
 
c file:
#include "widget.h"
#include "ui_widget.h"
 
Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);
    QTableWidgetItem *item = new QTableWidgetItem(QString("testing"));
    tableWidget->setItem(1,1,item);
}

you probably meant

Code:

---

tableWidget()->setItem(1,1,item);

thanks. that did the trick.

it was one of those "I can't see the forest through the trees"
