QTableWidget

[martial_arts_drummer]

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:

********************************
.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

John

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:

#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

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

thanks. that did the trick.

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