tab widget with two entries

[acmezger]

Yes, thats what I did, however for many double entries this is quite a work. I hoped it would be easier
Thanks

You could write such widget with help of two QTabBars and a QStackedWidget, here is a working example for it.

#include <QtGui>
#include <QApplication>
 
class DoubleTabWidget : public QWidget
{
    Q_OBJECT
 
public:
    explicit DoubleTabWidget(DoubleTabWidget * parent = 0)
        : QWidget(parent)
        , row(0)
        , col(0)
        , hTabBar(new QTabBar)
        , vTabBar(new QTabBar)
        , viewPort(new QStackedWidget)
    {
        QGridLayout * gridLayout = new QGridLayout(this);
 
        gridLayout->addWidget(hTabBar,  0, 1, 1, 1);
        gridLayout->addWidget(vTabBar,  1, 0, 1, 1);
        gridLayout->addWidget(viewPort, 1, 1, 1, 1);
 
        hTabBar->setShape(QTabBar::RoundedNorth);
        vTabBar->setShape(QTabBar::RoundedWest);
 
        connect(vTabBar, SIGNAL(currentChanged(int)), SLOT(setRow(int)));
        connect(hTabBar, SIGNAL(currentChanged(int)), SLOT(setCol(int)));
 
        addSampleWidget();
    }
 
private slots:
    void setRow(int r)
    {
        row = r;
        updateWidget();
    }
 
    void setCol(int c)
    {
        col = c;
        updateWidget();
    }
 
private:
    int       row;
    int       col;
    QTabBar * hTabBar;
    QTabBar * vTabBar;
    QStackedWidget * viewPort;
    QList<QList<QWidget *> > widgets;
 
    void updateWidget(void)
    {
        if(col < widgets.count())
            if(row < widgets.at(col).count())
                viewPort->setCurrentWidget(widgets.at(col).at(row));
    }
 
    QWidget * createWidget(int r, int c)
    {
        const QString name = QString("QWidget (%1, %2)").arg(r).arg(c);
 
        QWidget * widget = new QGroupBox;
        QGridLayout * gridLayout = new QGridLayout;
        QWidget * label = new QLabel(name);
        gridLayout->addWidget(label);
        gridLayout->setAlignment(label, Qt::AlignCenter);
        widget->setLayout(gridLayout);
        return widget;
    }
 
    void addSampleWidget(void)
    {
        QList<QWidget *> wids;
 
        for(int i = 0; i < 5; i++)
            hTabBar->addTab(QString("Widget %1").arg(i));
 
        for(int j = 0; j < 5; j++)
            vTabBar->addTab(QString("Widget %1").arg(j));
 
        for(int i = 0; i < 5; i++)
        {
            wids.clear();
            for(int j = 0; j < 5; j++)
            {

                wids.append(widget);
                viewPort->addWidget(widget);
            }
            widgets.append(wids);
        }
    }
};
 
int main(int argc, char *argv[])

    tabWidget.show();
 
    return app.exec();
