Problem with QTreeWidget after subclassing

[steve918]

I'm having trouble adding QTreeItems to a QTreeWidget after subclassing it. The following code works fine, but no items appear in the treewidget.


xtreewidget.h

#include <QTreeWidget>
 
class xTreeWidget: public QTreeWidget {
    Q_OBJECT
    public:
        xTreeWidget(QWidget *parent);
        void redraw();
    public slots:
    private:
};

#include <QTreeWidget>

class xTreeWidget: public QTreeWidget {
    Q_OBJECT
    public:
        xTreeWidget(QWidget *parent);
        void redraw();
    public slots:
    private:
};

To copy to clipboard, switch view to plain text mode 

xtreewidget.cpp

xTreeWidget::xTreeWidget(QWidget *parent) {
    redraw();
}
void xTreeWidget::redraw() {
    //Doesn't Work
    QTreeWidgetItem *item1 = new QTreeWidgetItem(this);
    item1->setText(0,tr("item1"));
    //This don't either.
    QTreeWidgetItem *item2 = new QTreeWidgetItem;
    addTopLevelItem(item2);
    item2->setText(0,tr("item2"));
}

xTreeWidget::xTreeWidget(QWidget *parent) {
    redraw();
}
void xTreeWidget::redraw() {
    //Doesn't Work
    QTreeWidgetItem *item1 = new QTreeWidgetItem(this);
    item1->setText(0,tr("item1"));
    //This don't either.
    QTreeWidgetItem *item2 = new QTreeWidgetItem;
    addTopLevelItem(item2);
    item2->setText(0,tr("item2"));
}

To copy to clipboard, switch view to plain text mode 

Any help would be greatly appreciated.

setColumnCount( 1 )?

setColumnCount( 1 )?

That's it!

Thanks for the quick reply that was killing me for some reason.
