Qtreewidget

i have a qdialog. And i want to open this dialog when clicked on treewidget or focus on treewidget.. not clicked on treewidgetitem...

how can i do it?

install event filter on a treewidget's viewport and process needed events.

Code:

---

...
m_treeWidget->viewport()->installEnvetFilter(this);
...
bool MyWidget::eventFilter(QObject *o, QEvent *e)
{
    if (m_treeWidget->viewport() == o) {
        if (e->type() == QEvent::MouseButtonPress) {
                const QMouseEvent *me = static_cast<QMouseEvent>(e);
                //add whatever you want
        } else if (e->type() == QEvent::FocusIn) {
                //add whatever you want
        }
    }
    return QWidget::eventFilter(o, e);
}
