QDateTimeEdit : Dumb Mistake or bug?

[ChrisW67]

I refined it and lodged a bug
https://bugreports.qt-project.org/browse/QTBUG-34759

It appears that the focusInEvent() is resetting the currentSection() so I am working around this by subclassing QDateTimeEdit, which is OK for my purposes:

class Edit: public QDateTimeEdit {
public:
    Edit(QWidget *p): QDateTimeEdit(p) { }
protected:
    void focusInEvent(QFocusEvent *event) {
        Section section = currentSection();
        QDateTimeEdit::focusInEvent(event);
        setSelectedSection(section);
    }
};

class Edit: public QDateTimeEdit {
public:
    Edit(QWidget *p): QDateTimeEdit(p) { }
protected:
    void focusInEvent(QFocusEvent *event) {
        Section section = currentSection();
        QDateTimeEdit::focusInEvent(event);
        setSelectedSection(section);
    }
};
