How to create a QStyledItemDelegate made of two QDoubleSpinBox widgets

[ChrisW67]

The default behaviour will be looking to commit and close the editor when the widget you provided as the editor loses focus. I expect that widget will lose focus immediately when the focus shifts into one of its child spin boxes. You should look specifically at that event and whether you need to block it from propagating.

Cannot say I have done a lot of event filtering myself so I will be interested in the other responses.

Thanks,

It is the first time that I work explicitly with the child-parent relationship of widgets as well as with event filtering. So this is not obvious to me.

I was under the impression that the eventFilter member function of the delegate would have taken care of the out of focus event within a child of the delegate widget (line 45 of the last code snippet in my original post):

QWidget *w = QApplication::focusWidget();
while (w) { // don't worry about focus changes internally in the editor
  if (w == editor)
    return false;
  w = w->parentWidget();
}

QWidget *w = QApplication::focusWidget();
while (w) { // don't worry about focus changes internally in the editor
  if (w == editor)
    return false;
  w = w->parentWidget();
}

It seems that this is not the case. I'll run more tests.

Thanks
