How to get the widget from QScrollArea with the index of widget?

How to get the widget from QScrollArea with the index of the widget in scroll area? I have the index of widget and want to delete it from the scrollArea. But I can't find any solution.

@Mikiqueen
What index? Do you mean you have added widgets to a layout and want to remove one of them?

Or, every QObject can use findChild() to try to find a particular child. is that relevant?

@Mikiqueen QScrollArea only holds one widget so there is no index. That widget can have children, but their order is unspecified. A widget can have layout set and you can get a layout element with specified index. From layout element you can get a widget it hosts if it has any.

Whether that's what you want or not I couldn't tell you. You didn't say where that index you have comes from.

@Chris-Kawa I get the index from the order I add widget to scroll area (I track and store the index of widget added order). Thank you so much I use .itemAt(index) to locate the widget.

Since you can't add multiple widgets to a QScrollArea

The QScrollArea class provides a scrolling view onto another widget

A scroll area is used to display the contents of a child widget within a frame. [...] The child widget must be specified with setWidget()

void QScrollArea::setWidget(QWidget *widget)

Sets the scroll area's widget.

In view of the above (i.e. one widget) don't you think you had better show (a minimal example of) how you add all these widgets:

I get the index from the order I add widget to scroll area (I track and store the index of widget added order).

I use .itemAt(index) to locate the widget

QScrollArea does not have any itemAt().

@JonB Oh I understand now. Thanks for your reply. I'm so new to this tools so there are so many things I don't fully understand
