List of child widgets includes layout

[JovianGhost]

I've got an app that changes around the GUI layout based on user input.

So for part of it, I have a container, which is just a QFrame, which will hold different types of other widgets, but only one at a time. So I need to get the widget from this container, as follows:

QWidget* w = (QWidget*)(ui->container->children()->at(0));

QWidget* w = (QWidget*)(ui->container->children()->at(0));

To copy to clipboard, switch view to plain text mode 

The problem is, w will now point to the LAYOUT object of the container, rather than the widget in the container. In order to get a handle on the widget itself, I have to use

at(1)

at(1)

To copy to clipboard, switch view to plain text mode 

instead.

This doesn't really sound right to me; I think of the layout is a mechanism for organizing the widgets in another widget, and not as a widget itself. Also, having 0 refer to the layout and 1 refer to the widget makes it seem more like the layout and widget are siblings, which of course isn't right.

Is there a less clunky way to do this, or is this just the nature of the beast?

Did you come across QStackedWidget

children() returns a list of objects, not a list of widgets. The layout is reparented to the widget it is in and widgets inside the layout are reparented to the widget containing the layout so yes, this effectively makes the layout object and child widgets objects siblings.

Yes, but not what I'm looking for.

Ok, that makes sense, thanks.
Is there a way to get *just* a list of child widgets, or would I have to check each child and see if it's a derivative of QWidget?

Maybe QObject::findChildren() is what you are looking for:

ui->container->findChildren<QWidget *>()

ui->container->findChildren<QWidget *>()

To copy to clipboard, switch view to plain text mode

Yep, that works, thanks!
