Why do I get a " conversion from ‘QListWidget*’ to non-scalar type ‘QList<QListWidget*>’ requested" error

[cerr]

Hi,

I've got dialogs with a QListWidget that is loaded with QListWidgetItems that are checkable. For now, I do not care about which one is checked and which one isn't, but instead, I just want to ierate through all the items in the widget but turns out, I can't even find the widget, what I have looks like:

        QSettings *sttngs = new QSettings(QSettings::NativeFormat,QSettings::UserScope,"GNU","SCAPER",nullptr);
	sttngs->beginGroup(nme_get());
	sttngs->setValue("size", this->size());
	sttngs->endGroup();
	sttngs->beginGroup("tooloptions");
	QList <QListWidget *> wdgt = this->findChild<QListWidget *>();

and what I get for the bottom line is a compiler error:
error: conversion from ‘QListWidget*’ to non-scalar type ‘QList<QListWidget*>’ requested
pointing at:

QList <QListWidget *> wdgt = this->findChild<QListWidget *>();
                                                           ^

and I'm not exactly sure why, if someone could enlighten me, that would be great & appreciated

@cerr Well, because

QList<QListWidget*>

is not the same as

QListWidget*

and can't be implicitly converted.
What you want is:

QList <QListWidget *> wdgt;
wdgt.append(this->findChild<QListWidget *>());

@jsulm Excellent! Thank you my friend!
