Access the children from the QScrollArea - qt

Question

I have added a QScrollArea widget in QDialog form.
In the scrollarea, I have added 16 chcekboxes.
I want to loop inside the scrollarea and check for which of the checkboxes are checked.
Can anyone please help me with this. Thanks in advance!
The code for ScrollArea and Checkbox is like this:
<widget class="QScrollArea" name="scrollArea">
<property name="geometry">
<rect>
<x>20</x>
<y>320</y>
<width>271</width>

This can be accomplished with the QObject::findChildren method.
An example code in your .cpp file that belongs to the .ui file would look like this:
QList<QCheckBox *> allCheckBoxes = this->findChildren<QCheckBox *>();
for (QCheckBox *checkBox: allCheckBoxes) {
if (checkBox->isChecked()) {
qDebug() << "CheckBox with object name " << checkBox->objectName() << " is checked";
}
}
