Question

I’ve created some dialog and on this dialog I have a vertical layout consisting of few checkboxes. I’d like to access those checkboxes during runtime via layout containing them. Is this possible?

Answer 1

If you have a dialog called myDialog you can access its layout via

myDialog->layout()

the layout itself inherits from QObject and like that has access to the QObject::children() method.

For example you could do something like this:

QCheckBox* currentCheckBox;
foreach( QObject* child, myDialog->layout()->children() )
{
    currentCheckBox = qobject_cast< QCheckBox* >( child );
    if( !currentCheckBox ) continue;

    // do anything with the checkbox here
}
