How to get toggled() signal working with a QPushButton?

Question

I have the follwing code where moreButton is a QPushButton. When I toggle the button, nothing happens.

Shouldn't it show or hide secondaryGroupBox and tertiaryGroupBox?

QObject::connect(moreButton, SIGNAL(toggled(bool)), secondaryGroupBox, SLOT(setVisible(bool)));
QObject::connect(moreButton, SIGNAL(toggled(bool)), tertiaryGroupBox, SLOT(setVisible(bool)));

Answer 1

Most likely, your pushbutton is not checkable(). Try

moreButton->setCheckable(true)

A non-checkable button never emits the toggled(bool) signal.
