I have the follwing code where <code>moreButton</code> is a <code>QPushButton</code>. When I toggle the button, nothing happens. Shouldn't it show or hide <code>secondaryGroupBox</code> and <code>tertiaryGroupBox</code>? <pre class="prettyprint"><code>QObject::connect(moreButton, SIGNAL(toggled(bool)), secondaryGroupBox, SLOT(setVisible(bool))); QObject::connect(moreButton, SIGNAL(toggled(bool)), tertiaryGroupBox, SLOT(setVisible(bool))); </code></pre>

Most likely, your pushbutton is not <code>checkable()</code>. Try <pre class="prettyprint"><code>moreButton->setCheckable(true) </code></pre> A non-checkable button never emits the <code>toggled(bool)</code> signal.

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