QPushButton if passed by reference to initialize, app crashing on connect statement

That doesn't look like something that would compile.

"pb" is of type QPushButton* but the method return value is of type QToolButton*, so either of the two needs to be changed.

Adding the button to the layout in there should be OK

Oh sorry for the typo. I meant QToolButton there.
Thank you.

To your code from the first post: You don't pass a QPushButton by reference. You pass "a pointer to QPushButton by value". That's why btn1/2/3/4 doesn't change after calling addButtons - just a copy of that pointer changes.
The following piece of code might work.

void MyWidget::addButtons(QPushButton *&pb, const QString &str)
{
pb = new QPushButton(this);
pb->setCheckable(true);
pb->setStyleSheet(str);
vLyt->addWidget(pb);
}

void MyWidget::addButtons(QPushButton *&pb, const QString &str)
{
pb = new QPushButton(this);
pb->setCheckable(true);
pb->setStyleSheet(str);
vLyt->addWidget(pb);
}
