QT ButtonGroup and checkable PushButtons: how to connect toggled signal with int and bool?

Question

I have connected non-checkable push buttons from a ButtonGroup like this

connect(buttonGroupPtr, SIGNAL(buttonReleased(int)), this, SLOT(someFunction(int)));

now I want the Buttons to be checkabel and use the toggled() signal, which emits a bool . How do i combine the int that is emitted by the ButtonGroup and the bool that is emitted by the toggled() signal?

Answer 1

QButtonGroup has buttonToggled(int id, bool checked) signal you can find here . So you can

connect(buttonGroupPtr, SIGNAL(buttonToggled(int, bool)), this, SLOT(someFunction(int, bool)));

Answer 2

触发信号必须在另一个connect语句中连接。

connect(buttonGroupPtr, SIGNAL(toggled(bool)), this, SLOT(mySlotToggled(bool)));
