c++ - Qt，没有这样的插槽

Question

为什么我会得到这个

Object::connect: No such slot Ide::on_action_Exit_triggered(index)
Object::connect:  (sender name:   'actionClose_Project')
Object::connect:  (receiver name: 'Ide')

当我尝试这个时：

connect(this->ui->actionClose_Project, SIGNAL(triggered()), this, SLOT(on_action_Exit_triggered(index)));

void Ide::on_action_Exit_triggered(int index)
{
  qDebug()<<"test\n";
}

谢谢你。

Answer 1

Please insert prototype of function like this :

connect(this->ui->actionClose_Project, SIGNAL(triggered()), this, SLOT(on_action_Exit_triggered(int)));

This format you use isn't common to use slot. the signal and slot should be same in parameters.
