c++ - Qt，没有这样的插槽

Question

为什么会这样

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

当我尝试这样做时:

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。

Answer 1

请像这样插入函数原型(prototype):

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

您使用的这种格式不常用于插槽。信号和槽的参数应该相同。
