Question

QT 中动态添加checkbox，怎么在触发的信号中获取点击的checkbox的text

Answer 1

比如

void AddCheckBox()
{
QStringList list;
list<<"one"<<"two"<<"three";

foreach(QString number,list)
{
QCheckBox *button = new QCheckBox(number,this);
widget添加button
connect(button,SIGNAL(clicked()),this,SLOT(getButtonText()));

}

}

void getButtonText()
{
QCheckBox *button = (QCheckBox * )(sender()); //关键一步是利用sender（）
qDebug()<<"button text:"<<button->text();

}

QObject * QObject::sender () const [protected]
返回发射信号类的指针，

我也是刚做出来，本来想着自己弄出来就不写了，想一想，写出来如果能帮助到别人，何乐而不为啦

Answer 2

connect(m_check, SIGNAL(clicked()), this, SLOT(OnCheck()));

void XXX::OnCheck{
m_check->text();

}
