我想将一个QObject的所有信号连接到某个插槽。
插槽看起来像这样:
void SignalIntercepter::signalFired()
{
std::cout << "Signal is fired!" << std::endl;
}
以下代码是QObject传递给的地方:
void SignalIntercepter::handleObject(QObject* object)
{
const QMetaObject *me = object->metaObject();
int methodCount = me->methodCount();
for(int i = 0; i < methodCount; i++)
{
QMetaMethod method = me->method(i);
if(method.methodType() == QMetaMethod::Signal)
{
// How do I connect this signal to the slot?
// QObject::connect(object, ..., ..., ...);
}
}
}
答案 0 :(得分:2)
看看
const char * QMetaMethod::signature() const
那么你应该可以像
一样使用它QObject::connect(object, method->signature(), this, SLOT(signalFired()));
您可能需要在"2"
来电之前添加method->signature()
,因为SIGNAL(a)
makro定义为SIGNAL(a) "2"#a
,如上所述Is it possible to see definition of Q_SIGNALS, Q_SLOT, SLOT(), SIGNAL() macros? (Qt)
