QList find subclass class objects using qobject_cast
-
Hi All,
It's getting late and my brain has stopped working, so apologies if this is a stupid question.
If I have a qlist<QObject*> containing a load of object that have been inherited from QObject (and have the Q_OBJECT macro), what would be the best way to construct a find operation that would return a list of a particular base class type.
E.g A function prototype could look like :
@QList<T> find(T type)@Can I intergrate it into a iterator?

Hi,
Do you mean
@
template<T>
QList<T > find(QList<QObject> inputList)
{
QList<T *> objectList;
foreach (QObject *inputObject, inputList) {
T *object = qobject_cast<T *>(inputObject);
if (object) {
objectList << object;
}
}
return objectList
}
@?
