[SOLVED] Pass QList with undefined size

[david.luggen]

Hey there

I'm afraid that this isn't working anyway, but maybe somebody has a good idea.

I'm looking for the possibility to pass a QList Array to a function as a parameter. So far everything is fine. But now, the point is, I don't know how big the array is and so I can't do further actions with the data. Below a little example:

@
void MyFunction(QList<int> passedList[])
{
myList[0] = passedList[0];
myList[1] = passedList[1];
...
}
@

This is how it works, but therefore I need to know how big the passed list is going to be. How could this be achieved without that information?

When you pass an c-style array to a function add another parameter and pass the size too.
Also you can use another QList and pass a QList<QList<int> > param and then you don't need to pass the size anymore.

QList in a QList, already tried, didn't worked and why. Because of the space between > and >. True story! : )
Thx!

Yeap, compilers require you to write @QList<QList<int> >@ because ">>" is an operator and the compilers are too stupid to distinguish between those two meanings. That is a well known pitfall.

This was changed in the new C++11 standard by the way.
