Iterate over a QList with QFile's

NeedDeen

Hi

Is there an easy way to iterate over a QFile QList like this. I need to check, if a new item already exists:

Pseudocode:
@QList<QFile *> list;

void addItem(QFile *file)
{
for(Begin List; Until End; One item)
{
if(compare file with the QFile item from the current iteration) return;
}
// Add item
}@

Hi!

Try:

@if(!list.isEmpty())
foreach(QFile *i, list)
{
//Your code here
}@

mlong

@foreach(QFile *i, list)
{
//Your code here
}@ would be sufficient. If the list were empty, the foreach wouldn't loop at all.

Edited to add:

I agree with the posts following this one. There is a much better way to solve the original problem. I was just commenting on the post directly above.

Much easier:
@ if (!list.contains(file))
list.append(file);@

Be aware that the foreach is much more code consuming then the C-style for loop, but if it isn't used a lot, the foreach is the way to go ;-)
The correct use of the iterator is more like this:
@QList<QFile *>::iterator i;@
