Question

I was wondering if anyone knows of a library method or function within Qt that will tell you when you’ve hit the last object in a foreach.

Below I’m rolling on a list of strings and I’ve made up a fictional method below called “isLast()”:

foreach( QString a_string, string_list )
{
    if ( a_string.isLast() )   // does something like this exist?
    {
    ...
    }
}

Does anyone know if anything like “isLast()” exists?

Thanks,
Wes

I’ve not seen an isLast()-style function around QT. Your best bet is probably to mix in a little old-school counter logic:

int str_count = 0;
int str_list_last_elem = string_list.size()-1;

foreach(QString a_string, string_list) {
    str_count++;
    if (str_count == str_list_last_elem) {
        ...
    }
}
