How to remove duplicate enteries from QStringList.

[merry]

Hi all

Working on Qt 4.4.2 on my intel mac machine.

Pls tell How to remove duplicate enteries from QStringList.

if you do not care about the order of the list:

QStringList sl = ...;
sl = sl.toSet().toList();

QStringList sl = ...;
sl = sl.toSet().toList();

To copy to clipboard, switch view to plain text mode 

Maybe there are more efficient ways to do that.

Or you could do

for (int i=0; i<sl.count(); ++i)
{
   forever { // remove all occurrences at greater indexes
      int p=sl.lastIndexOf(sl.at[i]);
      if (p==i) break;
      sl.removeAt(p);
   }
}

for (int i=0; i<sl.count(); ++i)
{
   forever { // remove all occurrences at greater indexes
      int p=sl.lastIndexOf(sl.at[i]);
      if (p==i) break;
      sl.removeAt(p);
   }
}

To copy to clipboard, switch view to plain text mode 

Untested, of course. Have, fun!
