How can I sort this list? This list contains strings. I want to sort the fieldList alphabetically?

推荐答案

我将按照以下方式进行排序:

I would do sorting in the following way:

 // Compare two variants.
 bool variantLessThan(const QVariant &v1, const QVariant &v2)
 {
     return v1.toString() < v2.toString();
 }

 int doComparison()
 {
     [..]
     QList<QVariant> fieldsList;

     // Add items to fieldsList.

     qSort(fieldsList.begin(), fieldsList.end(), variantLessThan);
 }
