C++ (Cpp) itemAtIndex Examples

Example #1

File: NValue.cpp Project: DarkDare/voltdb

void NValue::castAndSortAndDedupArrayForInList(const ValueType outputType, std::vector<NValue> &outList) const
{
    int size = arrayLength();

    // make a set to eliminate unique values in O(nlogn) time
    std::set<StlFriendlyNValue> uniques;

    // iterate over the array of values and build a sorted set of unique
    // values that don't overflow or violate unique constaints
    // (n.b. sorted set means dups are removed)
    for (int i = 0; i < size; i++) {
        NValue value = itemAtIndex(i);
        // cast the value to the right type and catch overflow/cast problems
        try {
            StlFriendlyNValue stlValue;
            stlValue = value.castAs(outputType);
            std::pair<std::set<StlFriendlyNValue>::iterator, bool> ret;
            ret = uniques.insert(stlValue);
        }
        // cast exceptions mean the in-list test is redundant
        // don't include these values in the materialized table
        // TODO: make this less hacky
        catch (SQLException &sqlException) {}
    }

    // insert all items in the set in order
    std::set<StlFriendlyNValue>::const_iterator iter;
    for (iter = uniques.begin(); iter != uniques.end(); iter++) {
        outList.push_back(*iter);
    }
}

Example #3

File: GridView.cpp Project: 91yuan/ilixi

void

Example #5

File: queuemanager.cpp Project: tmarques/waheela

void
QueueList::moveSelectedUp() // SLOT
{
    QPtrList<QListViewItem> selected = selectedItems();

    // Whilst it would be substantially faster to do this: ((*it)->itemAbove())->move( *it ),
    // this would only work for sequentially ordered items
    for( QListViewItem *item = selected.first(); item; item = selected.next() )
    {
        if( item == itemAtIndex(0) )
            continue;

        moveItem( item, 0, after );
    }

    ensureItemVisible( selected.first() );
}

Example #6

File: basketmodel.cpp Project: elemc/basketpwd

Example #7

File: usermenutree.cpp Project: fagu/kileip
