Edit Feature works perfect if I do not change index...

[giblit]

I am not sure what I did wrong..but it only works 100% if say the first item I edited was index 1. then The second item I want to edit would also have to be index 1 if the second item I try to edit is index 0... it Will not work it will basically not take in the info that is supposed to be there.
here is the code:

void DateListDialog::updateTreeWidget(){
    for (int i = 0; i < dates.size(); ++i) {
 
        itemParent = new QTreeWidgetItem(treeWidget);
        for(int j = 0; j<24; j++){
            timeChild[j] = new QTreeWidgetItem(itemParent);
            //timeChild[j]->setFlags(Qt::NoItemFlags);
        }
 
        itemParent->setText(1, foods[i]);
        for(int k = 0; k<7; k++){
            itemParent->setText(k+2, totalValues[k+(7*i)]);
            //cout << totalValues[k+(7*i)].toStdString() << endl;
        }
 
        itemParent->setText(0, dates[i]);
 
            for(int j = 0; j<24; j++){
                timeChild[j]->setText(1, times[j+(24*i)]);
            }
 
        for(int i = 0; i<24; i++){
            if(i == 0){
                time = "12 AM";
            } else if(i > 0 && i < 12){
            time = QString("%1 AM").arg(i);
            } else if(i == 12){
                time = "12 PM";
            } else if(i > 12){
                time = QString("%1 PM").arg(i-12);
            }
        timeChild[i]->setText(0, time);

I think it would work perfect if...I could edit the old one with out removing them. how would I go about updating my QTreeWidget via a QDialog
I am going to keep trying to figure it out while I wait but any advice/suggestions would be appreciated =]

EDIT:::EDIT::
argh...the reason it wasnt working correctly was because instead of

if(!allTimes[i].....);
 //was suppsed to be
if(!allTimes[i+(24*posInt)]......)

if(!allTimes[i].....);
 //was suppsed to be
if(!allTimes[i+(24*posInt)]......)

I would still like to know if there is a more efficient way that would be to just edit the old item and update instead of editing old item, removing it, then reinserting at the end.
