getting QString out of QListWidget

[tommy]

Hello,

I have a QListWidget list that I first fill with QStrings, then sort the list, and then I want to get the QStrings back out of the list. I don't know how to do that. Can you help? Below is my code with comments.

//"number" and "features" are int values
//"dataTable" is a table of integers
 
//declare QListWidget list
QListWidget sList = new QListWidget(this);
 
//fill QListWidget list with entries
for(int k=0; k<number+1; k++)
{
    QString entry;
       for(int i=0; i<features+1; i++)
       {
       entry.append(dataTable[i][k]);
       entry.append(",");
       }
  sList->insertItem(k, entry);
}
 
//sort list entries in ascending order  
sList->sortItems(Qt::AscendingOrder);
 
//get the list entries back in the QString format
//I DON'T KNOW HOW??
//QString entry2 = sList.itemAt(1); for example won't work

//"number" and "features" are int values
//"dataTable" is a table of integers

//declare QListWidget list
QListWidget sList = new QListWidget(this);

//fill QListWidget list with entries
for(int k=0; k<number+1; k++)
{
    QString entry;
       for(int i=0; i<features+1; i++)
       {
       entry.append(dataTable[i][k]);
       entry.append(",");
       }
  sList->insertItem(k, entry);
}

//sort list entries in ascending order  
sList->sortItems(Qt::AscendingOrder);

//get the list entries back in the QString format
//I DON'T KNOW HOW??
//QString entry2 = sList.itemAt(1); for example won't work

To copy to clipboard, switch view to plain text mode 

Thanks!

Set this property to true first.

void setSortingEnabled ( bool enable )

void setSortingEnabled ( bool enable )

To copy to clipboard, switch view to plain text mode

Try:

QString str = sList.item(1)->text();

QString str = sList.item(1)->text();

To copy to clipboard, switch view to plain text mode

Thanks!
However when I try to compile

QString entry2 = sList.item(1)->text();

QString entry2 = sList.item(1)->text();

To copy to clipboard, switch view to plain text mode 

I get:
error: 'item' has not been declared

But item is a function of QListWidgetItem, so why/where would I declare 'item'?
Is this happening because I don't build my QListWidget right?
Thanks!

Is your existing code is working after setting the property ?

[spirit]

you should use operator ->

QString entry2 = sList->item(1)->text();

QString entry2 = sList->item(1)->text();

To copy to clipboard, switch view to plain text mode 

since you created sList in the heap.

Yes, everything else is working properly. I just cannot get the QString back from the QList Widget.

Hi Spirit,

Of course, you are correct. Everything is fixed now. Thanks!
