Read multiple QlistWidget items to strings

[Cyrebo]

Hi, i'm working on a program where i ask a user to input certain line edits that are added as a QlistWidget item when the user clicks add. I want to able to get the QlistWidget items(line edits) and save them as a string. I see no direct way of doing this in the qlistwidget library. So far I'm passing the items to a string but not able to get them each individually.

Here's the snippet of my program where I try to do this:

//Get user inputs
    int names = ui->listWidget->count();
    for(int i = 0; i <= names; i++){
    QString list = ui->listWidget->item(i)->text();
    }

//Get user inputs
    int names = ui->listWidget->count();
    for(int i = 0; i <= names; i++){
    QString list = ui->listWidget->item(i)->text();
    }

To copy to clipboard, switch view to plain text mode 

Does anyone have an illustration or example doing something similar or the same thing?

Thanks in advance.

What do you want - all of the items concatenated into a single string, or each item as a separate string in a list of strings?

To do the first:

//Get user inputs
QString allNamesInOneString;
int names = ui->listWidget->count();
for(int i = 0; i < names; i++)
{
    allNamesInOneString += ui->listWidget->item(i)->text();
}

//Get user inputs
QString allNamesInOneString;
int names = ui->listWidget->count();
for(int i = 0; i < names; i++)
{
    allNamesInOneString += ui->listWidget->item(i)->text();
}

To do the second:

//Get user inputs
QStringList allNamesAsAList;
int names = ui->listWidget->count();
for(int i = 0; i < names; i++)
{
    allNamesAsAList << ui->listWidget->item(i)->text();
}

//Get user inputs
QStringList allNamesAsAList;
int names = ui->listWidget->count();
for(int i = 0; i < names; i++)
{
    allNamesAsAList << ui->listWidget->item(i)->text();
}

Note that your original code attempts to retrieve one too many items from the list widget. List widget item indexes go from 0 to count() - 1, not count().

Thanks for the reply, however I need the text to be read in dynamically at run time. I want to save all the text the user enters to a database dynamically and not as a list but as a seperate string for each item. I have something like this which takes the input from a grid layout and saves it each time a user clicks add but is not really ideal if you want to delete an item...

static int LayoutCount;
 
    QLineEdit *lineEdit = new QLineEdit;
 
    ui->gridLayout->addWidget( lineEdit,LayoutCount,0 );
 
    int iCount = ui->gridLayout->count(); //Total no of LineEdit added on gridLayout dynamically
    QString str;
    for(int i = 0; i < iCount; i++)
    {
    QLayoutItem* pLine = ui->gridLayout->itemAt(i);
    QLineEdit* pLineEdit = dynamic_cast<QLineEdit*>(pLine->widget()); //<<<<<<<<<<<<<<<<<<<
 
        if(pLineEdit != 0) //<<<<<<<<<<<<<<<<<<<
        {
            str = pLineEdit->text();
            ui->listWidget->addItem(str);
        }
    qDebug() << str;
    }

static int LayoutCount;

    QLineEdit *lineEdit = new QLineEdit;

    ui->gridLayout->addWidget( lineEdit,LayoutCount,0 );

    int iCount = ui->gridLayout->count(); //Total no of LineEdit added on gridLayout dynamically
    QString str;
    for(int i = 0; i < iCount; i++)
    {
    QLayoutItem* pLine = ui->gridLayout->itemAt(i);
    QLineEdit* pLineEdit = dynamic_cast<QLineEdit*>(pLine->widget()); //<<<<<<<<<<<<<<<<<<<

        if(pLineEdit != 0) //<<<<<<<<<<<<<<<<<<<
        {
            str = pLineEdit->text();
            ui->listWidget->addItem(str);
        }
    qDebug() << str;
    }

This works for only saving the item, could you please show me how to improve this to also allow for the deletion of an item?
