[SOLVED] howto write a qstringlist from a listwigdet

mr_maddog

Hi,

I want to write a qstringlist from data wich is in a listwidget. Idea is that the user selects data in the listwigdet he doesnt want. The resulting qstringlist should than written to a file.

This is for deleting data out of the widget
@QListWidgetItem* item = ui->listWidget->takeItem(ui->listWidget->currentRow());
delete item;@

How do i now write the content of listwidget in a qstringlist?

Thanks

Iterate all the items, take their text(), append to a QStringList, then write to a file.

Hi,

you have a code snippet for me. i am not that good in programming.

@QListWidget * listWidget = ui->listWidget;
QListWidgetItem * item;
QStringList stringList;

// Read all items text and put in a string list
for(int i = 0; i < listWidget->count(); i++)
{
item = listWidget->takeItem(i);
stringList << item->text();
}

// write string list to a file
QFile file("StringList.txt");
if(file.open(file.WriteOnly | file.Text))
{
const QByteArray data= stringList.join("\n").toAscii();
file.write(data);
file.close();
}@

Thanks alot,

here for all who will have the same problem. This is my code

@
//Multiple selection inside the listwidget and delete selected items
ui->listWidget->setSelectionMode(QAbstractItemView::ExtendedSelection);
foreach (QListWidgetItem* item, ui->listWidget->selectedItems())
delete item;

//qstringlist of the left items inside the listwidget
QStringList pickedItem;
QList<QListWidgetItem*> tmpList = ui->listWidget->findItems(QString("*"), Qt::MatchWrap | Qt::MatchWildcard);
for (int i = 0; i < tmpList.size(); ++i)
pickedItem.append(tmpList.at(i)->text());

//write to a file
QFile newloads("/fs1/PerlQt/QtCreator/test/newloads.inp");
newloads.open(QFile::WriteOnly|QFile::Truncate|QFile::Text);
QTextStream out(&newloads);
out << pickedItem.join("\n");
newloads.close();@
