Hi,

I have a requirement to display images as a list. I have done this using QListWidget. Here when I double click the icon it has to save the icon somewhere as png. Can you please help me how to do this.

What I have tried:

The below is my code

ui->listWidget_img->setViewMode(QListWidget::IconMode);
ui->listWidget_img->setResizeMode(QListWidget::Adjust);
ui->listWidget_img->setIconSize(QSize(200,200));
ui->listWidget_img->setEditTriggers(QAbstractItemView::NoEditTriggers);
ui->listWidget_img->setMovement(QListView::Static);

QListWidgetItem *item1 = new QListWidgetItem(QIcon("/root/Icons/IssuePass.png"),QString("IssuePass.png"));
QListWidgetItem *item2 = new QListWidgetItem(QIcon("/root/Icons/Network.png"),QString("Network.png"));
QListWidgetItem *item3 = new QListWidgetItem(QIcon("/root/Icons/Orginfo.png"),QString("Orginfo.png"));
QListWidgetItem *item4 = new QListWidgetItem(QIcon("/root/Icons/Password.png"),QString("Password.png"));
ui->listWidget_img->addItem(item1);
ui->listWidget_img->addItem(item2);
ui->listWidget_img->addItem(item3);
ui->listWidget_img->addItem(item4);

icon double clicked

void Widget::on_listWidget_img_itemDoubleClicked(QListWidgetItem *item)
{
Here I have to save the item into png file in some path("/root/myicon.png")
}

How it is possible.

Sorry, no idea. I suggest reading the documentation, or searching with Google.
