How to get QPixmap from QItemSelection?
-
Hello.
How can I get QPixmap from QItemSelection?
I am trying to make an image viewer. Currently, I have successfully loaded images to QstandarditemModel as below.
Now, I would like to show an enlarged image which is selected by mouse clicked. To do so, I think, first, I should get QPixmap from QItemSelection in order to show into QLabel Box.Please help.
Thank you.
@
this->model = new QStandardItemModel();
ui->listView->setModel(this->model);
ui->listView->setGridSize(QSize(320, 240));
ui->listView->setIconSize(QSize(280, 200));
ui->listView->setViewMode(QListView::IconMode);
QObject::connect(ui->listView->selectionModel(), SIGNAL(selectionChanged(QItemSelection, QItemSelection)), this, SLOT(imageSelectionChanged(QItemSelection)));//---------Load Button Event ------------
QFileDialog::Options options;
options |= QFileDialog::DontUseNativeDialog;QString selectedFilter;
QStringList fileNames = QFileDialog::getOpenFileNames(this, tr("QFileDialog::getOpenFileNames()"), "./../data", tr("All Files ();;Image Files (.bmp)"), &selectedFilter, options);
for (int i = 0; i < fileNames.count(); i++) {
QStandardItem *item = new QStandardItem(QIcon(fileNames[i]), fileNames[i]);
this->model->appendRow(item);
}

Hi and welcome to devnet,
You should rather load it from the same file used to create the icon. Your QIcon will have a reduced version of the image while you rather want to have the original.
