I was reading MVC tutorial and wanted to try out the code, but for some reason (which I'm not able to figure out) it is not working.
This code is suppose to show contents of current directory in QListWidget.
#include <QApplication>
#include <QFileSystemModel>
#include <QModelIndex>
#include <QListWidget>
#include <QListView>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QFileSystemModel *model = new QFileSystemModel;
QString dir = QDir::currentPath();
model->setRootPath(dir);
QModelIndex parentIndex = model->index(dir);
int numRows = model->rowCount(parentIndex);
QListWidget *list = new QListWidget;
QListWidgetItem *newItem = new QListWidgetItem;
for(int row = 0; row < numRows; ++row) {
QModelIndex index = model->index(row, 0, parentIndex);
QString text = model->data(index, Qt::DisplayRole).toString();
newItem->setText(text);
list->insertItem(row, newItem);
}
list->show();
return a.exec();
}
