Example 13.1 shows what may be the simplest Qt model-view example.

Example 13.1. src/modelview/filesystem/main.cpp

#include <QtGui>
int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
    QFileSystemModel model;                
    model.setRootPath("/");           
    QTreeView tree;
    tree.setModel(&model);                 
    tree.setSortingEnabled(true);    
    tree.header()->setResizeMode(QHeaderView::ResizeToContents);
    tree.resize(640, 480);
    tree.show();   
    return app.exec();
}

Enable HeaderView sort buttons.

By setting the resizeMode in the headerView, the columns of the table or tree will be resized whenever the window is.
These classes are the basic building blocks for writing a file browser widget.
