[Qt-interest] QFileSystemModel and QTreeView interesting problemH

[Denis Akhmetzyanov]

Hi,
Screenshot looks like only one column is visible and it is file modification
(or creation) time. You could resize first column (filename) manually:

    QFileSystemModel *treeModel = new QFileSystemModel(this);
    QTreeView *treeView = new QTreeView(this);
    treeView->setModel(treeModel);
    QModelIndex index = treeModel->setRootPath(QDir::homePath());
    treeView->scrollTo(index);
    treeModel->setFilter(QDir::AllDirs | QDir::AllEntries | QDir::System |
QDir::Hidden | QDir::NoDotAndDotDot);
    treeModel->setReadOnly(true);

    setCentralWidget(treeView);
    showMaximized();
    enum { FILENAME_COLUMN = 0 };
    treeView->setColumnWidth(FILENAME_COLUMN, 300);

I've attached screenshots as it looks on my machine for Ubuntu 9.10, Qt
4.6.2 and WinXP, Qt 4.6.0.
