Problems with QTreeview + QFileSystemModel

[HankQ]

Hello,

I use QFileSystemModel and Qtreeview for a directoryview. If a folder has a subfolder and the subfolder was expanded anytime before, I can`t rename this folder.
Any hints how I could fix that?

@#include <QtGui>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QFileSystemModel filemodel;
filemodel.setRootPath("");
QTreeView treeview;
treeview.setModel(&filemodel);
filemodel.setReadOnly(false);

treeview.setIndentation(20);
treeview.setSortingEnabled(true);
filemodel.setReadOnly(false);

treeview.setWindowTitle(QObject::tr("Dir View"));

#if defined(Q_OS_SYMBIAN) || defined(Q_WS_MAEMO_5)
tree.showMaximized();
#else
treeview.resize(640, 480);
treeview.show();
#endif

return app.exec();

}
