Description

QFileDialogs with AnyFile are broken in 4.2.3.  This is actually a QListView bug that shows up in QFileDialog.

What happens is that you get all the files in the ListView lined up horizontally without wrapping. In other words you get a horizontal scrollbar with a long range and a lot of unused screen real estate.

Example:

#include <QApplication>
#include <QFileDialog>
#include <QString>
#include <QLibraryInfo>

int main(int argc, char** argv)
{
    QApplication app(argc, argv);
    QFileDialog dialog(0, QString(),
                       QLibraryInfo::location(QLibraryInfo::ExamplesPath));
    dialog.setFileMode(QFileDialog::AnyFile);
    dialog.exec();
    return 0;
}

This patch fixes the problem:
