Opens a modal file dialog and returns the name of the file to be
saved.
If \a startWith is the name of a directory, the dialog starts off in
that directory. If \a startWith is the name of an existing file,
the dialogs starts in that directory, and with \a startWith
selected.
Only files matching \a filter are selectable. If \a filter is QString::null,
all files are selectable. In the filter string multiple filters can be specified
seperated by either two semicolons next to each other or seperated by newlines. To add
two filters, one to show all C++ files and one to show all header files, the filter
string could look like "C++ Files (*.cpp *.cc *.C *.cxx *.c++);;Header Files (*.h *.hxx *.h++)"
If \a widget and/or \a name is provided, the dialog will be centered
over \a widget and \link QObject::name() named \endlink \a name.
Returns a \link QString::isNull() null string\endlink if the user
cancelled the dialog.
This static function is less capable than the full QFileDialog object,
but is convenient and easy to use.
Example:
\code
// start at the current working directory and with *.cpp as filter
QString f = QFileDialog::getSaveFileName( QString::null, "*.cpp", this );
if ( !f.isEmpty() ) {
// the user gave a file name
} else {
// the user cancelled the dialog
}
\endcode
getOpenFileName() is another convenience function, equal to this one
except that it does not allow the user to specify the name of a
nonexistent file name.
NOTE: In the windows version of Qt this static method uses the native
windows file dialog, and not the QFileDialog.

By default, QFileIconProvider is not used, but any application or

icon, and make all QFileDialog objects use it by calling the static
function QFileDialog::setIconProvider().
It's advisable to make all the icons QFileIconProvider returns be of
the same size, or at least the same width. This makes the list view

The default is all files. In the filter string multiple filters can be specified

two filters, one to show all C++ files and one to show all header files, the filter
string could look like "C++ Files (*.cpp *.cc *.C *.cxx *.c++);;Header Files (*.h *.hxx *.h++)"

dir is not supplied, QFileDialog picks something presumably useful
(such as the directory where the user selected something last, or

\a parent is a widget over which the dialog should be positioned and
\a name is the object name of the temporary QFileDialog object.

\class QFilePreview qfiledialog.h
\brief Abstract preview widget for the QFileDialog
This class is an abstract base class which is used for implementing
widgets which can display a preview of a file in the QFileDialog.
If you want to do that you have to derive your preview widget
from any QWidget and from this class. Then you have to reimplement
the previewUrl() method of this class which is called by the filedialog
if the preview of an URL should be shown.
See also QFileDialog::setPreviewMode(), QFileDialog::setContentsPreview(),
QFileDialog::setInfoPreview(), QFileDialog::setInfoPreviewEnabled(),
QFileDialog::setContentsPreviewEnabled().
For an example documentation of a prview widget look at the example
qt/examples/qdir/qdir.cpp.
