\class QPageSetupDialog
\brief The QPageSetupDialog class provides a configuration dialog
for the page-related options on a printer.
\ingroup standard-dialogs
\ingroup printing
\inmodule QtPrintSupport
On Windows and \macos the page setup dialog is implemented using
the native page setup dialogs.
Note that on Windows and \macos custom paper sizes won't be
reflected in the native page setup dialogs. Additionally, custom
page margins set on a QPrinter won't show in the native \macos
page setup dialog.
