50 \brief The QPageSetupDialog class provides a configuration dialog
51 for the page-related options on a printer.
52
53 \ingroup standard-dialogs
54 \ingroup printing
55 \inmodule QtPrintSupport
56
57 On Windows and \macos the page setup dialog is implemented using
58 the native page setup dialogs.
59
60 Note that on Windows and \macos custom paper sizes won't be
61 reflected in the native page setup dialogs. Additionally, custom
62 page margins set on a QPrinter won't show in the native \macos
63 page setup dialog.
