This class represents the page setup common dialog. The page setup dialog is standard from Windows 95 on, replacing the print setup dialog (which is retained in Windows and wxWidgets for backward compatibility). On Windows 95 and NT 4.0 and above, the page setup dialog is native to the windowing system, otherwise it is emulated.
The page setup dialog contains controls for paper size (A4, A5 etc.), orientation (landscape or portrait), and controls for setting left, top, right and bottom margin sizes in millimetres.
When the dialog has been closed, you need to query the wxPageSetupDialogData object associated with the dialog.
Note that the OK and Cancel buttons do not destroy the dialog; this must be done by the application.
Constructor. Pass a parent window, and optionally a pointer to a block of page setup data, which will be copied to the print dialog's internal data.
Returns the page setup data associated with the dialog.
Shows the dialog, returning wxID_OK if the user pressed OK, and wxID_CANCEL otherwise.
