\section{\class{wxPrintDialog}}\label{wxprintdialog}

This class represents the print and print setup common dialogs.
You may obtain a \helpref{wxPrinterDC}{wxprinterdc} device context from
a successfully dismissed print dialog.

\membersection{wxPrintDialog::wxPrintDialog}\label{wxprintdialogctor}

\func{}{wxPrintDialog}{\param{wxWindow* }{parent}, \param{wxPrintDialogData* }{data = NULL}}

Constructor. Pass a parent window, and optionally a pointer to a block of print
data, which will be copied to the print dialog's print data.

\helpref{wxPrintDialogData}{wxprintdialogdata}


\membersection{wxPrintDialog::\destruct{wxPrintDialog}}\label{wxprintdialogdtor}

\func{}{\destruct{wxPrintDialog}}{\void}

Destructor. If wxPrintDialog::GetPrintDC has {\it not} been called,
the device context obtained by the dialog (if any) will be deleted.


\membersection{wxPrintDialog::GetPrintDialogData}\label{wxprintdialoggetprintdialogdata}

\func{wxPrintDialogData\&}{GetPrintDialogData}{\void}

Returns the \helpref{print dialog data}{wxprintdialogdata} associated with the print dialog.


\membersection{wxPrintDialog::GetPrintDC}\label{wxprintdialoggetprintdc}

\func{wxDC* }{GetPrintDC}{\void}

Returns the device context created by the print dialog, if any.
When this function has been called, the ownership of the device context
is transferred to the application, so it must then be deleted
explicitly.


\membersection{wxPrintDialog::ShowModal}\label{wxprintdialogshowmodal}

\func{int}{ShowModal}{\void}

Shows the dialog, returning wxID\_OK if the user pressed OK, and wxID\_CANCEL
otherwise. After this function is called, a device context may
be retrievable using \helpref{wxPrintDialog::GetPrintDC}{wxprintdialoggetprintdc}.

\section{\class{wxPrintDialogData}}\label{wxprintdialogdata}

This class holds information related to the visual characteristics of wxPrintDialog.
It contains a wxPrintData object with underlying printing settings.

\membersection{wxPrintDialogData::GetCollate}\label{wxprintdialogdatagetcollate}

\constfunc{bool}{GetCollate}{\void}

Returns true if the user requested that the document(s) be collated.


\membersection{wxPrintDialogData::GetFromPage}\label{wxprintdialogdatagetfrompage}

\constfunc{int}{GetFromPage}{\void}

Returns the {\it from} page number, as entered by the user.


\membersection{wxPrintDialogData::GetMaxPage}\label{wxprintdialogdatagetmaxpage}

\constfunc{int}{GetMaxPage}{\void}

Returns the {\it maximum} page number.


\membersection{wxPrintDialogData::GetMinPage}\label{wxprintdialogdatagetminpage}

\constfunc{int}{GetMinPage}{\void}

Returns the {\it minimum} page number.


\membersection{wxPrintDialogData::GetNoCopies}\label{wxprintdialogdatagetnocopies}

\constfunc{int}{GetNoCopies}{\void}

Returns the number of copies requested by the user.


\membersection{wxPrintDialogData::GetPrintData}\label{wxprintdialogdatagetprintdata}

\func{wxPrintData\&}{GetPrintData}{\void}

Returns a reference to the internal wxPrintData object.


\membersection{wxPrintDialogData::GetPrintToFile}\label{wxprintdialogdatagetprinttofile}

\constfunc{bool}{GetPrintToFile}{\void}

Returns true if the user has selected printing to a file.


\membersection{wxPrintDialogData::GetSelection}\label{wxprintdialogdatagetselection}

\constfunc{bool}{GetSelection}{\void}

Returns true if the user requested that the selection be printed (where 'selection' is
a concept specific to the application).


\membersection{wxPrintDialogData::GetToPage}\label{wxprintdialogdatagettopage}

\constfunc{int}{GetToPage}{\void}

Returns the {\it to} page number, as entered by the user.


\membersection{wxPrintDialogData::IsOk}\label{wxprintdialogdataisok}

\constfunc{bool}{IsOk}{\void}

Returns true if the print data is valid for using in print dialogs.

Sets the 'Print to file' checkbox to true or false.


\membersection{wxPrintDialogData::SetSelection}\label{wxprintdialogdatasetselection}

\func{void}{SetSelection}{\param{bool}{ flag}}

Selects the 'Selection' radio button. The effect of printing the selection depends on how the application
implements this command, if at all.


\membersection{wxPrintDialogData::SetSetupDialog}\label{wxprintdialogdatasetsetupdialog}

\func{void}{SetSetupDialog}{\param{bool }{flag}}

Determines whether the dialog to be shown will be the Print dialog
(pass false) or Print Setup dialog (pass true).

This function has been deprecated since version 2.5.4.

\section{\class{wxPrinter}}\label{wxprinter}

This class represents the Windows or PostScript printer, and is the vehicle through
which printing may be launched by an application. Printing can also
be achieved through using of lower functions and classes, but
this and associated classes provide a more convenient and general
method of printing.
