Destructor.
\membersection{wxPreviewCanvas::OnPaint}\label{wxpreviewcanvasonpaint}
\func{void}{OnPaint}{\param{wxPaintEvent\& }{event}}
Calls \helpref{wxPrintPreview::PaintPage}{wxprintpreviewpaintpage} to refresh the canvas.
\section{\class{wxPreviewControlBar}}\label{wxpreviewcontrolbar}
This is the default implementation of the preview control bar, a panel
with buttons and a zoom control. You can derive a new class from this and
override some or all member functions to change the behaviour and appearance;
or you can leave it as it is.

Constructor.
The buttons parameter may be a combination of the following, using the bitwise `or' operator.
\begin{twocollist}\itemsep=0pt
\twocolitem{wxPREVIEW\_PRINT}{Create a print button.}
\twocolitem{wxPREVIEW\_NEXT}{Create a next page button.}
\twocolitem{wxPREVIEW\_PREVIOUS}{Create a previous page button.}
\twocolitem{wxPREVIEW\_ZOOM}{Create a zoom control.}
\twocolitem{wxPREVIEW\_DEFAULT}{Equivalent to a combination of wxPREVIEW\_PREVIOUS, wxPREVIEW\_NEXT and
wxPREVIEW\_ZOOM.}

\func{}{\destruct{wxPreviewControlBar}}{\void}
Destructor.
\membersection{wxPreviewControlBar::CreateButtons}\label{wxpreviewcontrolbarcreatebuttons}
\func{void}{CreateButtons}{\void}
Creates buttons, according to value of the button style flags.
\membersection{wxPreviewControlBar::GetPrintPreview}\label{wxpreviewcontrolbargetprintpreview}
\func{wxPrintPreview *}{GetPrintPreview}{\void}
Gets the print preview object associated with the control bar.
\membersection{wxPreviewControlBar::GetZoomControl}\label{wxpreviewcontrolbargetzoomcontrol}
\func{int}{GetZoomControl}{\void}
Gets the current zoom setting in percent.
\membersection{wxPreviewControlBar::SetZoomControl}\label{wxpreviewcontrolbarsetzoomcontrol}
\func{void}{SetZoomControl}{\param{int }{percent}}
Sets the zoom control.
\section{\class{wxPreviewFrame}}\label{wxpreviewframe}
This class provides the default method of managing the print preview interface.
Member functions may be overridden to replace functionality, or the
class may be used without derivation.

\param{long}{ style = wxDEFAULT\_FRAME\_STYLE}, \param{const wxString\& }{name = ``frame"}}
Constructor. Pass a print preview object plus other normal frame arguments.
The print preview object will be destroyed by the frame when it closes.
\membersection{wxPreviewFrame::\destruct{wxPreviewFrame}}\label{wxpreviewframedtor}
\func{}{\destruct{wxPreviewFrame}}{\void}
Destructor.
\membersection{wxPreviewFrame::CreateControlBar}\label{wxpreviewframecreatecontrolbar}
\func{void}{CreateControlBar}{\void}
Creates a wxPreviewControlBar. Override this function to allow
a user-defined preview control bar object to be created.
\membersection{wxPreviewFrame::CreateCanvas}\label{wxpreviewframecreatecanvas}
\func{void}{CreateCanvas}{\void}
Creates a wxPreviewCanvas. Override this function to allow
a user-defined preview canvas object to be created.
\membersection{wxPreviewFrame::Initialize}\label{wxpreviewframeinitialize}
\func{void}{Initialize}{\void}
Creates the preview canvas and control bar, and calls
wxWindow::MakeModal(true) to disable other top-level windows
in the application.
This function should be called by the application prior to
showing the frame.
\membersection{wxPreviewFrame::OnCloseWindow}\label{wxpreviewframeonclosewindow}
\func{void}{OnCloseWindow}{\param{wxCloseEvent\&}{ event}}
Enables the other frames in the application, and deletes the print preview
object, implicitly deleting any printout objects associated with the print
preview object.
