Constructor. Create instances dynamically near the start of your application after creating
a wxDocManager instance, and before doing any document or view operations.
{\it manager} is the document manager object which manages this template.
{\it descr} is a short description of what the template is for. This string will be displayed in the
file filter list of Windows file selectors.
{\it filter} is an appropriate file filter such as {\tt *.txt}.
{\it dir} is the default directory to use for file selectors.
{\it ext} is the default file extension (such as txt).
{\it docTypeName} is a name that should be unique for a given type of document, used for
gathering a list of views relevant to a particular document.
{\it viewTypeName} is a name that should be unique for a given view.
{\it docClassInfo} is a pointer to the run-time document class information as returned
by the CLASSINFO macro, e.g. CLASSINFO(MyDocumentClass). If this is not supplied,
you will need to derive a new wxDocTemplate class and override the CreateDocument
member to return a new document instance on demand.
{\it viewClassInfo} is a pointer to the run-time view class information as returned
by the CLASSINFO macro, e.g. CLASSINFO(MyViewClass). If this is not supplied,
you will need to derive a new wxDocTemplate class and override the CreateView
member to return a new view instance on demand.
{\it flags} is a bit list of the following:
\begin{itemize}\itemsep=0pt
\item wxTEMPLATE\_VISIBLE The template may be displayed to the user in dialogs.
\item wxTEMPLATE\_INVISIBLE The template may not be displayed to the user in dialogs.
\item wxDEFAULT\_TEMPLATE\_FLAGS Defined as wxTEMPLATE\_VISIBLE.
\end{itemize}
\perlnote{In wxPerl {\tt docClassInfo} and {\tt viewClassInfo} can be
either {\tt Wx::ClassInfo} objects or strings which contain the name
of the perl packages which are to be used as {\tt Wx::Document} and
{\tt Wx::View} classes (they must have a constructor named {\tt
new}):
\indented{2cm}{\begin{twocollist}
\twocolitem{{\bf Wx::DocTemplate->new( docmgr, descr, filter, dir,
ext, docTypeName, viewTypeName, docClassInfo, viewClassInfo, flags
)}}{ will construct document and view objects from the class information}
\twocolitem{{\bf Wx::DocTemplate->new( docmgr, descr, filter, dir,
ext, docTypeName, viewTypeName, docClassName, viewClassName, flags
)}}{ will construct document and view objects from perl packages}
\twocolitem{{\bf Wx::DocTemplate->new( docmgr, descr, filter, dir,
ext, docTypeName, viewTypeName )}}{
{\tt Wx::DocTemplate::CreateDocument()} and
{\tt Wx::DocTemplate::CreateView()} must be overridden}
\end{twocollist}}}
\membersection{wxDocTemplate::\destruct{wxDocTemplate}}\label{wxdoctemplatedtor}
\func{void}{\destruct{wxDocTemplate}}{\void}
Destructor.
\membersection{wxDocTemplate::CreateDocument}\label{wxdoctemplatecreatedocument}
\func{wxDocument *}{CreateDocument}{\param{const wxString\& }{path}, \param{long}{ flags = 0}}
Creates a new instance of the associated document class. If you have not supplied
a wxClassInfo parameter to the template constructor, you will need to override this
function to return an appropriate document instance.
This function calls wxDocTemplate::InitDocument which in turns
calls wxDocument::OnCreate.
\membersection{wxDocTemplate::CreateView}\label{wxdoctemplatecreateview}
\func{wxView *}{CreateView}{\param{wxDocument *}{doc}, \param{long}{ flags = 0}}
Creates a new instance of the associated view class. If you have not supplied
a wxClassInfo parameter to the template constructor, you will need to override this
function to return an appropriate view instance.
\membersection{wxDocTemplate::GetDefaultExtension}\label{wxdoctemplategetdefaultextension}
\func{wxString}{GetDefaultExtension}{\void}
Returns the default file extension for the document data, as passed to the document template constructor.
\membersection{wxDocTemplate::GetDescription}\label{wxdoctemplategetdescription}
\func{wxString}{GetDescription}{\void}
Returns the text description of this template, as passed to the document template constructor.
\membersection{wxDocTemplate::GetDirectory}\label{wxdoctemplategetdirectory}
\func{wxString}{GetDirectory}{\void}
Returns the default directory, as passed to the document template constructor.
\membersection{wxDocTemplate::GetDocumentManager}\label{wxdoctemplategetdocumentmanager}
\func{wxDocManager *}{GetDocumentManager}{\void}
Returns a pointer to the document manager instance for which this template was created.
\membersection{wxDocTemplate::GetDocumentName}\label{wxdoctemplategetdocumentname}
\func{wxString}{GetDocumentName}{\void}
Returns the document type name, as passed to the document template constructor.
\membersection{wxDocTemplate::GetFileFilter}\label{wxdoctemplategetfilefilter}
\func{wxString}{GetFileFilter}{\void}
Returns the file filter, as passed to the document template constructor.
\membersection{wxDocTemplate::GetFlags}\label{wxdoctemplategetflags}
\func{long}{GetFlags}{\void}
Returns the flags, as passed to the document template constructor.
\membersection{wxDocTemplate::GetViewName}\label{wxdoctemplategetviewname}
\func{wxString}{GetViewName}{\void}
Returns the view type name, as passed to the document template constructor.
\membersection{wxDocTemplate::InitDocument}\label{wxdoctemplateinitdocument}
\func{bool}{InitDocument}{\param{wxDocument* }{doc}, \param{const wxString\& }{path}, \param{long}{ flags = 0}}
Initialises the document, calling wxDocument::OnCreate. This is called from
wxDocTemplate::CreateDocument.
\membersection{wxDocTemplate::IsVisible}\label{wxdoctemplateisvisible}
\func{bool}{IsVisible}{\void}
Returns true if the document template can be shown in user dialogs, false otherwise.
\membersection{wxDocTemplate::SetDefaultExtension}\label{wxdoctemplatesetdefaultextension}
\func{void}{SetDefaultExtension}{\param{const wxString\& }{ext}}
Sets the default file extension.

\func{void}{SetDocumentManager}{\param{wxDocManager *}{manager}}
Sets the pointer to the document manager instance for which this template was created.
Should not be called by the application.
\membersection{wxDocTemplate::SetFileFilter}\label{wxdoctemplatesetfilefilter}
\func{void}{SetFileFilter}{\param{const wxString\& }{filter}}
Sets the file filter.
\membersection{wxDocTemplate::SetFlags}\label{wxdoctemplatesetflags}
\func{void}{SetFlags}{\param{long }{flags}}
Sets the internal document template flags (see the constructor description for more details).
