## Constructor & Destructor Documentation

wxDocTemplate::wxDocTemplate | ( | wxDocManager * | manager,
|  | const wxString & | descr,
|  | const wxString & | filter,
|  | const wxString & | dir,
|  | const wxString & | ext,
|  | const wxString & | docTypeName,
|  | const wxString & | viewTypeName,
|  | wxClassInfo * | docClassInfo = `0`,
|  | wxClassInfo * | viewClassInfo = `0`,
|  | long | flags = `wxTEMPLATE_VISIBLE`
| ) |  |

Constructor.

Create instances dynamically near the start of your application after creating a wxDocManager instance, and before doing any document or view operations.

Parameters

  manager | The document manager object which manages this template.
  descr | A short description of what the template is for. This string will be displayed in the file filter list of Windows file selectors.
  filter | An appropriate file filter such as "*.txt".
  dir | The default directory to use for file selectors.
  ext | The default file extension (such as "txt").
  docTypeName | A name that should be unique for a given type of document, used for gathering a list of views relevant to a particular document.
  viewTypeName | A name that should be unique for a given view.
  docClassInfo | A pointer to the run-time document class information as returned by the wxCLASSINFO() macro, e.g. wxCLASSINFO(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.
  viewClassInfo | A pointer to the run-time view class information as returned by the wxCLASSINFO() macro, e.g. wxCLASSINFO(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.
  flags | A bit list of the following: wxTEMPLATE_VISIBLE - The template may be displayed to the user in dialogs. wxTEMPLATE_INVISIBLE - The template may not be displayed to the user in dialogs. wxDEFAULT_TEMPLATE_FLAGS - Defined as wxTEMPLATE_VISIBLE.

wxPerl Note:

In wxPerl docClassInfo and viewClassInfo can be either `Wx::ClassInfo` objects or strings containing the name of the perl packages which are to be used as `Wx::Document` and `Wx::View` classes (they must have a constructor named new); as an example:

- Wx::DocTemplate->new(docmgr, descr, filter, dir, ext, docTypeName, viewTypeName, docClassInfo, viewClassInfo, flags): will construct document and view objects from the class information.
- Wx::DocTemplate->new(docmgr, descr, filter, dir, ext, docTypeName, viewTypeName, docClassName, viewClassName, flags): will construct document and view objects from perl packages.
- Wx::DocTemplate->new(docmgr, descr, filter, dir, ext, docTypeName, viewTypeName): in this case `Wx::DocTemplate::CreateDocument()` and `Wx::DocTemplate::CreateView()` must be overridden

virtual wxDocTemplate::~wxDocTemplate | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

virtual wxDocument* wxDocTemplate::CreateDocument | ( | const wxString & | path,
|  | long | flags = `0`
| ) |  |
| virtual

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 InitDocument() which in turns calls wxDocument::OnCreate().

virtual wxView* wxDocTemplate::CreateView | ( | wxDocument * | doc,
|  | long | flags = `0`
| ) |  |
| virtual

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.

If the new view initialization fails, it must call wxDocument::RemoveView() for consistency with the default behaviour of this function.

virtual bool wxDocTemplate::FileMatchesTemplate | ( | const wxString & | path | ) |
| virtual

This function implements the default (very primitive) format detection which checks if the extension is that of the template.

Parameters

  path | The path to be checked against the template.

wxString wxDocTemplate::GetDefaultExtension | ( |  | ) | const

Returns the default file extension for the document data, as passed to the document template constructor.

wxString wxDocTemplate::GetDescription | ( |  | ) | const

Returns the text description of this template, as passed to the document template constructor.

wxString wxDocTemplate::GetDirectory | ( |  | ) | const

Returns the default directory, as passed to the document template constructor.

wxClassInfo* wxDocTemplate::GetDocClassInfo | ( |  | ) | const

Returns the run-time class information that allows document instances to be constructed dynamically, as passed to the document template constructor.

wxDocManager* wxDocTemplate::GetDocumentManager | ( |  | ) | const

Returns a pointer to the document manager instance for which this template was created.

virtual wxString wxDocTemplate::GetDocumentName | ( |  | ) | const
| virtual

Returns the document type name, as passed to the document template constructor.

wxString wxDocTemplate::GetFileFilter | ( |  | ) | const

Returns the file filter, as passed to the document template constructor.

long wxDocTemplate::GetFlags | ( |  | ) | const

Returns the flags, as passed to the document template constructor.

wxPageSetupDialogData& wxDocTemplate::GetPageSetupDialogData | ( |  | ) |

Returns a reference to the wxPageSetupDialogData associated with the printing operations of this document manager.

const wxPageSetupDialogData& wxDocTemplate::GetPageSetupDialogData | ( |  | ) | const

Returns a reference to the wxPageSetupDialogData associated with the printing operations of this document manager.

wxClassInfo* wxDocTemplate::GetViewClassInfo | ( |  | ) | const

Returns the run-time class information that allows view instances to be constructed dynamically, as passed to the document template constructor.

virtual wxString wxDocTemplate::GetViewName | ( |  | ) | const
| virtual

Returns the view type name, as passed to the document template constructor.

virtual bool wxDocTemplate::InitDocument | ( | wxDocument * | doc,
|  | const wxString & | path,
|  | long | flags = `0`
| ) |  |
| virtual

Initialises the document, calling wxDocument::OnCreate().

This is called from CreateDocument().

If you override this method, notice that you must delete the doc if its initialization fails for consistency with the default behaviour.

Parameters

  doc | The document to initialize.
  path | The associated file path.
  flags | Flags passed to CreateDocument().

Returns
  true if the initialization was successful or false if it failed in which case doc should be deleted by this function.

bool wxDocTemplate::IsVisible | ( |  | ) | const

Returns true if the document template can be shown in user dialogs, false otherwise.

void wxDocTemplate::SetDefaultExtension | ( | const wxString & | ext | ) |

Sets the default file extension.

void wxDocTemplate::SetDescription | ( | const wxString & | descr | ) |

Sets the template description.

void wxDocTemplate::SetDirectory | ( | const wxString & | dir | ) |

Sets the default directory.

void wxDocTemplate::SetDocumentManager | ( | wxDocManager * | manager | ) |

Sets the pointer to the document manager instance for which this template was created.

Should not be called by the application.

void wxDocTemplate::SetFileFilter | ( | const wxString & | filter | ) |

Sets the file filter.

void wxDocTemplate::SetFlags | ( | long | flags | ) |

Sets the internal document template flags (see the constructor description for more details).
