Constructor & Destructor Documentation

wxDocManager::wxDocManager ( long  flags = 0,
bool  initialize = true 
)

Constructor.

Create a document manager instance dynamically near the start of your application before doing any document or view operations.

If initialize is true, the Initialize() function will be called to create a default history list object. If you derive from wxDocManager, you may wish to call the base constructor with false, and then call Initialize() in your own constructor, to allow your own Initialize() or OnCreateFileHistory functions to be called.

Parameters
flagsCurrently unused.
initializeIndicates whether Initialize() should be called by this ctor.
virtual wxDocManager::~wxDocManager ( )
virtual

Destructor.

Member Function Documentation

virtual void wxDocManager::ActivateView ( wxView doc,
bool  activate = true 
)
virtual

Sets the current view.

void wxDocManager::AddDocument ( wxDocument doc)

Adds the document to the list of documents.

virtual void wxDocManager::AddFileToHistory ( const wxString filename)
virtual

Adds a file to the file history list, if we have a pointer to an appropriate file menu.

void wxDocManager::AssociateTemplate ( wxDocTemplate temp)

Adds the template to the document manager's template list.

bool wxDocManager::CloseDocument ( wxDocument doc,
bool  force = false 
)

Closes the specified document.

If force is true, the document is closed even if it has unsaved changes.

Parameters
docThe document to close, must be non-NULL.
forceIf true, close the document even if wxDocument::Close() returns false.
Returns
true if the document was closed or false if closing it was cancelled by user (only in force = false case).
bool wxDocManager::CloseDocuments ( bool  force = true)

Closes all currently opened documents.

See also
CloseDocument()
virtual wxDocument* wxDocManager::CreateDocument ( const wxString path,
long  flags = 0 
)
virtual

Creates a new document.

This function can either create a document corresponding to a new file or to an already existing one depending on whether wxDOC_NEW is specified in the flags.

By default, this function asks the user for the type of document to open and the path to its file if it's not specified, i.e. if path is empty. Specifying wxDOC_SILENT flag suppresses any prompts and means that the path must be non-empty and there must be a registered document template handling the extension of this file, otherwise a warning message is logged and the function returns NULL. Notice that wxDOC_SILENT can be combined with wxDOC_NEW, however in this case the path must still be specified, even if the file with this path typically won't exist.

Finally notice that if this document manager was configured to allow only a limited number of simultaneously opened documents using SetMaxDocsOpen(), this function will try to close the oldest existing document if this number was reached before creating a new document. And if closing the old document fails (e.g. because it was vetoed by user), this function fails as well.

Parameters
pathPath to a file or an empty string. If the path is empty, the user will be asked to select it (thus, this is incompatible with the use of wxDOC_SILENT). The file should exist unless flags includes wxDOC_NEW.
flagsBy default, none. May include wxDOC_NEW to indicate that the new document corresponds to a new file and not an existing one and wxDOC_SILENT to suppress any dialogs asking the user about the file path and type.
Returns
a new document object or NULL on failure.
wxDocument* wxDocManager::CreateNewDocument ( )

Creates an empty new document.

This is equivalent to calling CreateDocument() with wxDOC_NEW flags and without the file name.

virtual wxPreviewFrame* wxDocManager::CreatePreviewFrame ( wxPrintPreviewBase *  preview,
wxWindow parent,
const wxString title 
)
protectedvirtual

Create the frame used for print preview.

This method can be overridden if you need to change the behaviour or appearance of the preview window. By default, a standard wxPreviewFrame is created.

Since
2.9.1
Parameters
previewThe associated preview object.
parentThe parent window for the frame.
titleThe suggested title for the print preview frame.
Returns
A new print preview frame, must not return NULL.
virtual wxView* wxDocManager::CreateView ( wxDocument doc,
long  flags = 0 
)
virtual

Creates a new view for the given document.

If more than one view is allowed for the document (by virtue of multiple templates mentioning the same document type), a choice of view is presented to the user.

void wxDocManager::DisassociateTemplate ( wxDocTemplate temp)

Removes the template from the list of templates.

virtual void wxDocManager::FileHistoryAddFilesToMenu ( )
virtual

Appends the files in the history list to all menus managed by the file history object.

virtual void wxDocManager::FileHistoryAddFilesToMenu ( wxMenu menu)
virtual

Appends the files in the history list to the given menu only.

virtual void wxDocManager::FileHistoryLoad ( const wxConfigBase config)
virtual

Loads the file history from a config object.

See also
wxConfigBase
virtual void wxDocManager::FileHistoryRemoveMenu ( wxMenu menu)
virtual

Removes the given menu from the list of menus managed by the file history object.

virtual void wxDocManager::FileHistorySave ( wxConfigBase resourceFile)
virtual

Saves the file history into a config object.

This must be called explicitly by the application.

See also
wxConfigBase
virtual void wxDocManager::FileHistoryUseMenu ( wxMenu menu)
virtual

Use this menu for appending recently-visited document filenames, for convenient access.

Calling this function with a valid menu pointer enables the history list functionality.

Note
You can add multiple menus using this function, to be managed by the file history object.
wxDocument* wxDocManager::FindDocumentByPath ( const wxString path) const

Search for the document corresponding to the given file.

Parameters
pathDocument file path.
Returns
Pointer to a wxDocument, or NULL if none found.
Since
2.9.5
wxDocTemplate* wxDocManager::FindTemplate ( const wxClassInfo classinfo)

Search for a particular document template.

Example:

// creating a document instance of the specified document type:
m_doc = (MyDoc*)docManager->FindTemplate(CLASSINFO(MyDoc))->
CreateDocument(wxEmptyString, wxDOC_SILENT);
Parameters
classinfoClass info of a document class for which a wxDocTemplate had been previously created.
Returns
Pointer to a wxDocTemplate, or NULL if none found.
Since
2.9.2
virtual wxDocTemplate* wxDocManager::FindTemplateForPath ( const wxString path)
virtual

Given a path, try to find template that matches the extension.

This is only an approximate method of finding a template for creating a document.

wxView* wxDocManager::GetAnyUsableView ( ) const

Returns the view to apply a user command to.

This method tries to find the view that the user wants to interact with. It returns the same view as GetCurrentDocument() if there is any currently active view but falls back to the first view of the first document if there is no active view.

Since
2.9.5
wxDocument* wxDocManager::GetCurrentDocument ( ) const

Returns the document associated with the currently active view (if any).

virtual wxView* wxDocManager::GetCurrentView ( ) const
virtual

Returns the currently active view.

This method can return NULL if no view is currently active.

See also
GetAnyUsableView()
wxList& wxDocManager::GetDocuments ( )

Returns a reference to the list of documents.

wxDocVector wxDocManager::GetDocumentsVector ( ) const

Returns a vector of wxDocument pointers.

Since
2.9.5
virtual wxFileHistory* wxDocManager::GetFileHistory ( ) const
virtual

Returns a pointer to file history.

virtual size_t wxDocManager::GetHistoryFilesCount ( ) const
virtual

Returns the number of files currently stored in the file history.

wxString wxDocManager::GetLastDirectory ( ) const

Returns the directory last selected by the user when opening a file.

Initially empty.

int wxDocManager::GetMaxDocsOpen ( ) const

Returns the number of documents that can be open simultaneously.

wxList& wxDocManager::GetTemplates ( )

Returns a reference to the list of associated templates.

wxDocTemplateVector wxDocManager::GetTemplatesVector ( ) const

Returns a vector of wxDocTemplate pointers.

Since
2.9.5
virtual bool wxDocManager::Initialize ( )
virtual

Initializes data; currently just calls OnCreateFileHistory().

Some data cannot always be initialized in the constructor because the programmer must be given the opportunity to override functionality. If OnCreateFileHistory() was called from the constructor, an overridden virtual OnCreateFileHistory() would not be called due to C++'s 'interesting' constructor semantics. In fact Initialize() is called from the wxDocManager constructor, but this can be vetoed by passing false to the second argument, allowing the derived class's constructor to call Initialize(), possibly calling a different OnCreateFileHistory() from the default.

The bottom line: if you're not deriving from Initialize(), forget it and construct wxDocManager with no arguments.

virtual wxString wxDocManager::MakeNewDocumentName ( )
virtual

Return a string containing a suitable default name for a new document.

By default this is implemented by appending an integer counter to the string unnamed but can be overridden in the derived classes to do something more appropriate.

virtual wxFileHistory* wxDocManager::OnCreateFileHistory ( )
virtual

A hook to allow a derived class to create a different type of file history.

Called from Initialize().

void wxDocManager::OnFileClose ( wxCommandEvent event)

Closes and deletes the currently active document.

void wxDocManager::OnFileCloseAll ( wxCommandEvent event)

Closes and deletes all the currently opened documents.

void wxDocManager::OnFileNew ( wxCommandEvent event)

Creates a document from a list of templates (if more than one template).

void wxDocManager::OnFileOpen ( wxCommandEvent event)

Creates a new document and reads in the selected file.

void wxDocManager::OnFileRevert ( wxCommandEvent event)

Reverts the current document by calling wxDocument::Revert() for the current document.

void wxDocManager::OnFileSave ( wxCommandEvent event)

Saves the current document by calling wxDocument::Save() for the current document.

void wxDocManager::OnFileSaveAs ( wxCommandEvent event)

Calls wxDocument::SaveAs() for the current document.

virtual void wxDocManager::OnMRUFileNotExist ( unsigned  n,
const wxString filename 
)
protectedvirtual

Called when a file selected from the MRU list doesn't exist any more.

The default behaviour is to remove the file from the MRU (most recently used) files list and the corresponding menu and notify the user about it but this method can be overridden to customize it.

For example, an application may want to just give an error about the missing file filename but not remove it from the file history. Or it could ask the user whether the file should be kept or removed.

Notice that this method is called only if the file selected by user from the MRU files in the menu doesn't exist, but not if opening it failed for any other reason because in the latter case the default behaviour of removing the file from the MRU list is inappropriate. If you still want to do it, you would need to do it by calling RemoveFileFromHistory() explicitly in the part of the file opening code that may fail.

Since
2.9.3
Parameters
nThe index of the file in the MRU list, it can be passed to RemoveFileFromHistory() to remove this file from the list.
filenameThe full name of the file.
void wxDocManager::RemoveDocument ( wxDocument doc)

Removes the document from the list of documents.

virtual wxDocTemplate* wxDocManager::SelectDocumentPath ( wxDocTemplate **  templates,
int  noTemplates,
wxString path,
long  flags,
bool  save = false 
)
virtual

Under Windows, pops up a file selector with a list of filters corresponding to document templates.

The wxDocTemplate corresponding to the selected file's extension is returned.

On other platforms, if there is more than one document template a choice list is popped up, followed by a file selector.

This function is used in CreateDocument().

wxPerl Note: In wxPerl templates is a reference to a list of templates. If you override this method in your document manager it must return two values, e.g.:

(doctemplate, path) = My::DocManager->SelectDocumentPath(...);
virtual wxDocTemplate* wxDocManager::SelectDocumentType ( wxDocTemplate **  templates,
int  noTemplates,
bool  sort = false 
)
virtual

Returns a document template by asking the user (if there is more than one template).

This function is used in CreateDocument().

Parameters
templatesPointer to an array of templates from which to choose a desired template.
noTemplatesNumber of templates being pointed to by the templates pointer.
sortIf more than one template is passed into templates, then this parameter indicates whether the list of templates that the user will have to choose from is sorted or not when shown the choice box dialog. Default is false.

wxPerl Note: In wxPerl templates is a reference to a list of templates.

virtual wxDocTemplate* wxDocManager::SelectViewType ( wxDocTemplate **  templates,
int  noTemplates,
bool  sort = false 
)
virtual

Returns a document template by asking the user (if there is more than one template), displaying a list of valid views.

This function is used in CreateView(). The dialog normally will not appear because the array of templates only contains those relevant to the document in question, and often there will only be one such.

Parameters
templatesPointer to an array of templates from which to choose a desired template.
noTemplatesNumber of templates being pointed to by the templates pointer.
sortIf more than one template is passed into templates, then this parameter indicates whether the list of templates that the user will have to choose from is sorted or not when shown the choice box dialog. Default is false.

wxPerl Note: In wxPerl templates is a reference to a list of templates.

void wxDocManager::SetLastDirectory ( const wxString dir)

Sets the directory to be displayed to the user when opening a file.

Initially this is empty.

void wxDocManager::SetMaxDocsOpen ( int  n)

Sets the maximum number of documents that can be open at a time.

By default, this is INT_MAX, i.e. the number of documents is unlimited. If you set it to 1, existing documents will be saved and deleted when the user tries to open or create a new one (similar to the behaviour of Windows Write, for example). Allowing multiple documents gives behaviour more akin to MS Word and other Multiple Document Interface applications.
