+ Inheritance diagram for wxDocument:

Detailed Description

The document class can be used to model an application's file-based data.

It is part of the document/view framework supported by wxWidgets, and cooperates with the wxView, wxDocTemplate and wxDocManager classes.

A normal document is the one created without parent document and is associated with a disk file. Since version 2.9.2 wxWidgets also supports a special kind of documents called child documents which are virtual in the sense that they do not correspond to a file but rather to a part of their parent document. Because of this, the child documents can't be created directly by user but can only be created by the parent document (usually when it's being created itself). They also can't be independently saved. A child document has its own view with the corresponding window. This view can be closed by user but, importantly, is also automatically closed when its parent document is closed. Thus, child documents may be convenient for creating additional windows which need to be closed when the main document is. The docview sample demonstrates this use of child documents by creating a child document containing the information about the parameters of the image opened in the main document.

Constructor & Destructor Documentation

wxDocument::wxDocument ( wxDocument parent = NULL)

Constructor.

Define your own default constructor to initialize application-specific data.

Parameters
parentSpecifying a non-NULL parent document here makes this document a special child document, see their description in the class documentation. Notice that this parameter exists but is ignored in wxWidgets versions prior to 2.9.1.
virtual wxDocument::~wxDocument ( )
virtual

Destructor.

Removes itself from the document manager.

Member Function Documentation

void wxDocument::Activate ( ) const

Activate the first view of the document if any.

This function simply calls the Raise() method of the frame of the first view. You may need to override the Raise() method to get the desired effect if you are not using a standard wxFrame for your view. For instance, if your document is inside its own notebook tab you could implement Raise() like this:

void MyNotebookPage::Raise()
{
wxNotebook* notebook = wxStaticCast(GetParent(), wxNotebook);
notebook->SetSelection(notebook->FindPage(this));
}
See also
GetFirstView()
Since
2.9.5
virtual bool wxDocument::AddView ( wxView view)
virtual

If the view is not already in the list of views, adds the view and calls OnChangedViewList().

bool wxDocument::AlreadySaved ( ) const

Returns true if the document hasn't been modified since the last time it had been saved.

Notice that this function returns false if the document had been never saved at all, so it may be also used to test whether it makes sense to save the document: if it returns true, there is nothing to save but if false is returned, it can be saved, even if it might be not modified (this can be used to create an empty document file by the user).

See also
IsModified(), GetDocumentSaved()
Since
2.9.0
virtual bool wxDocument::Close ( )
virtual

Closes the document, by calling OnSaveModified() and then (if this returned true) OnCloseDocument().

This does not normally delete the document object, use DeleteAllViews() to do this implicitly.

virtual bool wxDocument::DeleteAllViews ( )
virtual

Calls wxView::Close() and deletes each view.

Deleting the final view will implicitly delete the document itself, because the wxView destructor calls RemoveView(). This in turns calls OnChangedViewList(), whose default implementation is to save and delete the document if no views exist.

virtual bool wxDocument::DeleteContents ( )
virtual

Virtual method called from OnCloseDocument().

This method may be overridden to perform any additional cleanup which might be needed when the document is closed.

The return value of this method is currently ignored.

The default version does nothing and simply returns true.

virtual bool wxDocument::DoOpenDocument ( const wxString file)
protectedvirtual

This method is called by OnOpenDocument() to really load the document contents from the specified file.

Base class version creates a file-based stream and calls LoadObject(). Override this if you need to do something else or prefer not to use LoadObject() at all.

virtual bool wxDocument::DoSaveDocument ( const wxString file)
protectedvirtual

This method is called by OnSaveDocument() to really save the document contents to the specified file.

Base class version creates a file-based stream and calls SaveObject(). Override this if you need to do something else or prefer not to use SaveObject() at all.

virtual wxCommandProcessor* wxDocument::GetCommandProcessor ( ) const
virtual

Returns a pointer to the command processor associated with this document.

See also
wxCommandProcessor
virtual wxDocManager* wxDocument::GetDocumentManager ( ) const
virtual

Gets a pointer to the associated document manager.

wxString wxDocument::GetDocumentName ( ) const

Gets the document type name for this document.

See the comment for m_documentTypeName.

bool wxDocument::GetDocumentSaved ( ) const

Return true if this document had been already saved.

See also
IsModified()
virtual wxDocTemplate* wxDocument::GetDocumentTemplate ( ) const
virtual

Gets a pointer to the template that created the document.

virtual wxWindow* wxDocument::GetDocumentWindow ( ) const
virtual

Intended to return a suitable window for using as a parent for document-related dialog boxes.

By default, uses the frame associated with the first view.

wxString wxDocument::GetFilename ( ) const

Gets the filename associated with this document, or "" if none is associated.

wxView* wxDocument::GetFirstView ( ) const

A convenience function to get the first view for a document, because in many cases a document will only have a single view.

See also
GetViews()
wxString wxDocument::GetTitle ( ) const

Gets the title for this document.

The document title is used for an associated frame (if any), and is usually constructed by the framework from the filename.

virtual wxString wxDocument::GetUserReadableName ( ) const
virtual

Return the document name suitable to be shown to the user.

The default implementation uses the document title, if any, of the name part of the document filename if it was set or, otherwise, the string unnamed.

wxList& wxDocument::GetViews ( )

Returns the list whose elements are the views on the document.

See also
GetFirstView()
const wxList& wxDocument::GetViews ( ) const

Returns the list whose elements are the views on the document.

See also
GetFirstView()
wxViewVector wxDocument::GetViewsVector ( ) const

Returns a vector of wxView pointers.

Since
2.9.5
bool wxDocument::IsChildDocument ( ) const

Returns true if this document is a child document corresponding to a part of the parent document and not a disk file as usual.

This method can be used to check whether file-related operations make sense for this document as they only apply to top-level documents and not child ones.

Since
2.9.2
virtual bool wxDocument::IsModified ( ) const
virtual

Returns true if the document has been modified since the last save, false otherwise.

You may need to override this if your document view maintains its own record of being modified.

See also
Modify()
virtual istream& wxDocument::LoadObject ( istream &  stream)
virtual

Override this function and call it from your own LoadObject() before streaming your own data.

LoadObject() is called by the framework automatically when the document contents need to be loaded.

Note
This version of LoadObject() may not exist depending on how wxWidgets was configured.
virtual wxInputStream& wxDocument::LoadObject ( wxInputStream stream)
virtual

Override this function and call it from your own LoadObject() before streaming your own data.

LoadObject() is called by the framework automatically when the document contents need to be loaded.

Note
This version of LoadObject() may not exist depending on how wxWidgets was configured.
virtual void wxDocument::Modify ( bool  modify)
virtual

Call with true to mark the document as modified since the last save, false otherwise.

You may need to override this if your document view maintains its own record of being modified.

See also
IsModified()
virtual void wxDocument::OnChangedViewList ( )
virtual

Called when a view is added to or deleted from this document.

The default implementation saves and deletes the document if no views exist (the last one has just been removed).

virtual void wxDocument::OnChangeFilename ( bool  notifyViews)
virtual

If notifyViews is true, wxView::OnChangeFilename() is called for all views.

Since
2.9.0
virtual bool wxDocument::OnCloseDocument ( )
virtual

This virtual function is called when the document is being closed.

The default implementation calls DeleteContents() (which may be overridden to perform additional cleanup) and sets the modified flag to false. You can override it to supply additional behaviour when the document is closed with Close().

Notice that previous wxWidgets versions used to call this function also from OnNewDocument(), rather counter-intuitively. This is no longer the case since wxWidgets 2.9.0.

virtual bool wxDocument::OnCreate ( const wxString path,
long  flags 
)
virtual

Called just after the document object is created to give it a chance to initialize itself.

The default implementation uses the template associated with the document to create an initial view.

For compatibility reasons, this method may either delete the document itself if its initialization fails or not do it in which case it is deleted by caller. It is recommended to delete the document explicitly in this function if it can't be initialized.

Parameters
pathThe associated file path.
flagsFlags passed to CreateDocument().
Returns
true if the initialization was successful or false if it failed.
virtual wxCommandProcessor* wxDocument::OnCreateCommandProcessor ( )
virtual

Override this function if you want a different (or no) command processor to be created when the document is created.

By default, it returns an instance of wxCommandProcessor.

See also
wxCommandProcessor
virtual bool wxDocument::OnNewDocument ( )
virtual

The default implementation calls OnSaveModified() and DeleteContents(), makes a default title for the document, and notifies the views that the filename (in fact, the title) has changed.

virtual bool wxDocument::OnOpenDocument ( const wxString filename)
virtual

Constructs an input file stream for the given filename (which must not be empty), and calls LoadObject().

If LoadObject() returns true, the document is set to unmodified; otherwise, an error message box is displayed. The document's views are notified that the filename has changed, to give windows an opportunity to update their titles. All of the document's views are then updated.

virtual bool wxDocument::OnSaveDocument ( const wxString filename)
virtual

Constructs an output file stream for the given filename (which must not be empty), and calls SaveObject().

If SaveObject() returns true, the document is set to unmodified; otherwise, an error message box is displayed.

virtual bool wxDocument::OnSaveModified ( )
virtual

If the document has been modified, prompts the user to ask if the changes should be saved.

If the user replies Yes, the Save() function is called. If No, the document is marked as unmodified and the function succeeds. If Cancel, the function fails.

virtual bool wxDocument::RemoveView ( wxView view)
virtual

Removes the view from the document's list of views, and calls OnChangedViewList().

virtual bool wxDocument::Revert ( )
virtual

Discard changes and load last saved version.

Prompts the user first, and then calls DoOpenDocument() to reload the current file.

virtual bool wxDocument::Save ( )
virtual

Saves the document by calling OnSaveDocument() if there is an associated filename, or SaveAs() if there is no filename.

virtual bool wxDocument::SaveAs ( )
virtual

Prompts the user for a file to save to, and then calls OnSaveDocument().

virtual ostream& wxDocument::SaveObject ( ostream &  stream)
virtual

Override this function and call it from your own SaveObject() before streaming your own data.

SaveObject() is called by the framework automatically when the document contents need to be saved.

Note
This version of SaveObject() may not exist depending on how wxWidgets was configured.
virtual wxOutputStream& wxDocument::SaveObject ( wxOutputStream stream)
virtual

Override this function and call it from your own SaveObject() before streaming your own data.

SaveObject() is called by the framework automatically when the document contents need to be saved.

Note
This version of SaveObject() may not exist depending on how wxWidgets was configured.
virtual void wxDocument::SetCommandProcessor ( wxCommandProcessor processor)
virtual

Sets the command processor to be used for this document.

The document will then be responsible for its deletion. Normally you should not call this; override OnCreateCommandProcessor() instead.

See also
wxCommandProcessor
void wxDocument::SetDocumentName ( const wxString name)

Sets the document type name for this document.

See the comment for m_documentTypeName.

void wxDocument::SetDocumentSaved ( bool  saved = true)

Sets if this document has been already saved or not.

Normally there is no need to call this function as the document-view framework does it itself as the documents are loaded from and saved to the files. However it may be useful in some particular cases, for example it may be called with false argument to prevent the user from saving the just opened document into the same file if this shouldn't be done for some reason (e.g. file format version changes and a new extension should be used for saving).

See also
GetDocumentSaved(), AlreadySaved()
virtual void wxDocument::SetDocumentTemplate ( wxDocTemplate templ)
virtual

Sets the pointer to the template that created the document.

Should only be called by the framework.

void wxDocument::SetFilename ( const wxString filename,
bool  notifyViews = false 
)

Sets the filename for this document.

Usually called by the framework.

Calls OnChangeFilename() which in turn calls wxView::OnChangeFilename() for all views if notifyViews is true.

void wxDocument::SetTitle ( const wxString title)

Sets the title for this document.

The document title is used for an associated frame (if any), and is usually constructed by the framework from the filename.

virtual void wxDocument::UpdateAllViews ( wxView sender = NULL,
wxObject hint = NULL 
)
virtual

Updates all views.

If sender is non-NULL, does not update this view. hint represents optional information to allow a view to optimize its update.
