Detailed Description

An abstract base class, TDocument is the base class for all document objects and serves as an interface between the document, its views, and the document manager (TDocManager class).

TDocument creates, destroys, and sends messages about the view. For example, if the user changes a document, TDocument tells the view that the document has been updated. The DEFINE_DOC_TEMPLATE_CLASS macro associates a document with its views.

In order to send messages to its associated views, the document maintains a list of all the views existing for that document and communicates with the views using ObjectWindows event-handling mechanism. Rather than using the function SendMessage(), the document accesses the view's event table. The views can update the document's data by calling the member functions of the particular document. Views can also request streams, which are constructed by the document.

Both documents and views have lists of properties for their applications to use. When documents and views are created or destroyed, messages are sent to the application, which can then query the properties to determine how to process the document or view. It is the document manager's responsibility to determine if a particular view is appropriate for the given document.

Because the property attribute functions are virtual, a derived class (which is called first) might override the properties defined in a base class. Each derived class must implement its own property attribute types of either string or binary data. If the derived class duplicates the property names of the parent class, it should provide the same behavior and data type as the parent.

In order to add persistence to documents, TDocument contains several virtual functions (for example, InStream and OutStream) that support streaming. Your derived classes need to override these functions in order to read and write data.

Although documents are usually associated with files, they do not necessarily have to be files; they can also consist of database tables, mail systems, fax or modem transmissions, disk directories, and so on.

Member Typedef Documentation

◆ List

typedef TList owl::TDocument::List

Definition at line 223 of file docview.h.

Member Enumeration Documentation

◆ TDocProp

enum owl::TDocument::TDocProp

These property values, which describe the basic properties of a document, are available in classes derived from TDocument.

They can be used to update and query the attributes of a document. PrevProperty and NextProperty are delimiters for every document's property list. See GetProperty() and SetProperty() for more information.

Enumerator
PrevProperty	Index of last property in base class (none in this case)
DocumentClass	text Property: Name of C++ class encapsulating document
TemplateName	text property: Name of template attached to document
ViewCount	int property: Number of views displaying this document
StoragePath	text property: Identifies object holding data of this document
DocTitle	text property: Caption of this document
NextProperty	Next index to be used by derived class.

Definition at line 193 of file docview.h.

Constructor & Destructor Documentation

◆ TDocument() [1/2]

owl::TDocument::TDocument ( TDocument * parent = 0 )

Although you do not create a TDocument object directly, you must call the constructor when you create a derived class.

parent points to the parent of the new document. If no parent exists, parent is 0.

Definition at line 34 of file document.cpp.

References CHECK, owl::TAppDictionary::GetApplication(), owl::TDocument::TList::Insert(), owl::OWLGetAppDictionary(), and owl::TXOwl::Raise().

◆ ~TDocument()

owl::TDocument::~TDocument ( )

virtual

Deletes a TDocument object.

Normally, Close is called first. TDocument's destructor destroys all children and closes all open streams. If this is the last document that used the template, it closes the object's template and any associated views, deletes the object's stream, and removes itself from the parent's list of children if a parent exists. If there is no parent, it removes itself from the document manager's document list.

Definition at line 80 of file document.cpp.

References _T, DestroyChildren(), DestroyViews(), owl::dnClose, owl::TDocManager::PostEvent(), owl::TDocument::TList::Remove(), SetTemplate(), TRACEX, and WARN.

◆ TDocument() [2/2]

owl::TDocument::TDocument ( TDocManager * docMan )

inline

create a dummy document to hold docmgr

Create a dummy document to hold docmgr.

Definition at line 975 of file docview.h.

Member Function Documentation

◆ AttachStream()

void owl::TDocument::AttachStream ( TStream & strm )

protectedvirtual

called from TStream constructor

Called from TStream's constructor, AttachStream attaches a stream to the current document.

Definition at line 441 of file document.cpp.

References owl::TStream::NextStream.

◆ CanClose()

bool owl::TDocument::CanClose ( )

virtual

Returns false if unable to close.

Checks to see if all child documents can be closed before closing the current document.

If any child returns false, CanClose returns false and aborts the process. If all children return true, calls TDocManager::FlushDoc. If FlushDoc finds that the document has been changed but not saved, it displays a message asking the user to either save the document, discard any changes, or cancel the operation. If the document has not been changed and all children's CanClose functions return true, this CanClose function returns true.

Reimplemented in ocf::TOleDocument.

Definition at line 775 of file document.cpp.

References owl::TDocManager::FlushDoc(), and owl::TDocument::TList::Next().

◆ Close()

bool owl::TDocument::Close ( )

virtual

close document, does not delete or detach

Closes the document but does not delete or detach the document.

Before closing the document, Close checks any child documents and tries to close them before closing the parent document. Even if you write your own Close function, call TDocument's version to ensure that all child documents are checked before the parent document is closed.

Reimplemented in ocf::TOleDocument, ocf::TStorageDocument, and owl::TFileDocument.

Definition at line 793 of file document.cpp.

References owl::TDocument::TList::Next().

◆ Commit()

bool owl::TDocument::Commit ( bool force = false )

virtual

save current data, force write

Saves the current data to storage.

When a file is closed, the document manager calls either Commit or Revert. If force is true, all data is written to storage. Commit checks any child documents and commits their changes to storage also. Before the current data is saved, all child documents must return true. If all child documents return true, Commit flushes the views for operations that occurred since the last time the view was checked. After all data for the document is updated and saved, Commit returns true.

Reimplemented in ocf::TOleDocument, ocf::TStorageDocument, and owl::TFileDocument.

Definition at line 584 of file document.cpp.

References _T, owl::TDocument::TList::Next(), NotifyViews(), owl::vnCommit, and WARNX.

◆ DestroyChildren()

void owl::TDocument::DestroyChildren ( )

protected

Destroy children first if we have any.

Then force close here as a last resort if derived classes have not done so. Since we have destructed down to a TDocument by now, derived closes will not be called.

Definition at line 309 of file document.cpp.

References Close(), and owl::TDocument::TList::Destroy().

◆ DestroyViews()

void owl::TDocument::DestroyViews ( )

protected

Destroys the views attached to this document.

Definition at line 318 of file document.cpp.

◆ DetachStream()

void owl::TDocument::DetachStream ( TStream & strm )

protectedvirtual

called from TStream destructor

Called from TStream's destructor, DetachStream detaches the stream from the current document.

Definition at line 452 of file document.cpp.

References owl::TStream::NextStream.

◆ DocWithFocus()

TDocument * owl::TDocument::DocWithFocus ( HWND hWnd )

virtual

Return pointer to this document or one of its child documents if the spcecified window parameter is a view associated with the document.

Note: Unlike 'HasFocus', this method allows you to distinguish whether the document with focus is a child document.

Definition at line 755 of file document.cpp.

Returns a pointer to the current document manager.

Definition at line 847 of file docview.h.

◆ GetDocPath()

LPCTSTR owl::TDocument::GetDocPath ( ) const

inline

Definition at line 984 of file docview.h.

◆ GetParentDoc()

TDocument * owl::TDocument::GetParentDoc ( )

inline

Definition at line 855 of file docview.h.

◆ GetProperty()

int owl::TDocument::GetProperty	(	int	index,
		void *	dest,
		int	textlen = 0 )

virtual

Retrieves the property identified by the given index.

If the requested property is text, then dest should point to a text buffer, and textlen should specify the maximum number of characters the buffer can hold, excluding the terminating null-character, i.e. the buffer must have room for (textlen + 1) characters.

If the requested property is numerical, then it may be requested either as text or in its binary form. To request the property as text, pass a text buffer as described above. To request the property in binary form, dest should point to storage of sufficent size, and textlen should be zero.

Non-text properties without textual representation, e.g. file handles, may only be requested in binary form, i.e. dest must point to sufficient storage, and textlen must be zero.

Returns: If the parameter textlen is non-zero, which means that the property is requested in string form, the function returns the length of the string, i.e. the character count excluding the terminating null-character. If the parameter textlen is zero, which means that property is requested in binary form, the return value is the size of the data in bytes.

If the property is text, and textlen is zero, the function fails and returns 0. The function also fails and returns 0 if textlen is non-zero and the property requested can not be expressed as text. It also returns 0 if the property is not defined.
