* @doc TOM
|
|
*
|
|
* @module _tomdoc.H -- CTxtDoc Class |
|
|
*
|
|
* This class implements the TOM ITextDocument interface
|
|
*
|
|
* @devnote
|
|
* This class depends on the internal RichEdit CTxtStory class, but is
|
|
* separate, that is, a CTxtDoc has a ptr to the internal CTxtStory,
|
|
* rather than CTxtDoc deriving from ITextDocument. This choice
|
|
* was made so that edit control instances that don't use the
|
|
* ITextDocument interface don't have to have the extra vtable ptr.
|
|
*
|
|
* When this class is destroyed, it doesn't destroy the internal
|
|
* CTxtStory object (CTxtEdit::_pdoc). However the TOM client's
|
|
* perception is that the document is no longer in memory, so the internal
|
|
* document should be cleared. It's the client's responsibility to save
|
|
* the document, if desired, before releasing it.
|
|
*
|
|
* @future
|
|
* Generalize so that CTxtDoc can handle multiple CTxtStory's.
