So lets change the subject of the threads too, at every new question ;-)
Better for other to search later.

Right, one you managed to add text, using the text tool, you use the edittool
and
clcik on it to edit it again. Ctrl Mouse Left Down drags the text (while
editing).

void a2dStToolEvtHandler::OnDoEvent( a2dCommandProcessorEvent& event )
has the following part:
if ( event.GetCommand()->GetCommandId() == &a2dCommand_SetFont::Id )
{
a2dDrawTextTool* textTool = wxDynamicCast( tool, a2dDrawTextTool );
if ( textTool )
textTool->SetFont( a2dGetCmdh()->GetFont() );
}
So issueing a a2dCommand_SetFont command (search for it!!) will have the
a2dDrawTextTool react to that.
I think i should extend this to the edittool. Need to think about that.
In any case you can do it yourself, by deriving a thing or two, and handle the
same situation as above
but for the edittool.

Right.
Sometimes you might want to have SentPreAddDocumentEvent, or even
wxEVT_NEW_DOCUMENT,
study the next to know what happening:
bool a2dDocumentCommandProcessor::CreateDocuments(const wxString& path,
a2dDocumentFlagMask flags,
a2dDocumentTemplate* wantedDocTemplate, int dialogflags)
wxEVT_NEW_DOCUMENT
SentPreAddDocumentEvent
SentPostCreateDocumentEvent

Right, if part of the document, you would need something extra to not load/save
it.
a2dObject::Save()
checks IsTemporary_DontSave(), so setting the property like:
PROPID_TemporaryObject.SetPropertyToObject( lobj, false );
used here:
bool a2dCanvasObject::IsTemporary_DontSave() const
should not save it.
But using it as a background of a view is also an option.

Something like that, but after that you best convert it to a curve with bezier
parts in it.
