Re: [amibroker] Document-View architecture in A

[Tomasz Janeczko <groups@xxxxxxxxxxxxx>]

Hello,

Although architecture is called document-view, there are in fact THREE 
levels, not two.
Document->MDI Child Frame(s)->View(s)

Window in OLE interface context is not View. Window in OLE collection 
refers to so called MDI Child Frame
in which multiple views are hosted.
View is a chart *PANE*. And there can be multiple views (panes) of course.

In the past there was possibility to have more than one child frame per 
document as well
(via Window->New Linked),
but since new linking method is implemented (via buttons on the chart 
window) and floating windows
this possibility has been disabled because it interfered with floating 
windows.

Best regards,
Tomasz Janeczko
