Persistent View State
The Explorer defines a set of standard view states:
- View mode, such as large/small icon view (or detail view)
- View attributes, such as snap to grid.
The Explorer provides a persistent medium to store these states and though
using them is not required, it is recommended. The setting is passed to the view
object by using IShellView::CreateViewWindow
and retrieved from it by using IShellView::GetCurrentInfo.
The Explorer also provides a persistent medium (a stream) to let the view
object store view-specific information (such as scroll positions or icon layout).
The view object can access this stream by calling IShellBrowser::GetViewStateStream
When the user is browsing from one folder to another, the Explorer passes the
pointer to the previously viewed IShellView
instance as a parameter to IShellView::CreateViewWindow
(before calling its DestroyViewWindow
). This allows the next view object to retrieve appropriate view state from
the previous view object (such as column widths of its details view), typically
by calling IUnknown::QueryInterface
on a private interface.
