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.
