|
Class summary:
|
|
|
|
TFolder: This objects represents the print folder (local or
|
|
remote) that a user opens in the UI. It uses TConnectionNotify
|
|
to watch for new changes, and then creates TServers to hold
|
|
the server/printer data.
|
|
|
|
Destruction refcounted.
|
|
|
|
TConnectionNotify: if the Folder is local, then TFolder creates
|
|
and owns this. This object is responsible for telling
|
|
TFolder (via ConnectionNotifyClient) that the registry has
|
|
changed and TFolder should walk through its TServers, either
|
|
adding new ones or deleting old ones. (Compare EnumPrinters
|
|
with INFO_4 vs TFolder's linked list.)
|
|
|
|
Destruction sync'd with TFolder.
|
|
|
|
VDataSource: watch set of printers. This class is responsible for
|
|
keeping and updating data about a server/printer. It also
|
|
sends out notifications to the shell when something changes.
|
|
It uses TPrinter to get the data. TDSServer and VDSConnection
|
|
derive from this class.
|
|
|
|
Destruction refcounted.
|
|
|
|
TDSServer: watch a server with >=0 printers.
|
|
The single data source will return many printers. It
|
|
will internally enumerate masq printers, but it won't
|
|
return them via Get/EnumPrinters.
|
|
|
|
Inherits from VDataSource.
|
|
|
|
VDSConnection: watch a connection with 1 printer. This is
|
|
needed is true connects don't appear on the server, and
|
|
masq printers appear but are inaccurate.
|
|
|
|
Inherits from VDataSource.
|
|
|
|
TDSCTrue: watch a VDSConnection (true connect)
|
|
|
|
Inherits from VDSConnection since we gather information
|
|
from a separate handle.
|
|
|
|
TDSCMasq: watch a VDSConnection (masq connect).
|
|
|
|
Inherits from VDSConnection since we gather information
|
|
from a separate handle.
|
|
|
|
TNotifyHandler:
|
|
|
|
Utility class. Holder of IFolderNotify* handlers allowing to be
|
|
chained in a linked list.

Watch the registry looking for new printer addition. When

Client constructs with a registry path off of HKEY_CURRENT_USER

|
and passes in a callback. When the registry node changes, the

callback is triggered.
