Abstract:
|
||
|
|
|
||
|
|
The CComponent class implements several interfaces which MMC uses:
|
||
|
|
|
||
|
|
The IComponent interface is basically how MMC talks to the snap-in
|
||
|
|
to get it to implement a right-hand-side "scope" pane. There can be several
|
||
|
|
objects implementing this interface instantiated at once. These are best
|
||
|
|
thought of as "views" on the single object implementing the IComponentData
|
||
|
|
"document" (see ComponentData.cpp).
|
||
|
|
|
||
|
|
The IExtendPropertySheet interface is how the snap-in adds property sheets
|
||
|
|
for any of the items a user might click on.
|
||
|
|
|
||
|
|
The IExtendContextMenu interface what we do to add custom entries
|
||
|
|
to the menu which appears when a user right-clicks on a node.
|
||
|
|
|
||
|
|
The IExtendControlBar interface allows us to support a custom
|
||
|
|
iconic toolbar.
|
||
|
|
|
||
|
|
See Component.cpp for implementation details.
|
||
|
|
|
||
|
|
Note:
|
||
|
|
|
||
|
|
Much of the functionality of this class is implemented in atlsnap.h
|
||
|
|
by IComponentImpl. We are mostly overriding here.
