// This module contains the following classes:
|
|
//
|
|
// CCplUiElement
|
|
// CCplUiCommand
|
|
// CCplUiCommandOnPidl
|
|
//
|
|
// CCplUiElement is an implementation of IUIElement. This provides
|
|
// the necessary display information for use in the shell's webview
|
|
// implementation. The class also implements ICpUiElementInfo which
|
|
// is similar to IUIElement but provides the display information in
|
|
// a more 'final' form than a "<module>,<resource>" format.
|
|
// The ICpUiElementInfo interface is used internally by the Control Panel
|
|
// implementation.
|
|
//
|
|
// CCplUiCommand is an implementation of IUICommand. As with IUIElement,
|
|
// this provides the necessary functions for communicating with webview
|
|
// as a 'command' object (i.e. selectable 'link'). Also as with the
|
|
// previous class, CCplUiCommand implements an internal version of
|
|
// the public interface. ICplUiCommand provides two things:
|
|
// 1. A method to invoke a context menu.
|
|
// 2. An invocation method that accepts a site pointer. This site
|
|
// pointer is passed along to an 'action' object that may need
|
|
// access to the shell browser to perform it's function. It
|
|
// obtains access to the shell browser through this site ptr.
|
|
//
|
|
// CCplUiCommandOnPidl is another implementation of IUICommand that
|
|
// wraps a shell item ID list. It is used to represent the CPL
|
|
// applet items in a category view.
