SCF_MENUACTION_EVENT Structure 

Occurs when the user selects an item on a menu page that causes a navigation to any page type other than a context menu.

The SCF_MENUACTION_EVENT Structure is identified by the enumeration value SCF_MENUACTION_EVENT Structure, which is passed as the value of the in_dwEventId parameter of the ISideShowEvents::ApplicationEvent Method.

The following table describes the parameters associated with the SCF_MENUACTION_EVENT Structure.

Parameter	Type	Description
PreviousPage	CONTENT_ID	The content identifier of the menu page on which the item was selected.

C++ Parameter Structure:

The following C++ structure is defined in the file WindowsSideShow.h and shows how the parameters of the SCF_MENUACTION_EVENT Structure are packaged to be passed to the ApplicationEvent method of the client-implemented ISideShowEvents interface. When this method is called, its in_pbEventData parameter points to a structure of the following form and its in_dwEventSize parameter is set to the size of this structure.

typedef struct tagSCF_MENUACTION_EVENT
{
    CONTENT_ID  PreviousPage;
    CONTENT_ID  TargetPage;
    UINT32      Button;
    UINT32      ItemId;
} SCF_MENUACTION_EVENT, *PSCF_MENUACTION_EVENT;
