EventInfo Class Reference

Detailed Description

The EventInfo class contains the information on a particular event such as its mute value, event handler, etc.

You access the name and the type of the event with SIObject::GetName and SIObject::GetType. Use EventInfo::PutMute to enable or disable events. EventInfo objects are created with Application::GetEventInfos.

Demonstrates how to create EventInfo objects and to access event information.

Member Function Documentation

bool IsA ( siClassID  in_ClassID ) const [virtual]

Returns true if a given class type is compatible with this API class.

in_ClassID class type.
true if the class is compatible, false otherwise.

Reimplemented from SIObject.

Reimplemented in TimerEvent.

siClassID GetClassID ( ) const [virtual]

Returns the type of the API class.

The class type.

Reimplemented from SIObject.

Reimplemented in TimerEvent.

EventInfo& operator= ( const EventInfo in_obj )

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

in_obj constant class object.
The new EventInfo object.
EventInfo& operator= ( const CRef in_ref )

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

in_ref constant class object.
The new EventInfo object.

Reimplemented from SIObject.

Reimplemented in TimerEvent.

LONG GetToken ( ) const

Returns the connection token for this event. Once an event is bound to an event handler function, XSI creates a connection token that uniquely identifies this connection.

Token identifier (LONG).
CString GetHandler ( ) const

Returns the name of the event handler function used for responding to the event.

Handler name as CString.
CString GetFileName ( ) const

Returns the name of the file implementing the event handler function.

Handler file name as a CString.
CString GetLanguage ( ) const

Returns the language name used to implementing the event handler function. VBScript, JScript, PerlScript, Python and C++ are all valid languages.

Language name as a CString.
CStatus PutMute ( bool  in_bVal )

Enables or disables the event. When set to true the event is muted (disabled). All handlers connected to a muted event are simply ignored by XSI when the event is fired.

in_bVal True to disable the event, false to enables it
CStatus::OK Success.
bool GetMute ( ) const

Returns whether this event is muted.

True for muted (disabled)
