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.

See also:
  Application::GetEventInfos

Since:
  5.0

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

            using namespace XSI;

            // Function prototype for creating an event plug-in
            CString LoadEventPluginHelper();

            // Load the sample event plug-in
            CString strEventPlugin = LoadEventPluginHelper();

            // Iterate over the EventInfo Objects
            Application app;
            CRefArray eventInfoArray = app.GetEventInfos();

            for (LONG i=0; i<eventInfoArray.GetCount(); i++ )
            {
                EventInfo eventInfo = eventInfoArray[i];

                LONG lToken = eventInfo.GetToken();
                app.LogMessage( L"event token identifier: " + CString(lToken) );

                CString str = eventInfo.GetName();
                app.LogMessage( L"event name: " + str );

                str = eventInfo.GetType();
                app.LogMessage( L"event type: " + str );

                str = eventInfo.GetHandler();
                app.LogMessage( L"event handler: " + str );

                str = eventInfo.GetFileName();
                app.LogMessage( L"event handler file name: " + str );

                str = eventInfo.GetLanguage();
                app.LogMessage( L"event handler implementation language: " + str );

                bool bMute = eventInfo.GetMute();
                app.LogMessage( L"event is muted: " + CString(bMute) );
            }

            // Unload the plugin and deletes it
            app.UnloadPlugin( strEventPlugin, true );

            CString LoadEventPluginHelper()
            {
                // Loads the sample event plug-in if one is defined
                Application app;
                CString strEventPlugin = app.GetInstallationPath(siUserPath);
            #ifdef unix
                strEventPlugin += L"/Application/Plugins/SimpleEventPlugin.js";
            #else
                strEventPlugin += L"\\Application\\Plugins\\SimpleEventPlugin.js";
            #endif

                Plugin myEventPlugin = app.LoadPlugin( strEventPlugin );

                if (myEventPlugin.IsValid())
                {
                    return strEventPlugin;
                }

                // Gets the event wizard property
                CommandArray cmdArray = app.GetCommands();
                Command cmd = cmdArray.GetItem( L"CreateEventWizard" );

                CValue retVal;
                cmd.Execute(retVal);

                CustomProperty eventWizard(retVal);

                // Set the plug-in info
                eventWizard.PutParameterValue(L"PluginName", CString(L"MySimpleEventPlugin") );
                eventWizard.PutParameterValue(L"FileName", CString(L"SimpleEventPlugin") );
                eventWizard.PutParameterValue(L"ScriptLanguage", CString(L"JScript") );

                // Tell the wizard to register the following events
                eventWizard.PutParameterValue(L"siOnKeyUp", true );
                eventWizard.PutParameterValue(L"siOnKeyUpName", CString(L"MyOnKeyUpEvent") );
                eventWizard.PutParameterValue(L"siOnKeyDown", true );
                eventWizard.PutParameterValue(L"siOnKeyDownName", CString(L"MyOnKeyDownEvent") );

                // For the purpose of this example we use internal commands that are
                // part of the Event Wizard implementation to generate a plug-in
                // containing the new events

                cmd = cmdArray.GetItem( L"EventWizardGenerateCode" );

                cmd.Execute(retVal);

                // Load the plug-in
                app.LoadPlugin( strEventPlugin );

                return strEventPlugin;
            }

## Constructor & Destructor Documentation

EventInfo | ( |  | ) |

Default constructor.

~EventInfo | ( |  | ) |

Default destructor.

EventInfo | ( | const CRef & | in_ref | ) |

Constructor.

Parameters:

  in_ref | constant reference object.

EventInfo | ( | const EventInfo & | in_obj | ) |

Copy constructor.

Parameters:

  in_obj | constant class object.

## Member Function Documentation

bool IsA | ( | siClassID | in_ClassID | ) | const `[virtual]`

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

Parameters:

  in_ClassID | class type.

Returns:
  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.

Returns:
  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.

Parameters:

  in_obj | constant class object.

Returns:
  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.

Parameters:

  in_ref | constant class object.

Returns:
  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.

Returns:
  Token identifier (LONG).

CString GetHandler | ( |  | ) | const

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

Returns:
  Handler name as CString.

CString GetFileName | ( |  | ) | const

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

Returns:
  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.

Returns:
  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.

Parameters:

  in_bVal | True to disable the event, false to enables it

Returns:
  CStatus::OK Success.

bool GetMute | ( |  | ) | const

Returns whether this event is muted.

Returns:
  True for muted (disabled)
