AttachEventHandler Method

The AttachEventHandler method attaches an event handler to an event. It uses the following values:

• consts.get( "SWE_EXTN_CANCEL_ORIG_OP" ). If SWE_EXTN_CANCEL_ORIG_OP returns a value of true, then Siebel Open UI cancels the operation for the predefined event handler. For an example that sets the value for SWE_EXTN_CANCEL_ORIG_OP, see Attaching and Validating Event Handlers in Any Sequence.

• consts.get( "SWE_EXTN_STOP_PROP_OP" ). If SWE_EXTN_STOP_PROP_OP returns a value of true, then Siebel Open UI stops the operation for the custom event handler from propagating the customization.

The AttachEventHandler method uses the following syntax:

AttachEventHandler(event_name, function_reference);

where:

• event_name identifies the name of an event.

• function_reference identifies the name of a method that the AddMethod method adds. For example, PHYEVENT_CONTROL_BLUR. Siebel Open UI calls OnControlEvent to trigger this event, and then calls the function reference in the scope of the corresponding presentation model.
