Trait SBApplicationDelegate 

pub unsafe trait SBApplicationDelegate {
    // Provided method
    unsafe fn eventDidFail_withError(
        &self,
        event: NonNull<AppleEvent>,
        error: &NSError,

}

Available on crate feature SBApplication only.

This informal protocol defines a delegation method for handling Apple event errors that are sent from a target application to an <doc ://com.apple.documentation/documentation/scriptingbridge/sbapplication> object.

You must set a delegate for the SBApplication object using the SBApplication/delegate method. If you do not set a delegate and have the delegate handle the error in some way, SBApplication raises an exception.

Provided Methods

unsafe fn eventDidFail_withError( &self, event: NonNull<AppleEvent>, error: &NSError, ) -> Option<Retained<AnyObject>>

where Self: Sized + Message,

Available on crate feature objc2-core-services only.

Sent by an SBApplication object when a target application returns an error Apple event.

• Parameters:

• event: A pointer to the Apple event sent to the target application causing the error.

• error: An object containing information about the error Apple event. Specific information may be included in the useInfo dictionary of the error object. The following table shows the possible keys for this dictionary.

Key	Description
ErrorBriefMessage	A short human-readable description of the error, as an
<doc
://com.apple.documentation/documentation/foundation/nsstring>
ErrorExpectedType	The type of data the target application expected, as an
<doc
://com.apple.documentation/documentation/foundation/nsappleeventdescriptor> object.
ErrorOffendingObject	The object that caused the error.
ErrorString	A full human-readable description of the error, as an
<doc
://com.apple.documentation/documentation/foundation/nsstring> object.
ErrorNumber	The Apple event error number, as an
<doc
://com.apple.documentation/documentation/foundation/nsnumber> object.

• Returns: If you return a result, it will become the result of the <doc ://com.apple.documentation/documentation/appkit/nsapplication/1428359-sendevent> that failed. Can be nil.

Safety

event must be a valid pointer.
