ID for PPT API object, specified as a character vector. A session-unique ID is generated as part of object creation. You can specify an ID to replace the generated ID.

Source PPT object from which the message originates.

Tag for this PPT API object, specified as a character vector. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object.

An example of a reason for specifying your own tag value is to make it easier to identify where an issue occurred during presentation generation.

Message text, specified as a character vector.

Create the presentation.

import mlreportgen.ppt.*;
pre = Presentation('myPresentation.pptx');

Create the listener and add it to the message dispatcher.

dispatcher = MessageDispatcher.getTheDispatcher;

dispatcher.Filter.ErrorMessagesPass = true;
dispatcher.Filter.ProgressMessagesPass = false;

l = addlistener(dispatcher,'Message', ...
@(src,evtdata) disp(evtdata.Message.formatAsText));

Create the message and dispatch it before opening the presentation.

msg = ErrorMessage('Invalid slide',pre);
dispatch(dispatcher, msg);


Add content and close the presentation.

titleText = Text('This is a Title');
titleText.Style = {Bold};


Delete the listener to avoid duplicate reporting of message objects during a MATLAB® session.
