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.

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.

Source PPT object from which the message originates.

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));

Add an error to the program.

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


Create the message and dispatch it. Then open the presentation.

msg = ErrorMessage('invalid slide',pre);


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