Examples

Create an Error Message

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};

replace(presentation,'Title',titleText);

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

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

open(pre);

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

delete(l);
