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);
