Protecting and Positioning the Text Change Dialog

1 The user opens the Text Change dialog box by triggereing the main GUI’s

buttonChangeMe_Callback callback, which supplies the main G UI’s figure

handle as a property called

changeme_main.

2 The OpeningFcn for the dialog box validates the input by searching and

indexing into the

varagin cell array. If 'changeme_main' and a handle

are f ound as successive arguments, it calls

uiwait. This ensures that the

dialog GU I can exit w itho ut waiting for

OutputFcn to close the figure. If it

does not find the property or finds an invalid value, the modal dialog box

displays an error and exits.
