Managing GUI Data with the Handles Structure
4-29
Application Data
Application data provides a way for applications to save and retrieve data
stored with the GUI. This technique enables you to create what is essentially
a user-defined property for an object. You can use this property to store data.
The GUI M-file uses application data to store the
handles structure.
When using the GUIDE-generated M-file, it is simpler to use
guidata than to
access application data directly.
